Red-Tailed Hawk

/

I had a busy June and July…just catching up with some of the things that happened. One was a flurry related to a red-railed hawk in State College, Pennsylvania. We were coming back from dinner the day before the finally packing up and cleaning out of my daughter’s apartment – heading off to Springfield, Missouri.

As we turned into the apartment parking lot a large bird flew low just over the car toward the base of a tree. There was a lot of noise in the underbrush….and the hawk came up empty. The squirrel escaped into a nearby tree and the hawk sat on the ground for almost a minute – seemingly befuddled.

The bird flew up to a light pole and sat long enough for me to get my camera out and take a picture. It still looks a little scruffy (and maybe frustrated) from the encounter!

My daughter had told me about the red-tails she had heard and observed frequently from her apartment window in State College…and I was thrilled to see one in action.

Summer Camp Volunteering – week 2

/

The theme for last week’s Howard Count Conservancy’s summer camps was ‘Fantastic Beasts.’ I spent a morning at Mt. Pleasant and the next morning at Belmont. At Mt. Pleasant there were three groups of campers….45 minutes for each. I used the dinosaur and mammal track rock found at NASA Goddard (saw it back when I was in the HOLLIE program) to initiate the conversation about extinct animals and fossils. There were some fossil shells from Calvert Cliffs and some of the campers had been there to explore themselves. I had on my ammonite shaped earrings too.

Then for some action: Two pans of water, a measuring tape and white board. A person put one foot into each pan (shoes on) and then stepped out and walked normally. The measurement team (usually two campers) measured heal print to heal print to determine the walking stride length. We measured the walking stride of the tallest and shortest in each group (and then everyone else because everyone wanted to know their stride length…or game it and take extra-long steps!). In the oldest group of campers, we measured the running stride (heel first and on toes). It was a great activity to further explore what information can be gleaned from tracks.

We transitioned into evidence of animals living today with some whelk shells and egg cases found on a beach. Some campers were surprised that the whelks were animals that still live in the ocean along the east coast of the US.

2019 07 IMG_5062.jpg

One of the junior counselors had participated in a dinosaur dig in Montana…and shared some pictures for her adventure with the campers.

It was a busy 45 minutes!

At Belmont, there were two groups of campers making Zentangle® tiles. I introduced the session using the NASA Goddard rock, the welk shells and my ammonite earrings….and then showed them patterns for beasts. The first group (younger) made octopus/jelly fish and tracks. The second group experimented with an ammonite type pattern, tracks and shells. The theropod tracks were the most popular. Many made some big therapod tracks and then some small ones (moms with babies). A variation from one camper: a therapod track….then a blank area where the therapod flew….then more tracks. One camper made mammal tracks. Both groups enjoyed adding colors after they made their patterns with the black Sharpie ultrafine pens.

The items below were ‘the cream’ of the articles and websites I found this past week. Click on the light green text to look at the article.

Dive beneath the pyramids of Egypt’s black pharaohs – The challenge of excavating a 2,300-year-old tomb that is submerged in rising groundwater.

Another Fire in Greenland – There have been more reports of fires in the far north this year. Evidently warm dry air causes Arctic circle landscapes (that are not ice and snow) to be very flammable…fires start and burn quite easily.

Top 25 Wild Bird Photographs of the Week: Pigeons and Doves – National Geographic – I was surprised at the diversity of these birds.

Call for green burial corridors alongside roads, railways and country footpaths -- ScienceDaily – I wonder how many other countries have a similar problem. Space for burials is probably already a challenge for almost all large cities.

How the sound in your office effects your mood – Aural architecture….how we listen to buildings, the sound within buildings, and how we react. It isn’t considered very often in the current built environment except for things like concert halls and sound proofing. Maybe in the future it will be. One segment of the article talked about the need for quite and nature sounds in city soundscapes…much better than sirens and traffic noise.

Air pollution speeds up aging of the lungs and increases chronic lung disease risk -- ScienceDaily – A large study…another reason to do everything we can to improve air quality.

Banding Hummingbirds – Banding larger birds has it’s challenges but a hummingbird….I’d never heard someone describe it. Kudos for the people that have the touch to do it well.

Engineers develop chip that converts wasted heat to usable energy -- ScienceDaily – Interesting idea…I wonder how long it will take to get this type of technology into laptops and solar panels?

How a Pokémon-like Card Game Is Changing the Way People Learn About the Environment – What a good idea. I hope more teachers start introducing their students to the Phylo game!

Solar panels cast shade on agriculture in a good way – Research from the University of Arizona…how solar panels could shade plants to help them survive in a hotter environment…and the plants help cool the air under the solar panels as they produce electricity! The plants that might do best are the leafy greens that tend to wilt in the mid-day heat. The leaves grow bigger in the shade too! Production of nutritious food and renewable energy in the same system.

Zentangle® - July 2019

/

There was quite a lot of variation on the Zentangle front in July. There was a challenge on the long road trip days and then being very busy the rest of the time. Some days there was plenty of time to make several tiles…other days were too short to do anything other than on the critical path to get my daughter moved to Missouri! In the end – I still had a lot of tiles to choose from to come up with 31 tiles for July. The normal variation is seen in this first group made on the iPad with the Apple Pencil using the Procreate App. I found the iPad the easiest to work with at the end of a long day of driving.

I started experimenting with some square paper coasters for tiles early in the month.

There was also a series that were created with a spiral string then a single pattern….all on the iPad.

The most different tiles the samples I made using the butterfly tiles I used with the summer campers last week. It was fun experimenting with the shape and working with symmetry.

Brookside Gardens – July 2019

/
2019 07 IMG_4948.jpg

Even though the weather has been very hot this month, there are still plenty of flowers at Brookside Gardens that are weathering the heat.

The buttonbushes have all stages of flowers and seed formation now.

The green cones are forming on the bald cypress.

c 2019 07 IMG_5018.jpg

The butterfly weed seed pods are bursting open even as the Monarch caterpillars are munching on their leaves. The common milkweed pods are still green.

m 2019 07 IMG_5045.jpg

There are quite a few butterflies out in the gardens enjoying the flowers. The tiger swallowtails particularly enjoy the Joe Pye Weed. Last weekend I noticed more Monarch butterflies in the gardens. Maybe these are arriving from Mexico although it certainly is later than usual.

2019 07 IMG_4925.jpg

I walk around the gardens before my shifts at the Wings of Fancy exhibit. There were only two this month because of the travel I did during the first half of the month. There are plenty of things to see like chipmunks and milkweed bugs.

I even found a feather on a leaf that I could get close enough for a macro shot.

2019 07 IMG_4970.jpg

In the exhibit, the caterpillars are eating and growing. There was a Palamedes swallowtail caterpillar that had a ‘sun worshipper’ pose on a ‘excessive heat’ day.

2019 07 IMG_5001.jpg

There are plenty of Monarch caterpillars of all sizes on butterfly weed in the caterpillar house as well.

2019 07 IMG_5003.jpg

Inside the conservatory, I don’t have much time to take pictures of butterflies (lots of visitors) but I did manage a few. One day it was so hot that even the butterflies were desperate for water (on the floor) and not flying as much.

Ten Little Celebrations – July 2019

/

July 2019 was a busy month with two weeks of the months a way from home and volunteering. We’re in the thick of summer!

2019 07 a IMG_9498.jpg

4th of July. There is the holiday celebrated with fireworks and food and family early in the month. I was in Texas rather than at home.

2019 07 y IMG_9565.jpg

Yellow-Crowned Night Heron. It’s thrilling to see a heron that I don’t see all that often…a serendipity sighting during a hike to celebrate.

Easy drive through Arkansas. I celebrated that the road through Arkansas on my way back to Maryland from Texas was a lot better than I expected – good road, no construction, no accidents.

Marigolds. I savored the flowers available for cutting when I go to pick up my CSA share every week. Marigolds are among my favorites….but the sunflowers and amaranth and zinnas are good too.

Pittsburgh to Springfield MO in a day. It was a long drive with my husband and I caravanning. We both celebrated when we arrived – tired but otherwise unscathed.

At home again. After being away for 2 weeks (not concurrently) I had several days celebrating just being at home again.

20190706_100200.jpg

Prius Prime. I celebrated my car that has excellent range and is easy to drive. It still feels a little new and it’s 2.5 years old! These recent road trips have added quite a few miles.

Surviving a very hot Wings of Fancy shift. I celebrated that having something cold at each break (grapes, popsicle, Gatorade) and drinking lots of water enabled me to be fine at the end of the shift….and even relaxed in my air conditioned car on the way home.

Summer campers making butterfly Zentangles. Celebrating sharing an activity with campers….enjoying their creations as much as they did.

Toad under the oak tree. There is a toad that is making its home in the day lily forest under the oak tree. I celebrated that our yard is providing suitable habitat (there was a very small black rat snake there too…which I am choosing to celebrate too…but I didn’t take time to get a picture).

20190727_081335.jpg

3 Free eBooks – July 2019

/

So many good books…so little time.

04g 19 07.jpg

International Museum of the Horse. A Gift from the Desert: The Art, History and Culture of the Arabian Horse. Lexington, Kentucky: International Museum of the Horse. 2010. Available from Internet Archive here. This is the illustrated catalog from an exhibition held in 2010; the presenting sponsor was the Saudi Arabian Equestrian Federation. The photographs of objects and locations included in the digital book tell the story more than the words.

Bing, Siegfried (editor). Le Japon artistique : documents d'art et d'industrie. Paris: Librairie Centrale des Beaux-arts. 1888. Available from Internet Archive here. The French version of a magazine that appeared simultaneously in English, French, and German. It helped introduce Japanese art and artworks to the West. I had previously looked at the English version but didn’t realize they were the same thing until I looked back at my master booklist. I still enjoyed the illustrations…again.

44c 19 07.jpg

Gould, John. The Birds of Australia. London: R and JE Taylor. Seven volumes originally published in the mid-1800s and available from Internet Archive here . The illustrations are probably the work of his wife – Elizabeth Gould. She died in 1841 shortly after giving birth to her 8th child. It wasn’t until 1938 that a collection of her letters from Australia were discovered and became the basis for a biography.

The items below were ‘the cream’ of the articles and websites I found this past week. Click on the light green text to look at the article.

Narwhals and belugas can interbreed -- ScienceDaily – It is a unique case….apparently not something that is common at all. It also utilized some relatively recent analytic tools to determine that the hybrid was a first-generation hybrid between a female narwhal and male beluga…and it was a bottom feeder rather than feeding like either of the parents.

Photography in The National Parks: Where Will That Trail Take You? Creating A Theme – For me - themes most often emerge from the experience rather than something I think about specifically in advance.

'Anthropocene Project' Artfully Captures How Humans Change Earth's Landscape: Goats and Soda: NPR – Some photographs from an exhibit currently in Bologna, Italy…depicting obvious, physical incursion on the Earth’s landscape created by humans.

Photographer Explores the Quiet Beauty of Venice at Night – A very different perspective on the city…sinking in its lagoon.

'Bathtub rings' around Titan's lakes might be made of alien crystals -- ScienceDaily – Rings made of solid acetylene and butane – maybe. It’s what happened in the lab. A spacecraft will need to visit Titan to know for sure.

Top 25 Wild Bird Photographs of the Week: July – National Geographic Society Newsroom – Birds!  There are so many different kinds out there.

Cholesterol medication could invite diabetes, study suggests: Patient data shows association between statins and type 2 diabetes -- ScienceDaily – A drug prescribed to reduce risk of heart attack and stroke…doubles the risk of diabetes diagnosis which would require other drugs to treat…for the rest of the person’s life. Not a good prospect.  

The Pomological Watercolors: A Collection of Watercolor Fruit Paintings – Watercolors of fruits and nuts created over 56 years beginning in 1886 by the US Department of Agriculture. They have recently been digitized and are available via the Pomological Watercolor Database. It’s not as easy to browse as a book in Internet Archive, unfortunately.

Ice Cores Preserved 1,500 Years of Industrial Lead Levels - Archaeology Magazine – I was surprised that lead levels in the atmosphere now are 60x higher than in the medieval period and that is an 80% decline since the enactment of the 1970 Clean Air act in the US. How is the lead in the air we breathe impacting our cognition – particularly for children?

Found: An ‘Undisturbed’ Roman Ship Near Cyprus | Smart News | Smithsonian – Lots of amphorae. Cyprus’ location would have made it a link on the trade route that spanned the Mediterranean but studying a wreck like this one could fill in more of the details.

Zooming – July 2019

/

I probably use the zoom on my camera for most of my pictures. It allows me to frame the picture the way I want and to ‘see’ the environment better than I can with just my eyes. Sometimes I am at the limit of what my camera can do. For example – the tiger swallowtails are particularly numerous in my back yard this summer and I kept seeing then flying under the maple tree where my compost pile is located. I used my camera like binoculars to see that the swallowtails were ‘puddling’ in the compost pile after a rain. They must have been enjoying the nutrient rich water!

a 2019 07 IMG_9670.jpg

There was a smallish robin that fluttered down from the maple and sat in the grass – just looking around for a few minutes before returned to the tree. It didn’t look or find a worm! Probably a fledging.

a 2019 07 IMG_9658.jpg

On the hottest day of the summer (so far), a wasp got a drink from our bird bath. Sometimes I find wasps that have drowned in the bird bath but so far it hasn’t happened this year. Maybe they are getting better as just getting the drink that they need.

a 2019 07 IMG_9719.jpg

Now enjoy the slide show of other zoomed pictures from this month:

  • Plane tree

  • Fireworks

  • Pocket prairie plants

  • Yellow crowned night heron

  • Female cardinal

  • Fawn

  • Goldfinch

Red-Bellied and Downy Woodpecker Juveniles

/

A week ago, I saw two juvenile woodpeckers come to the bird feeder handing on my deck.

At first, I saw an adult Red-bellied Woodpecker coming to the feeder, get seeds then fly back to the maple tree.

Soon it became obvious that there was a fledgling because it followed the adult bird to the deck. The fledgling got as far as the railing and then flew back to the maple without attempting to get seed from the feeder. A few days later, I heard the fledging again and it seemed to still be following the parent…with a little more skill.

2019 07 rb IMG_9690.jpg

There was a juvenile Downy Woodpecker at the feeder on the same day as I saw the fledgling red-bellied woodpecker. It is a Downy rather than Hairy Woodpecker because it has black spots on the white outer tail feathers.

I had seen a juvenile downy woodpecker back on June 9th which must have been from an earlier brood. It had the same clumsy flight pattern as the one I saw on July 19th.

The woods behind our have been good places for the woodpeckers this summer!

Butterflies in the Garden

/

Last weekend at Brookside Gardens there were a lot of flowers blooming (Joe Pye Weed and Coneflowers) in the high heat and attracting butterflies. Most of the butterflies were Tiger Swallowtails. I took pictures and then categorized them when I got home. The males are slightly smaller and less colorful.

The females are larger and have more blue scales.

And then there are the dark morphs of the tiger swallowtail that are all female.

While I was doing the categorization, I found one that was not a tiger swallowtail. It was a Spicebush Swallowtail! It looks very similar and I never try to distinguish these dark swallowtails in the field. I just take pictures and make the identification when I get home.

There was some butterfly drama just before I went into my Wings of Fancy shift. In the garden near the conservatory give shop – there was a butterfly moving oddly. I quickly determined that it wasn’t the butterfly moving itself; it was a praying mantis eating the butterfly under a flower! One less dark morph of the tiger swallowtail in the garden….

Road Trips to Springfield, Missouri

/

I’ve now made 3 road trips from Maryland to Springfield, Missouri  (one in June and 2 in July) so I am getting familiar with the route. It’s a two-day trip which I prefer to do with one slightly longer day. On one of the trips to Springfield we drove from near Pittsburgh to Springfield in one day….and I won’t do that again. Springfield, Ohio is a good midway point that my daughter picked (she liked the idea of going from Springfield MO to Springfield OH); it is my preference too.

I’ve learned where there is hard driving (lots of curves and trucks going at high speed) and where the current construction is. Hopefully the construction will be mostly done by the next time I go and there might be a better route through the Alleghenies that we’ll try.

20190716_064523.jpg

There are two favorite rest stops along the way. One is close to Springfield and focused on Route 66 which makes a diagonal path through Missouri from St. Louis angled toward Tulsa, Oklahoma. They have a map on the floor of the rest top.

20190716_152810.jpg

2)The other rest stop was in Indiana and I like it for two reasons: 1) It has plants that remind me of my grandparents in Oklahoma back in the 60s. They grew ‘rubber trees’ indoors in the winter then put them out in the flower beds near the house in the summer…almost burying the pots…then trimmed them back and brought them indoors for the next winter. This rest stop has the plants in the center planter inside the rest stop!

The rest stop also had ‘pocket wetlands’ on two sides. The red-winged blackbirds were numerous, and I heard frogs as well. The sky was threatening (thunderstorm imminent) and we were pushing to get to the hotel before the storm, so I didn’t have time to investigate more. Maybe next time. ..

Josey Ranch Lake – July 2019

/

Last April when I walked around Josey Ranch Lake, there were grackles, coots and cedar waxwings.

The coots and cedar waxwings were gone, but the grackles were around – and noisy. The Great-tailed Grackles are probably the most noticeable bird at Josey Ranch Lake (along with pigeons) but what made them more interesting this time were fledglings – new enough that their parents were still feeding them occasionally. Note that the adults have yellow eyes that is indicative of Great-tailed Grackles rather than Boat-tailed Grackles (dark eyes). The juvenile grackle has dark eyes…but since a yellow eyed adult was feeding it, I expect it is a Great-tailed juvenile.

There were white feathers on the grass.

2019 07 e IMG_9575.jpg

And three kinds of white birds that I saw in the short time I was there: 1) a Great Egret. At first it was fishing in the water then strutted out onto the concrete walk. Those toes are long…and the feathers were ruffling in the breeze!

A resident 2) Mute Swan was on the lake. I didn’t see one in April, but they were probably there. I’ve seen one juvenile years ago, but I don’t think there have been any cygnets in the past few years.

2019 07 s IMG_9585.jpg

A 3) Snowy Egret preened and hunted in the shallows. The wind ruffled its feathers. It stayed in the water, so I didn’t see its yellow socks, but the beak and size are distinctive enough for the identification.

As I walked around the lake, I noted spider webs and shelf fungus. The cloudy day was not the best for photography, but the morning was my only chance to be there.

The high point of the morning was an accidently sighting of a Yellow-Crowned Night-Heron. I wondered if it was the same one I had seen there in June of 2018. This one was in one of the smaller ponds near the lake. I was looking through the vegetation to see if there were any ducks on the pond when I saw it…the only bird in the pond. It didn’t seem to notice me. It was casually hunting the area; I didn’t see it catch anything.

Josey Ranch Pocket Prairie – July 2019

/
2019 07 a IMG_9522.jpg

The Josey Ranch Pocket Prairie has gotten taller since I visited back in April. At first glance the dominant colors are greens and browns. It takes a closer look to notice the wild flowers that are still in bloom and the seed pods that many are already beginning to form. I thought about what it would be like to walk through a larger prairie – that continued for as far as the eye could see – it would not be an easy stroll. The plants are intertwined and densely packed. They are at least waist high. And there would be no shade from the heat. Streams large enough to support trees would be precious.

2019 07 a IMG_9523.jpg

The flowers are like jewels in the greens and browns. I used the zoom to get flower pictures and stayed on the path. It was still early enough in the day that the temperature was cool, and I was the only one in the pocket prairie even though the morning commuter traffic was just yards away. I was alone but not too alone.

Kudos to the crew that established and maintain the Josey Ranch Pocket Prairie!

Springfield Botanical Garden

/

My daughter and I took a break from unpacking into her new home for  a short walk around the Springfield (Missouri) Botanical Gardens. We parked near the area that the Master Gardeners created and maintain. There were a lot of things in bloom…and veggies growing too.

2019 06 IMG_9424.jpg

The morning was heating up and we realized we should have come earlier in the morning for our walk. We made our way through several other garden areas. The Hosta area looked inviting (very shady and probably cooler that much of the garden) but we decided to make a loop and come back sometime when it was cooler.

I knew they had a native butterfly exhibit that I wanted to see. It is in a mesh tent. The butterfly that was new to me was the zebra swallowtail – evidently more common in Missouri than it is in Maryland. Maybe they have more paw paw trees (the host plant for the caterpillar) than we do.

As we walked back to the parking lot (the Botanical Center building was not open during the time we were there), we saw the Monarch Butterfly life cycle sculpture/play area. Very clever. Next time I am in the garden maybe there will be children playing on it.

2019 06 IMG_9440.jpg

July 4th Fireworks

/
2019 07 a IMG_9498.jpg

I was in Carrollton TX on the 4th of July. It was short walk from my parents’ house to a good viewing area for the city’s fireworks. Other people had the same idea so there was a community block party-like atmosphere. Somebody brought a boom box to provide music. My sister had popsicles to keep us hydrated and cool. Everyone was ready by 9:30 PM when the fireworks started. We had carried folding chairs with us…but I ended up not using mine because I was taking pictures. My camera was on a monopod and I used the ‘fireworks’ setting. It’s not a setting that can shoot in quick succession because it knits together several images in the camera. The result is pictures that show a lot of color. I also liked some of the pictures where I managed to ‘move’ during the time it was capturing the multiple images…the streaks and squiggles look like abstract art. The best pictures are included in this post.

The electrical wires are sometimes visible in the pictures – sometimes not. They were always there.

After the fireworks show was over…we walked back to the house….then heard fireworks again. Somehow the finale had been delayed. Aargh! No pictures.

Brookside Gardens – June 2019

/

The plants at Brookside Gardens are lush this time of year. I took pictures before every shift with the butterflies…and sometimes afterward as well.

The gardeners that maintain the north conservatory succeeded in getting a lotus to bloom in the pool there. When I photographed it, there was a tiny insect on the flower….a little pollinator?

Now for the outdoors - Some days it was raining and I focused on water on the plants; some days I worked with lighting to get the background dark; other days I was intent on filling the frame with a single flower or the unfurling of a single frond. Some plants are still in bud and others are already making seeds. I find myself being pleased with how many I can easily identify but even happier to just savor the shapes and colors…remember the smells. June is a great month for gardens here in Maryland.

Brookside Gardens – Butterflies and more

/
a 2019 06 IMG_4680.jpg

Brookside Gardens’ Wings of Fancy exhibit was one of the places I volunteered in June – one of my happy places. One of my shifts was so cloud-covered and rainy that butterflies were still roosting in the fiscus at mid-morning.

a 20190610_102103.jpg

There were more clearwing butterflies in the conservatory that earlier in the season – enough that I saw one or two during most of my shifts.

a 20190617_101148.jpg

There aren’t as many paper kite butterflies this year…but they are still one of my favorites.

b 20190610_101317.jpg

The overall favorite for most people is the blue morpho; it’s one of mine too although for more than the blue color…I like the orange markings on the underside and body too. I manage to get some quick pictures during times when there are very few or no visitors in the exhibit.

And there were many other kinds of butterflies that posed for a picture at handy times.

And then there is the caterpillar house. Most of the caterpillars that were in the house during June were Julia Longwing or Zebra Longwing; both use passion flower as the host plant for their caterpillars.

p 20190624_120917.jpg

Toward the end of the month the eggs of the Palamedes swallowtail hatched….and the very small caterpillars begin to make their visible mark on the leaves. When they get bigger, they’ll have ‘eye spots’ to keep the predators away.

There were butterflies outside in the gardens too – mostly tiger swallowtails and skippers.

The bees enjoy the flowers too.

Sometimes a dragonfly would sit for long enough to be photographed.

d 2019 06 IMG_4747.jpg

Birds like the gardens. A goldfinch and cardinal were near the conservatory one morning before my shift. I also saw a catbird that same morning but it flew away before I could get a photograph.

But the high point of the animals at Brookside was a box turtle! I had just exited my car and saw it emerge from a bed at the side of the conservatory and walk across the concrete in front of the service door to the north conservatory.

h 2019 06 IMG_4791.jpg

It continued until it was close to the seal between the two doors then looked up like it expected the door to open. I wondered if it had – sometime in its life – spent some time inside the conservatory.

Older forests resist change, climate change, that is -- ScienceDaily  - A study from the University of Vermont. But there are a lot of other changes in the forest too – the advent of non-native diseases like emerald ash borer and the explosion of deer populations so that there is a lot less understory in the forest (and few young trees). Is the net still that old forests resist change more effectively than younger ones?

Top 25 Wild Bird Photographs of the Week: June – National Geographic Society Newsroom – The always beautiful series of bird pictures.

Expanding the temperature range of lithium-ion batteries ScienceDaily – I’ve noticed the battery in my Prius Prime does not last for as many miles in the winter as it does in the summer. It’s one of the issues I want improved before I buy my next EV.

Chattanooga Becomes First U.S. Airport to Run Entirely on Solar – YaleEnvironment360 – Congrats to Chattanooga on this milestone. Evidently the first airport to do it was Cochin International in Kerala, India which went 100% solar powered in 2015.
