Florida Scrub Jays at Cruickshank Sanctuary

/

The second morning of the Space Coast Birding and Wildlife Festival, it was raining when we got up. When we headed out at about 8 AM, it was thunderstorming …complete with nearby lightning. By the time we arrived at the Helen and Allan Cruikshank Sanctuary, there were puddles everywhere but was the lightning was gone and the rain was slowing. We headed out walking around the larger mud puddles.

The sanctuary is managed to stay scrub – which requires periodic burning. There are occasional live oaks, but most vegetation is low…and the Florida scrub jays love it.

They were everywhere and acclimated to people being around. Even with the light rain and thick clouds, I managed to take some pictures. The blue color changes in different light but I discovered that once I zoomed in enough, the birds were colorful even in the low light (from afar they looked like dark gray birds!). The birds bury acorns in sand and remember where buried food is better than squirrels. It was obvious that people had left peanuts for the jays because we saw a bird dig up a peanut still in its shell!

The sanctuary is an island surrounded by housing development…and the invasive Brazilian pepper is growing among the native vegetation. I learned that some people have skin sensitivity to the plant – like poison ivy.

There were mounds of lichen on the ground. It looked like reindeer moss (maybe the same genus: Cladonia). I went back to take a close up picture with my smart phone and macro lens….even though the next line of rain was coming through and the hiking group was dispersing a bit early.

Port Canaveral Boat Tour

/

After we picked up our registration material for the Space Coast Birding Festival, we went out for lunch then headed to the Kelly Park dock for a boat tour of Port Canaveral. It was a pontoon boat with bench seats. Shortly after we sat down – it started sprinkling then raining harder. We got off the boat to stand in the drier picnic pavilion in the park. The wind was blowing enough that we had to stand well under the pavilion roof.

2019 01 IMG_1434.jpg

I took a picture of a little blue heron that did not seem bothered by the rain and wind at all.

Then the rain stopped, the seats were dried off and we headed out only about 15 minutes late. I took some pictures of barnacles around the dock area.

We saw evidence of manatee in the water….the flat circles of water as they swim along…and then the tips of their noses when they come up for air. The ‘slow speed’ signs did indeed mark areas where there were manatee in the water.

2019 01 IMG_1464.jpg

We saw birds along the canal before we got to the locks: anhinga,

2019 01 IMG_1473.jpg

Great blue heron (looking scruffy from the recent rain),

2019 01 IMG_1477.jpg

Osprey,

2019 01 IMG_1479.jpg

And double crested cormorants.

We entered the lock and tied up.  I took some brown pelican portraits while we waited.

Then the gates started to open.

2019 01 IMG_1538.jpg

The pelicans road the little water wave as the water leveled…and one took flight.

There was an immature brown pelican outside the lock area. The light on the water was perfect.

2019 01 IMG_1714.jpg

The high point of the trip was a frigate bird soaring overhead. I just watched it. My husband got the picture.

2019-01-23-SCWBF Day 1 6D-130.jpg

There was a cruise ship and the SpaceX barge (used for rocket recovery) in Port Canaveral itself. I was more interested in bird pictures…so didn’t document those sights.

We headed back through the lock. I turned back to take a picture of the white pelicans grouped on the bank and

The horseshoe crab shells that accumulated to the side of the lock.

2019 01 IMG_1747.jpg

I managed to take a picture of a bald eagle just before it flew way…a good ‘last picture’ before we docked back at Kelly Park.

Road Trip to Florida

/

Last week we drove down to Florida for the annual Space Coast Birding and Wildlife Festival in Titusville. I’ll be posting about the trip for the next week or so…but today the post is focused on the drive itself. We left the house at 5:30 AM to beat the worst of the commuter traffic around Washington DC. Venus and Jupiter were visible in the darkness to the east. We made a very cold rest stop at 6:30 AM south of DC and on I95…the interstate we would take all the way to Florida. The temperature was in the low teens. Leaving early had achieved its purpose; no stop and go or slow traffic! We listened to Planetary Society podcasts that my husband had on his phone.

20190122_072031.jpg

It was getting light by our next rest stop at about 7:30 still in Virginia. It was a newer rest stop with a compass in the entry floor, an area to charge/use laptops (we never spend that much time at a rest stop), and a toddler toilet (I’ve only seen these in the newer Virginia rest stops….what a wonderful feature for young families).

We took I295 around Richmond and stopped at a McDonalds for a second breakfast. The sun was shining in our eyes. Turkey vultures were soaring. By 9:40 AM we were in North Carolina. I remembered the rest stop from a previous trip: red tile strips and glass brick.

20190122_094044.jpg

There was a bird’s nest in the tree just outside the building – easy to see in the winter.

20190122_101759.jpg

The next stop was a large truck stop in Kenly, North Carolina- with a large tile mosaic in the entry.

We stopped for lunch at Arby’s in Lumberton, North Carolina that did not take long and then were back on the road – crossing into South Carolina and seeing a Honda plant with its own exit from the highway and water tower.

20190122_131656.jpg

The next rest stop did not have any structural distinction, but I did notice a large river birch in the picnic area.

I saw a hawk fly low across the road in front of us and began to see black vultures along with turkey vultures. Our last rest stop for the day had green tile and a skylight in the facilities. The picnic area had sabal palmettos – matching the South Carolina license plates.

We stopped for the night in Savannah – just off I95.

20190123_074843.jpg

We didn’t start out as early the next morning. It was already beginning to get light. We made a stop, still in Georgia, where the roses were blooming.

As we drove into Florida a line of clouds moved in.

2019 01 r IMG_3447.jpg

I took pictures of the Dames Point Bridge going around Jacksonville (some morning commuter traffic).

At the next rest stop there was a pond with a fence around it (with signs warning of snakes)…but I braved the short walk up to the fence (didn’t see any snakes). I took pictures of the birds around the pond…the first for the trip: hooded mergansers,

White Ibis (mature and juvenile), and

2019 01 rIMG_3484.jpg

Not bad birding at a rest stop along I95.

We arrived at the registration desk for the festival a little after 11.

Smartphone Nature Photography – part 2

/

Continuing from yesterday’s post….

Identification. Sometimes I take a lot of photos so I can identify something later. This was the case with these caterpillars. They were devouring dogwood plants at Brookside Gardens last summer. They remind me of lemon bars (yellow custard underneath powdered sugar). I defaulted to thinking they were a moth or butterfly larvae…but they turned out to be a dogwood sawfly larvae!

Stories. Some pictures tell a story. If you are aware at the time…make sure you take the pictures of the whole story. This Achemon Sphinx Moth was discovered by summer campers going out between rain showers during a nature photography activity. Moths are more active at night and usually are hiding in foliage during the day. This one was on the ground and twitching. I knew from experience in the Brookside Gardens Wings of Fancy exhibit that it had probably been bitten by a spider. We took our pictures and left it where it was. I regret that I was too busy helping campers to keep my camera at the ready to shoot the moth being pulled between two rocks – presumably by the spider that never did make itself visible.

20180724_112642.jpg

Insects. Insects can be very fast moving and difficult to photograph no matter what camera you have. They often are slow or immobile when it is cooler. Cool mornings are good to find cicadas – silent and still…but maybe not dead. Butterflies can be under leaves roosting if it’s cool…or it is dusk and they are seeking a place to spend the night. Then there are masses of milkweed bugs that are prevalent in the fall. They are moving but there are so many that it’s easy enough to get a good number; I always try to figure out how many instars are shown in the same picture.

And sometimes it is just luck. This blue morpho sat on my wrist while I was at the exit of last summer’s butterfly exhibit at Brookside Gardens. I had my phone on the lanyard so was able to pull it out and one-hand the phone to take the picture.

20180813_093825.jpg

Specimens. There are nature photography shots that might be of specimens rather than out in the field. The shot of the blue morpho wing was from a specimen that had died using the 15x macro lens. I’ll try the 60x next summer. I included the label in the picture of the dogwood tree cookie…for documentation; I liked the irregularity of the rings.

Wet day color. Sometimes a rainy-day hike is a good thing. The color of fungus is often more intense on these days – and the phone handles the raindrops better than more traditional cameras.

Light. Sometimes an image is made by something special about the light – spotlighted ferns, the shadowing of a sectioned Nautilus shell, a sunrise.

Clipping. Because the camera only has a digital zoom, I often take the picture without zooming then make a clip after I get home. In the example below – the two butterflies (tiger swallowtail and male monarch) are clearly identifiable even though the clip has a painterly look.

So – go out and take some pictures! The only blooms we have outdoors right now are the witch hazels. There are other winter opportunities too: tracks in the snow (or mud), seed pods, snow landscapes, and ice crystals. And maybe a squirrel will be close enough and still enough….

Smartphone Nature Photography – part 1

/
20180721_083226.jpg

We almost always have our smartphones with us….ready for those natural events that just happen and for planned photoshoots. I pulled together a presentation of a Maryland Master Naturalist retreat on the topic and am using it as a basis for the blog posts for today and tomorrow.

Gear

Learn about the camera in your phone. Two critical aspects: 1) Usually the autofocus is reasonably good but tapping on the screen where you want the focus to be can sometimes improve results. Do some experiments to see how close you can be and maintain the focus on your subject. 2) Realize that the zoom is digital – not optical. You are better off getting close to your subject rather than zooming. This is difficult if your subject is an animal that will move if you get close. Birds are notoriously difficult to photograph with a phone.

Consider a lanyard. I like to carry my phone on a lanyard (one that is structured to not obstruct the camera) so that I can be ‘hands free’ while I am hiking or rolling over logs…just doing regular naturalist things.  I want my phone to be easy to access – easier than getting it out of a pocket or pack.

20190115_084222.jpg

I enjoy using macro lenses. I have 3 different kinds (8x, 15x, and 60x) and tend to use the 15x clip the most. Sometimes I just have it on my phone so that I can move it over the camera as needed. The depth of field is very shallow with the magnification and the phone must be close to the subject. Practice the best stance to steady your hands. I find that tucking my elbows into my body helps….and using one had to hold the phone and the other to take the picture.

Examples of Smartphone nature photography

BioBlitz. Almost all the BioBlitz pictures are taken with smartphones or tablets. Sometimes we use hands for scale – and sometimes the macro lens gives a new perspective! These are pictures taken during BiobBlitz: spotted salamander, wooly bear caterpillar, milkweed.

Landscapes.  The joy of being outdoors! Try to get something of high interest in the landscape: the trail as a leading line, clouds over the trees, an early winter scene with bare trees/large rock/pines.

20171201_095022.jpg

Macro. The macro lens offers to many opportunities to observe more closely than you can observe with just your eye: clams filter feeding, the center of sunflower.

A chicory flower, a newly hatched Monarch butterfly caterpillar turning to eat its egg covering, and damselfly larvae.

A few minutes observing. I play a game with myself looking closely at one thing and taking photos as fast as I can over a short period of time. In this case it was a sweet bay magnolia. There were seed pods at several stages of development and some eggs under a leaf (maybe a leaf footed bug…if I was patient enough I could see what hatched but that was outside my time box).

(To be continued tomorrow…)

Belmont in January 2019

/

Last week, I attended a lecture for Howard County Conservancy volunteers at the Belmont Carriage House – arriving early to walk around a bit before the lecture. There was still quite a lot of snow on the ground.

2019 01 IMG_1257.jpg

I stayed on the cleared roads until I made the trek up to the old cemetery.

2019 01 IMG_1264.jpg

The old tulip poplar looks even more ancient in the winter with all the hollows and bark injuries more clearly visible. It had a lot of seed pods from last season just as the younger trees do.

2019 01 IMG_1272.jpg
2019 01 IMG_1276.jpg

One of the people I was hiking with pointed out an ash tree on the Patapsco Valley State Park side of the cemetery that had evidence of emerald ash borer (the lighter color on the bark). This tree will have to be cut down before it falls on the cemetery taking down fences and stones.

On a positive note – the hemlocks in the cemetery seem to be thriving. A few years ago they were infested with wooly adelgid but they were treated and it seems have saved them.

The wind must have ‘pruned’ the holly in the cemetery. A branch was draped from one of the headstones – no footprints in the snow around the headstone.

2019 01 IMG_1275.jpg
2019 01 IMG_1286.jpg

There were lots of deer tracks in the snow as we walked up to the cemetery and back. We didn’t see any rabbit tracks. Maybe a coyote?

We circled back along the row of white pines. The snow stands out even on a very cloudy day.

2019 01 IMG_1291.jpg

It was time to head back. I stopped near the mailboxes to take a picture of the pond with the bald cypress standing just to the left of it. It does have a classic cypress shape but if I wasn’t familiar with the tree, I’d have to hike down to the pond and see the cypress knees that surround it for a definitive identification.

Mt Pleasant in January 2019 – Part 2

/

Continuing the images from last week’s hike at Howard County Conservancy’s Mt. Pleasant….

2019 01 IMG_1105.jpg

I noticed a bluebird box with lichen growing on its roof. I wondered how long the houses lasted. This one had a plaque below it saying it had been installed in 2009 so it’s held up for 10 years!

2019 01 IMG_1036.jpg

There was some farm equipment near the edge of a field – covered in vines. It must not have been used for at least one season…and maybe longer. Nature is taking over! I didn’t get close enough to determine what kind of vines they might be – mile-a-minute or oriental bittersweet (both invasive) would be a good beginning guess.

With the record amount of rainfall we got in 2018, there was a root ball of a tree that fell – probably last spring.  What a dramatic change it must have been for the organisms around the roots before it fell…there would be a complex story to document different organisms came along after the tree feel and the elements alternatively dried out and filled in the hole (with water or soil washed into the hole). Nature is always in motion!

2019 01 IMG_1084.jpg

A beech tree had been cut down and the big logs left in place.  Maybe the tree had fallen and was cut up to clear the trail or maybe it was a standing dead tree that was cut before it could fall. The center was rotting. The beech bark looks so smooth from a distance but often looks wrinkled upon closer inspection.

Ranger, the barred owl, is back in his quarters near the nature center. He seemed very calm as we hiked by. There aren’t school fieldtrips with lots of students to crowd around his space during the winter; it’s easier for him to be Zen.

It was good to be back at Mt. Pleasant for a hike…maybe I’ll go again sometime with my husband…wear boots that can get muddy and hunt for skunk cabbage peeking through the muck.

Winter Walk in the Neighborhood - 2

/

I noticed a lot of mud as I walked in our neighborhood. Some of it was on the sidewalks – not something I’d noticed in previous years. 2018 was a record rain year for us…and we’ve continued to get rain in the first part of 2019.

2019 01 IMG_0903.jpg

There is mud where grass used to grow under many of the trees.

2019 01 IMG_0910.jpg

Sometimes the trees would have made the area very shady before the leaves fell but most of the branches of trees along the street are trimmed high by the county so emergency vehicles can get down the street without being damaged. There is still a lot of bare soil under them.

2019 01 IMG_0912.jpg

I am already thinking about what alternatives I have for the area under our plum tree; since we have a challenge with deer eating tender plants, my first idea is to simply mulch out to the dripline of the tree.

A squirrel was rooting in a raised bed in one yard. He noticed me, but I was far enough away (using the zoom on my camera) that he continued his investigation.

Scientists Don't Stay for Long in Their Jobs Anymore: Study | The Scientist Magazine® - About half of scientists who enter a scientific discipline drop out after 5 years; in the 1960s, it was 35 years. We are probably training more people in science fields but many don’t stay in academia. This study used publishing records to determine if a person stayed ‘in the discipline.’ I’d prefer to see numbers of people that had careers in a STEM related field rather than just the one they trained in and find another metric than published papers to make the determination. There are a lot more jobs today where people use their science training that do not use ‘publication’ as a measure of success.

There used to be hemlocks

/
IMG_0931.jpg

We’ve lived in our current house for almost 25 years. The forest behind the house was one of the reasons we bought it in the first place; my office is the best room in the house because of the view from the window. Over the years the trees have grown – the maple in our yard acting as a foreground to the taller tulip poplars behind. There is a holly that is the only tree that keeps its green in the forest.

But it wasn’t like that in the beginning. The forest is growing on a slope…down to the Middle Patuxent River. You can see the sky through the trees because of that slope and because the hemlocks that used to grow in the forest are all gone. I remember seeing them in the early years; the trees seemed to have crows at the top frequently; I always thought there must have been crows’ nests in the hemlocks. But then West Nile Virus killed almost all the crows and wooly adelgid – I am assuming - killed the hemlocks.

I don’t know exactly when it happened, but the hemlocks are gone, and they won’t be coming back. The crows, on the other hand, seem to be rebounding. I have seen more each year for the past several years. Today I am missing the hemlocks.

Squirrels and our Bird Feeder

/

Back in December I hung some garlands of suet and seeds on our deck for the birds; the birds didn’t find them fast enough. We fed squirrels. Within a few days, all that was left of the suet and seeds were the twine garland, straw bows, and hulls.

We’ve always had squirrels in our yard but now – in January - they seem fatter than I remember. They like to explore our deck from the railing – probably hoping for more suet and seeds. I’m not providing more.

I have put out the bird feeder with seeds. It’s several years old and I only fill it in the winter. It is supposed to be squirrel resistant and it has proved to be effective in past seasons. I finally caught a squirrel in the act…and the feeder with its seeds won the round! It has springs that are pulled downward by the squirrel’s weight (not birds) and there are metal ‘flowers’ that cover the holes where the seeds are available. Note the top flange of the feeder is below cap on the top…that indicates that the metal mesh with roosts and flowers is pushed downward. No holes uncovered to the squirrel.

After the squirrel thoroughly explored all sides of the feeder, it jumped down and the springs returned to normal uncovering the holes to give birds access to the seeds. Good design!

Conowingo Dam

/

Back in December we made a trek to Conowingo Dam. The dam was generating electricity and the spillways were open. The water was high and moving fast. A rainbow formed where the mist kicked up from the spillway flow. Almost all the rocks where the eagles and herons normally perch were under water!

The bridge abutment where bald eagles perched during previous visits only has a few gulls and gulls were the only birds we saw in the river too. The river was so strong that the fish were probably not making it close to the dam (when they do – when the water is not as swift – they attract all the fish-eating birds like eagles and herons and cormorants).

There was debris on the few rocks that were not covered by water and on the spit of the island containing the big electrical towers.

The lower part of the fishing park was closed because of high water.

I satisfied my self with some pictures of sycamores – seeds just above where we were standing and the white bark tracery on the other side of the river.

2018 was a record year for rain where we live and that is evidently true for much of the Susquehanna watershed as well. We’ll have to wait to go again when it hasn’t rained for a few weeks and the fishing will be good for the eagles at the dam.

Your guide to enjoying winter birds – It’s been so wet this year that we don’t have birds coming to our heated bird bath like we did last year. I put the bird feeder up a few days ago. Maybe we’ll start seeing more visitors.

Scientists Find Large Amounts of Methane Being Released from Icelandic Glacier - Yale E360 – A previous unknown source of methane…glaciers that are melting and happen to be covering active volcanoes and geothermal systems are probably all releasing methane. The gas is produced by microbial activity. This extra methane is not factored into current climate change models.

YE Thinking: Favorite Images

/

Looking for a way to summarize my year in pictures for this last post of 2019, I selected 3 favorite photos from each month – not an easy task for me. Many of them are from at home…some from other places close to home…then Socorro NM and Carrolton Tx. It’s been a good year! Enjoy the slide show….celebrating 2018!

Three Water Birds at Centennial Park

/

Last week my husband wanted to try out some new camera gear and decided to do it at Centennial Park. I tagged along to do some photography myself.  The lake is settling into winter.

I saw three birds on the water.

Canada geese were the most numerous although still a smaller number than I often see. The water was high in the lake and   the stone jetty near the boat launch (closed for the winter) was partially submerged. A goose stood on one – like a game of ‘king of the hill’ with the other geese.

There was a female bufflehead was periodically visible. Buffleheads are diving ducks that are very hard to photograph while they are feeding.

I managed to capture a sequence of the bird just after it surfaced…and then it dove again!

The third bird I saw on the water was a female common merganser. This bird was not feeding but quickly swam further away than I could follow with my zoomed lens.

That was it – less that a dozen Canada geese and then two lone ducks!

Walking back toward the car, I photographed some old birds nest fungus. There were still some ‘eggs’ in some of them…but probably thoroughly dried out by now.

There was also a very robust lichen on a dogwood tree. With all the extra rain we have recently the lichens and mosses are bigger and brighter than usual.

Gleanings of the Week Ending December 29, 2018

/

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.

From High Above, A New Way of Seeing Our Urban Planet - Yale E360 – Cities – growing and growing. It is mind boggling that urban population has grown from 751 million in 1950 to 4,200 million today.

How changing labs revealed a chemical reaction key to cataract formation: Researchers studying eye lens find a new function for a protein previously thought to be inert -- ScienceDaily – Learning more about the chemistry behind cataract formation….not a treatment yet but better understanding can be the path toward slowing or more targeted treatment of cataracts.

Curious Kids: What are some of the challenges to Mars travel? – A series from The Conversation (in Australia) for children…but interesting to adults too. Kids ask the best questions!

A DOZEN WAYS FAMILIES CAN #OPTOUTSIDE EVERY DAY OF THE YEAR | Children & Nature Network – I’m on a role with the child focused gleanings right now…I would add to the list: find easy access natural spaces (near where you work or live) and visit them as often as possible.

VIDEO: We Hope Your Day Is As Great As This Snow-Loving Panda’s: NPR – Pandas are such a visual treat. This is Bei Bei at the Smithsonian’s National Zoo back in November.  My husband and I missed the snow (we were in New Mexico).

Top 25 Wild Bird Photographs of the Week: Owls – National Geographic Blog – 2018 was my first sighting of barn owls in the wild…awesome.

Ragweed Is on The Move – National Geographic Blog – Not such a big change in the south….in Kansas City the season is prolonged by 23 days. For those people allergic to ragweed…that is a miserable trend.

Some health related posts: Blood pressure: Early treatment advised by US guidelines has no survival benefits -- ScienceDaily and Your heart hates air pollution; portable filters could help -- ScienceDaily – At least the second one was actionable; I now have a portable filter in my bedroom and I think it is reducing my cat allergy – maybe more.

Aerial photos of U.S. national parks from space – I love national parks. Everyone I have been to has had something spectacular to offer. It’s sad that they are all mostly closed (if the bathrooms and visitor centers are not open….they are closed) for this week (partial government shutdown).

How do different light bulbs work? – in C&EN | Compound Interest – Light bulbs have changed a lot during my lifetime. Hopefully now we are on track to have bulbs that are closer to the natural sunlight spectrum so that the light does not cause eye or sleep problems.

Zooming – December 2018

/

It’s been somewhat cold this month – but no snow yet. I’ve enjoyed photographing our transition to winter using the zoom on my camera to set the frame of the scene and/or to enable me to stay out of the mud (we’ve had lots of rain) or indoors and warm. There is still a little green left…and the sky sometimes seems brighter when its clear and cold. Enjoy the December 2018 Zoom slideshow!
