Gleanings of the Week Ending May 12, 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.

Why I Speak Up for Science – National Geographic – A short piece about the need for science in everyday life….why science is important for everyone.

From property damage to lost production: How natural disasters impact economics -- ScienceDaily – The economic impact is more than just a single point of property damage and lost production…there is a ripple effect that can increase the overall impact significantly over what insurance covers and it beomes a very complex problem to estimate.

European Union Bans All Outdoor Uses of Neonicotinoids - Yale E360 – Shouldn’t we in the US be at least this concerned about the health of bees and other pollinators? Why have we not done more to curtail the use of neonicotinoids?

US gains in air quality are slowing down: New study indicates challenges of meeting ozone goals -- ScienceDaily – I live in an area that has an increasing number of ‘code red’ days (high ozone). This study indicates that emissions from cars and power plants are understood well enough…but not other sources and that is probably why the trend toward better air quality is slowing down.

BBC - Future - How prison changes people – Evidently the personality change that dominates is an inability to trust others….but there are other common changes as well. Prisons almost seem design to change personalities for the worse.

City upbringing, without pets, boosts vulnerability to mental illness -- ScienceDaily – We need to figure out how to make cities a healthy place for everyone --- including children.

BBC - Future - Why pristine lakes are filled with toxins – A study done on Lake Geneva revealed cadmium, mercury, lead…sometimes in high concentration…from decades of plastic build up in the lake. Other studies of the microplastics in the water (and in water that has been processed for drinking) and then beer and honey from the area. Lots more research is needed on the impact to wildlife in and around the lake.

Brookside Wings and Wine

Earlier this week we attended an evening event at Brookside Gardens that included wine tasting and appetizers in the non-butterfly end of the conservatory building….then watching the butterflies respond to the sun sinking to the horizon.

When we first entered, the conservatory seemed calmer. The zebra longwings – and other butterflies – were beginning to find a roosting place in the fichus tree.

Others were on the walls or ceiling of the conservatory. I’m sure there were many that found a place in the foliage where I didn’t notice them.

There were two flowers on the passionflower vine that is the food plant for a couple of the longwing butterflies; there were no butterflies around it.

Just before sunset, the owl butterflies became more active – many dances through the air. I was waiting for the male cecropia moth that has emerged from its cocoon last Sunday to fly from where it had been hiding in the fichus tree all day. But it stayed where it was. These larger moths do not eat as adults so maybe there was no pheromone in the air of a female cecropia moth…and he didn’t feel the need to move!  I contented myself with a zoomed image of it through the foliage.

Clearwing Butterfly

Some butterflies do not have scales…or have very few of them. There are a few specimens in Brookside Gardens’ Wings of Fancy exhibit and I’m always thrilled to see them. I rarely spot them on my own and most of the time I’m busy with my volunteer job as a ‘flight attendant’ so I can’t take pictures. Recently I was walking around the exhibit – not volunteering – and I had my camera and a tripod. There was a school group visiting the exhibit and they’d spotted a clearwing!

The butterfly was focused on breakfast of nectar from some white flowers (the proboscis was not rolled up between flowers….the insect was hungry!) so was staying put long enough for pictures.

The ribs that provide the structure for the wings are more obvious when the wing is clear. In the case of this butterfly they are a metallic copper color. Sometime that color is reflected in the thin membrane that is the wing.

There do appear to be a few scales on this time of clearwing – on the upper edge of the wing…some white and copper color.

Seeing a clearwing is one of the things that makes a walk in the exhibit special.

Macro Photography with a Smartphone

Before my second shift at Brookside Garden’s Wings of Fancy exhibit, I spent a few minutes doing some macrophotography with my Smartphone. I ordered a clip-on macro lens from Amazon last fall to use to photograph macroinvertebrates but haven’t done a lot of other photography with it until now.

Brookside Gardens is a great place to experiment. There is so much in bloom right now including the buckeye near the conservatory. The flower has a very odd shape through the macro lens (it looks like it has Mickey Mouse ears!). Even the tips of evergreen shrubs become something unexpected.

The center of the dogwood bloom is a riot of shapes. I’m going to photograph them again next time I go to see how it changes as the seeds start to develop.

Dandelion seed puffs are recognizable.

Just about any flowers are good subjects for macrophotography.

I ran out of time in the garden. My shift was beginning. I got one last picture just before the first visitors came into the exhibit – a spicebush butterfly egg on spicebush leaf. It looks like a very tiny pearl.

Blooming Pathways

During the same walk where we saw tulips near the end of their time in the Brookside Gardens, We noticed a lot of other spring finery along the pathways.

I always look at the ginkgo tree near the conservatory; the leaves are unfurling, and the mail flowers are abundant. Multiple leaves come out from a single bud, so they look like clumps early in the season. As the leaves get larger the clumps overlap and are not as obvious.

 The azaleas are beginning to bloom. Bushes peak at different times. Some were still just buds last week. The flowers that are a mix of white and deep pink are probably my favorites.

There was a peony near the path…. lovely from every angle.

Dogwoods are blooming too. The tree is one of my favorites. We had a dogwood in our yard when we first moved to the east coast 35 years ago; that’s when I really learned about the tree…observing it throughout the year. The trees in our area now survived the disease that wiped out many of the trees about 10 years ago….and they are blooming robustly this year.

So -  the blooms will fade, and their will be even more abundant greens – all shades…deepening into the richness of summer.

Last Day for Tulips

Last week my husband and I walked around Brookside Gardens enjoying the tulips. Some of the early bloomers were past prime enough that the volunteer gardeners were taking the bulbs up from the beds. I will have to find out next time we go to the garden what replaces tulips.

Some were widely open, and I enjoyed the curls and graceful curves of the waxy petals. My favorite tulips are the ones that are mostly yellow…tipped with orange. The colors remind me of sunrise and sunset.

There were some hybrid tulips up near the visitor center that were catching the mid-morning sunlight. They had a stronger scent and I wondered if the original plants were more heavily scented that the hybrids that we plant now. Tulips have gone through extreme breeding; perhaps bloom shape, color and longevity are more important than the smell.

I enjoy them all as a fleeting vision of spring. We’re on to the next round of blooms.

Blemont’s Nature Place Space

I have been volunteering with the Howard Country Conservancy’s preschool programs at Belmont recently. The weather was a little cool for the first few weeks…but it’s warming up – a lot – this week.

The station I fill for most of the programs is about trees. We talk about trees growing from seeds and look at ones from trees around us like sycamore (pictured below), sweet gum, tulip poplar, and maple.

A new addition that the children enjoyed this week is a nature play space. There are still some features that will be added, but the preschoolers were excited to jump from stone to stone and to climb up onto the big log….all in the middle of the meadow where it was just warm enough for cabbage white butterflies to be moving about.

The joys of being outdoors in the springtime!

Backyard Walk – May 2018

Last month I posted about violets and spice bush. On an walk through the yard this week, I still say plenty of violets blooming and

The spice bush was beginning to unfurl leaves. I hope there will be some spicebush swallowtails around this summer to produce several generations of butterflies in our forest.

The maple seeds are drying and will swirl away from the tree soon. The black walnut is beginning to unfurl its leaves. There are multiple leaves that unfurl from the buds on the tips of the stems as well as along it. The bud scars from last year are often visible. The tree lags the tulip poplars leafing out.

The high point of the walk around the backyard was not actually in the yard…it was just into the woods: A Jack-in-the-Pulpit! There are so many invasive plants in the forest that I always am relieved when I find a native making it through another spring. I'll try to pick a good day to spray myself with insect repellent (to keep the ticks away) and walk back into the forest before the prickle bush gets too thick to look for more native wildflowers.

The sycamore buds have just pops…with leaves too tiny to be very interesting yet. I’ll save it for the June post.

Wings of Fancy – 1st shift

I had my first shift for this season’s Wings of Fancy shift at Brookside Gardens earlier this week. The exhibit is opening an hour earlier this year to take advantage of the morning temperatures. Visitors will appreciate that during the summer. Like last year – I took a short walk around the gardens before heading into the conservatory. The gardens are lush even with the variability of rain and temperatures so far this spring.

The azaleas are blooming but I decided to walk through the are where the tulips are blooming….lots of color on a spring morning. I walked fast because it was chilly at 8:30 AM (in the 40s and breezy).

I was in the conservatory waiting for the first visitors and decided to take a few pictures. I was surprise what I was able to do in 10-15 minutes! My theme was heads – eyes, antennae, proboscis, and papillae. I’m sure they’ll be many other butterfly pictures this season (the exhibit runs until September 16), but I’m pleased with my first batch. Hopefully a reflection of the happy place the exhibit creates comes through too!

Photography through a Window – April 2018

The juncos were in out backyard and frequent visitors to our feeder and birdbath at the beginning of the month…and then they left for their nesting grounds to north and west. We won’t see them here in Maryland until it gets cold again.

The big story of month for our backyard was more about trees than birds. The red maple bloomed and made seeds. I am watching for when the seeds helicopter away from the parent. Of course, some of our backyard birds (cardinals and goldfinches) were in tree for some of the pictures. They like to snack on the tender seeds.

The tulip poplar leaves are unfurling with the pods from last summer still holding a few seeds.

The sycamore is still looking very much like it has all winter; it is always one of the last to leave out.

The tree I haven’t photographed yet is the black walnut. I noticed last time I walked around that it had some leaves unfurling but it’s location requires that I walk to it rather than trying to photograph it through a window!

Zooming – April 2018

Zooming make the photograph in so many cases. I could never get the pictures of birds that I do without it…the birds would be long gone. This month the zoomed birds include: a great blue heron being very still, a bluebird showing his colors, a finch high in a tree at a Texas rest stop, a blow legged grackle, and ducklings.

I use the zoom for flowers to avoid stepping in flower beds – or mud – or simply because what I want to photograph is too high in the tree.

On road trips, the zoom helps with photography through the windshield (buildings and bridge abutment murals, for example)…and quickly framing a picture when I am hurrying to get back to the car and out of the weather.

The modern digital cameras with good optical zoom lenses…and image stabilization…a boon to photographers everywhere.

Ten Little Celebrations – April 2018

April has gone by very quickly…full of company and travel and the beginning of the spring volunteering blitz.

Six of the 10 little celebrations were experiences outdoors – typical celebrations of springtime everywhere:

• Blue birds and tree swallows were making their nests I the boxes at Mt. Pleasant in Maryland.
• There were ducklings at Josey Ranch Lake in Carrollton, Texas.
• An eared grebe at Hagerman National Wildlife Refuge near Sherman, Texas.
• Macroinvertebrates in the Middle Patuxent close to home.
• Spicebush in the forest behind my house and at Belmont Manor and Historic Park (both in Maryland).
• Deciduous Magnolias blooming at Brookside Gardens. Maryland got a freeze at the wrong time in 2017 and most of the blooms turned brown from the cold just as they were opening. It was a treat to see them again this year.

I celebrated the end of two long driving days between Maryland and Texas. Both were blustery and more traffic than expected. It felt good to be done!

My new iPad is something I celebrate every time I create another Zentangle with it! I a pleasantly surprised with how easy I made the transition from pen and paper tiles to digital.

I thoroughly enjoyed a meal at a Brazilian steakhouse – this time managing to savor the flavors and not overeating. I even topped off the meal with dessert!

Finally – the Watershed Summit where the high schools of the county presented their report cards to the county government for their steams and school yards – based on data they collected last fall. Each of the 13 high schools had 2 presenters. They all were so poised and organized. It was a double celebration: the environmental findings trending positive in most cases and the quality of the students in attendance. Both bode well for the future.

Hagerman National Wildlife Refuge in Spring

I visited Hagerman National Wildlife Refuge earlier this week. The day was too cold and too windy….but was the only one that fit it the schedule. I remembered to take pictures of the metal work near the visitor center.

In the garden near the front of the visitor center, I didn’t see any butterflies…but there were dried blooms from last season left on the trumpet vine growing on the arbor and a clump of bluebonnets (we’d seen larger patches as we drove to the refuge along the highway).

We decided to use our car and a moving blind and protection from the wind….making our way slowly around the wildlife drive of the refuge. There were not many birds but enough to make some photography attempts. The most unusual was a Eared Grebe in breeding plumage. Someone in the visitor center had commented about seeing a pair but we only saw one.

There were some American avocets a little too far away for a good picture on a cloudy day. They can be identified with the picture I took….and there is a Great Egret in the foreground.

There were also Snowy Egrets (black bill and legs, yellow feet).

Very far out in the water on snags were American White Pelicans and Double Crested Cormorants.

The Greater Yellowlegs was closer and intent on finding some lunch.

The Great Blue Herons were numerous and seemed to all have the blue topknot of mature birds.

We saw one turtle positioned for maximum sun (warmth) but there were probably more.

There were still some Northern Shovelers on the water; most of them have left for their breeding grounds in the north. A pair of Blue Winged Teals were hiding in the plants beside the road as we were leaving; they are close to their breeding grounds based on the allaboutbirds map…so might have just been making a last stop over.

I took a few shots of wild flowers as we drove out of refuge….just rolled down the window and used the zoom!

Not bad for a cold, cloudy day!

Carrollton Texas Yard

It’s a good time of year for gardens in Texas --- the weather has not gotten too hot. I like plantings around base of trees. They’ll go into the summer too.

The iris displays are at their peak right now. They still have a lot of buds so will be going strong for another week or two.

Josey Ranch Park in Carrollton, Texas

The baby ducklings I posted about yesterday were the spring highlight for me at the part….but I was pleased with other sites too.

The buttercups in the grass…and the serendipity of catching a butterfly in flight between flowers.

The male grackles were facing off…asserting their dominance.

There was a scissor-tailed flycatcher that posed on a post for picture.

I hadn’t realized how similar they looked to mockingbirds that are also in the area….except for the vary long tail.

I saw two pairs of ducks (other than the mallards) that are probably getting ready to leave for their breeding ground further north: gadwalls (photo is of the male)

And northern shovelers. Both were probably more numerous in the area a few weeks ago.

There was a squirrel that did not look happy for me to walking nearby as

An American coot that didn’t seem to know I was there at all.

My round-trip walk was about 2 miles…good exercise…and a good outing for some photography.

Ducklings

There were two cohorts of Mallard ducklings at Josey Ranch lake in Carrollton TX last week. I walked saw them on two different days – one group had 7 ducklings and the other 8. There are some larger turtles in the lake that might be a threat while the ducklings are so small – but the parents (sometimes with extra helpers) were attentive and keeping the ducklings in the shallow water away from deeper water where the turtle could pull them under.

Most of the time the ducklings stayed together. There were several instances that it appeared that the female was making sure all of them were still with her! There seemed to be more males that females around the lake and all the adults seemed to be near where ducklings were.

Enjoy the ducklings – one of the sure signs of spring!

Road Trip to Texas – Part 2

The next morning, we were up and having breakfast shortly after it the service opened at 6 AM. It was a cold start to the day – a frosty morning in Dickson Tennessee. The sun was just coming up through the trees we loaded the car and headed out about 6:30. We’d were already on central time so would not benefit from a time change on this leg of our trek.

The first rest stop was about an hour later. I cheered when the vending machines had my favorite caffeine drink (diet Pepsi). The day was still chilly but not frosty. The rose bushes at the rest stop were full of buds.

Our next stop was the welcome center after we crossed into Arkansas. It was a newer facility with some interesting architecture and posters; my favorite poster was the one of ‘mud bugs.’

We had a long wait on the highway that added more than an hour to our drive; a truck had lost part of its load and a crane had to be brought in to move it off the roadway. When we went by all the traffic was slowly funneled by on a shoulder. We recovered with a barbeque lunch near just before we got to Little Rock.

Then it was on to Texarkana and the welcome center for Texas. It’s a little tricky to exit the highway for the place…it was large with relatively few people around.

The next stop was the old-style Texas rest stop with tile mosaics unique to the place. The surprise of the stop was the historical marker; my sister recognized the name from her genealogy work!

The last stop of the trek was just before we entered the Dallas traffic…wanted to make sure we were in good shape for the final push to our destination.

Road Trip to Texas – Part 1

I drove from Maryland to Texas with my sister earlier this week….a 2 day trek. We left my house about 6:30 AM and headed west on I70 rather the dealing with the traffic around Washington DC. I am getting very familiar with the South Mountain rest stop since this is the route to the Pittsburgh and State College as well. This trip – it was in the low 40s and wet. The daffodils were blooming.

The next stop was for gasoline. The flowers in the wooden pot were past prime but I appreciated them anyway. The Prius was doing well although the wind was beginning to pick up and I was aware that I was gripping the wheel a bit too hard.

We had food for lunch in the car so used the stops for walking around. There were daffodils again at the next stop.

Finally, we got to Tennessee. The rest stops along the interstate have a log cabin side and rock cabin side. I like the rock side since they are rock from the immediate area.

We were making fast stops because the temperature was dropping. There was a dusting of snow along the highway between Knoxville and Nashville! The wind was gusting and made it feel very cold.

The last stop before we got to the hotel in Dickson, TN had a different kind of rock and a historical marker for Senator Albert Gore Sr…and the interstate highway system.

Tomorrow I’ll post about the second day of the road trip.
