Festival of the Cranes – part 5

November 23, 2018/ Gwen Morrison

On the third day in New Mexico, I had signed up for a morning of Point and Shoot Photography at Bosque del Apache. It was a 6 AM start so the sun was just beginning to come up.

The snow geese were spooked before sunrise and took off. I took a video but otherwise just enjoyed the drama of a lot of birds taking flight at the same time.

It was a time of color and silhouettes.

The light got warmer as the sunrise progressed. There were cranes overhead and I like the silhouettes against the brightening sky. I was experimenting with the ‘sports’ setting on my camera – good for bodies in motion…including birds.

A little later but still early enough to have great morning light, we saw a small group of cranes and I took multiple series as parts of the group took flight. It’s interesting to see how they move their wings to life themselves from the water; the powerful first strokes are different than the way the wings move once they are aloft. I’ve included 5 sequences with this post. This experience was probably the highpoint of the morning for photography.

Continuing around the wild life loop we spotted a killdeer near the edge of a pond…enjoying a bath and the looking around the debris for breakfast.

The highpoint for birding was the snipe that I finally managed to see. They blend in with their surroundings!

Festival of the Cranes – part 4

November 22, 2018/ Gwen Morrison

Our first day at the Festival ended with a program about owls and then going out into the Bosque del Apache Wildlife Refuge to look for owls along the wildlife loop. Our guides managed to help us see three species: western screech owl, great horned owl, and barn owl. I didn’t take any pictures and am waiting on my husband to process his to (maybe) write a post about the experience. The barn owls in flight over the field (beside the road where we were standing) were the high point of the evening.

I was glad our field trip for the next day was not an early morning. We got to Sevilleta National Wildlife Refuge in plenty of time for our 8AM start. There were screwbean mesquites growing near the entrance of the visitor center. For some reason, I had not noticed this type of mesquite before; the seeds are quite different from the mesquites I grew up with in Texas!

The field trip was to a part of the refuge not open to the public. It turns out that the majority of Sevilleta is used for research. There is no wild life loop road and the part we would see during the field trip is not directly connected to the parcel that has the visitor center and refuge headquarters. The field trip group headed out in three refuge vehicles – down a highway and across some private land. As soon as we went through the gate to the refuge land the increase in vegetation was obvious. It’s still a dry place.

Horned larks flew up along the road as our vehicles proceeded down the road. There was a solanum species with their tiny fruits.

Someone with sharp eyes spotted oryx (gemsbok) in the distance. They were imported from Africa to White Sands Missile Range in southern New Mexico and their numbers have been growing in New Mexico (they escaped the missile range). Their numbers seem to be stable on the refuge.

2018 11 IMG_3231.jpg — We stopped to hike through a small canyon where sandstone that contains underground water abuts harder rock – forcing water to the surface – until the harder rock ends and the water goes underground again. I managed an identification-level picture of a Townsend’s Solitaire. There was a thin layer of ice on the water. The water was trickling through underneath.

Along the road, we stopped for birds. Most of the time I just got to see them through binoculars. I managed to get a picture of the Mountain Bluebirds

And several of a Loggerhead Shrike – one with prey. Later in the field trip as we drove along the barbed wire fence, we saw desiccated insects pinned to the barbs by shrikes.

A little further along there was a Canyon Towhee in the top of a cholla.

I couldn’t resist photographing the cholla!

A herd of pronghorn were just white rumps running away at first but then they turned and raced the vehicles. They would turn and cross the road in front of the caravan – forcing it to slow or stop until they crossed. Then they would run beside us on that side of the road before they crossed again. It seemed to be a game and only the pronghorn knew the rules. We all wondered whether it was the youngest in the group that decided to run…the dominant male was usually close to the back of the group!

We stopped at another canyon for another hike. It was drier although during the monsoons there would be water flowing.

The refuge staff has converted older style drinkers which worked for deer to shallow pools to work for other animals as well. The water pump is powered by a solar panel and there is a camera to document visitors.

We returned to the visitor center a little before 4. It was the only day of the festival that I got my 12,000 steps!

Festival of the Cranes – part 3

November 21, 2018/ Gwen Morrison

We made our way to the Bosque del Apache National Wildlife Refuge Visitor Center after the fly out. It was still a very cold day. We looked around in the visitor center and bought sweatshirts – giving ourselves another layer for later in the week – and then watched the red wing blackbirds near the feeder in the Desert Arboretum nearby.

There were still a few cottonwood leaves that had not turned brown.

The saltbush was thick with seeds.

We decided to take a turn around the wildlife loop. We saw quite a few Northern Shovellers

And coots.

My favorite water birds of the day were the pintails.

There were crystals still prevalent on vegetation; it was colder than it looked.

The day was sunny – the sky clear blue – typical New Mexico in winter.

Startled snow geese filled the air periodically. I took some sequences later in the week…so more to come about them in subsequent posts.

November 20, 2018

Festival of the Cranes – part 2

November 20, 2018/ Gwen Morrison

Our first morning at Bosque del Apache National Wildlife Refuge was before the festival officially started. We got up early to travel from our hotel to the ponds along the road just before the visitor center before dawn --- to see the fly out of sandhill cranes that roost there overnight. It was the coldest morning of the week! We bundled up with lots of layers (included snow pants), foot warmers in our boots, and handwarmers inside our gloves. I had a scarf with a hood and then the hood from my fleece too. We managed but I noticed frost forming on the head of my tripod where I breathed while I was taking pictures! I took pictures of a tree on one end of the pond that I remembered from 2016. The tree glowed with morning early light.

Some of the birds were standing on mud….others on ice. I noticed one juvenile (the bird does not have its red patch yet) on ice that quickly stood on one leg. I lost track of the bird in the moving mass of birds, but I wondered if it changed legs after a time…to let the other one get warm.

I took a series of pictures of birds landing and picked the two best sequences. It is interesting how they use their wings to soften their landing. The few birds that landed must have taken off a short time before from another roosting site. This is the first sequence.

And the second.

Some of them seem more alert than others. I like groupings where it is easy to see the iron dust they have on their feathers from their nest sites in the far north. In this picture there are the birds alert, sleeping, and preening….all close together.

The fly out is all about the cranes taking off. Again – I picked two sequences. They don’t go all at once…but in small groups. The power of the first few wing flaps – to get them off the ground – could be heard across the small distance through the cold air.

And then they are in sky heading to the fields where they feed during the day.

Cranes are paired for life, so it is not unusual to see pairs.

Once the sun was up it was easier to see that the shallow pond was more ice covered than water and how some of the cranes looked so much shorter…but with the large body of sandhill cranes. The morning color of the ice…not the golden from sunrise…is a metallic blue.

I started to look more closely at how the cranes were managing to walk on the ice. They did a little sliding but seemed to prefer taking off from the ice rather than the water.

Just before we left, I took some pictures of the frosted vegetation.

A cold morning…but a good start to our week in New Mexico.

Festival of the Cranes – part 1

November 19, 2018/ Gwen Morrison

We enjoyed our second Festival of the Cranes at Bosque Del Apache National Wildlife Refuge near San Antonio NM last week. Registration opened in early September and we decided quickly on the sessions we wanted…were early enough to get into them all. My criteria for sessions was: 1) something that we couldn’t easily do on our own or 2) a topic new to us or 3) something we enjoyed so much last time that we wanted to do it again!

A few weeks before our departure, I started a packing list color coded by packing location and then marked off as it was packed.

We knew the early mornings to see the fly out of the snow geese and cranes would be very cold…so lots of layers and hand/foot warmers. There were several days that we needed to carry lunch so we took an insulated bag. There was camera gear too; the tripods were in the checked bags – cameras in the carry on. I took three pieces of luggage: a suitcase that would be checked, a rolling backpack, and a duffel. My husband took four (two that were checked).

We didn’t forget anything…still have some ideas to do better packing next time.

I’ll be posting about the festival over the next few weeks. I took over 5,000 pictures in all because I set my camera on continuous shooting to capture motion (and I took some video too).

3 Free eBooks – November 2018

November 18, 2018/ Gwen Morrison

It is so easy to find books online these days. More institutions are scanning their older collections and Internet Archive is the access hub for accessing many of those scanned collections. Many books that would have been hard to find because they are out-of-print are now available in digital form.

Matz, Friedrich. Art of the World: Art of Crete and Early Greece, The prelude to Greek Art. New York: Crown Publishers. 1962. Available from Internet Archive here. A little dated (lots has been discovered and/or figured out since the 1960s), but the pictures are great. I loved the small stone jug. The text said it was probably stalactite. It was found in eastern Crete.

We are traveling back from New Mexico today…having enjoyed our second foray to the Festival of the Cranes at Bosque del Apache National Wildlife Refuge. Keeping with that theme – there are two books on my favorites list for this month that are related:

Johnsgard, Paul A. Sandhill and whooping cranes: ancient voices over America’s wetlands. Lincoln: University of Nebraska Press. 2011. Available for checkout from Internet Archive here.

2018 11 ebook3.jpg — ERIC. ***Wildlife of New Mexico: A Coloring Book***. 1986. Available from Internet Archive here. There are 31 animals pictured along with a map of their range when the book was published in the 1980s. The javelina must have expanded its range since it is now seen in the refuge which in south central New Mexico. But the highlight of the festival – always – is the sandhill cranes.

Field Trips in the Rain

November 16, 2018/ Gwen Morrison

Last week, I volunteered for two elementary school hiking field trips at Howard County Conservancy’s Mt Pleasant Farm….and it rained both days! On Monday it was kindergarteners and the ‘hike’ was shorted from 40 minutes to 20 minutes and accomplished in mostly the nature center. We started out on the terrace above the nature center looking out over the Honor Garden…talking about trees with leaves (and looked at leaves on the ground). Then we walked quickly around the front of the building to get to the nature center…and were wet enough already. Inside the nature center there were animal skulls and pelts…seeds and leaves…preserved insects…

When I talk to kindergarteners about tree cookies, I take time to explain what they are…and that they are not to eat! We count the main rings on the Royal Paulownia and then note that the other trees grow more slowly. My favorite is the dogwood because the rings are not as regular the other samples. The children are always enjoy learning about sugar maples…and maple syrup.

The rest of the time that would have normally been hiking was spent observing and hearing about Ranger, the barred owl.

On Friday, it only sprinkled a little on the first hike with second graders while we were out and about in the meadow. It was a very cloudy day.

During the second hike, it started raining. The children were dressed for the weather and more than half of them had umbrellas. We were in the meadow collecting and analyzing soil samples when it started raining. We decided we’d done enough samples and went to learn about the rocks by looking at an old stone wall. We started making our way back to the nature center by way of the goat and chicken enclosures…noting what the animals were doing (both enclosures have shelters and that’s where the animals were…out of the rain). We stopped briefly at the old stump in front of the farm house and discovered a snake skin fragment. Then we headed in to the nature center to see the living black rat snake (Onyx), a snake we see frequently at Mt Pleasant. They were ready for lunch too!

These were my last elementary field trips for the fall season. Even with the challenge of rain, they were good experiences…for me and for the students.

Sunrise and Sunset

November 15, 2018/ Gwen Morrison

One day last week I had serendipity photo ops first thing in the morning and just as the day was ending. In the morning I looked out the front of the house and saw three deer munching on the day lily leaves around our oak. By the time I got my camera, there were only two left. I trimmed the leaves more than a month ago as they began to look ragged and was surprised that they grew back. They are probably some of the most tender green leaves around right now. The day was cloudy and wet so even though the sun had been ‘up’ for about an hour, it was still relatively dark.

2018 11 IMG_3115b.jpg — Near sunset I noticed the color reflected on the clouds. They were moving rapidly so the shapes were changing. Our sycamore was already in silhouette with the vibrant color in the background.

A few minutes later the clouds still looked very orange. I zoomed to some distant tulip poplars that still had a few leaves.

Back to our sycamore in silhouette – the cloud has the shape of some creature with two big eyes and a toothless mouth…maybe a little like Jabba the Hutt.

o 2018 11 IMG_3115f.jpg — Then the color was down in the trees. We don’t have a clear few of the sunset since there is a forest to our west. It was a nice end-view for the day.

A few minutes observing…witch hazel

November 08, 2018/ Gwen Morrison

On a very wet morning earlier this week – I arrived at Howard County Conservancy’s Mt Pleasant Farm before a field trip with 1st graders and spent a few minutes observing witch hazel. There is one that I knew was blooming close to the Gudelsky Center entrance. It’s a low growing tree; in a forest it would be in the understory. This time of year, the leaves are yellow.

The flowers have petals that look like curly streamers coming out of the center part of the flower. On this plant they were pale yellow.

I kept by cell phone pointed downward to keep any rain from getting on the lens of the camera. It was raining enough that I needed to dry off the front of the cell phone as I walked inside.

Hiking with 4th Graders at Belmont

November 05, 2018/ Gwen Morrison

Last week I spent a morning hiking with 4th graders at Howard County Conservancy’s Belmont location. The theme for the hike was how the land has changed from it was all a forest 300+ years ago…to the way it is today with emphasis on the impact of our development of farms and factories…streets and homes.

I arrived early to help with set up. I carried a bag with materials for the terrain model to the table mid-way along the hike and then carried the other bag into the forest for the students to compare aerial photos of the Belmont area. I took some pictures since I knew once the students arrived I wouldn’t have time for more – I am totally focused on the students while we hike. Some areas in the forest have deep leaf litter and would soak up a lot of water before the water would run off…and right now there are some leaves that are still colorful too.

Coming out of the forest I took a picture of the Belmont cemetery and the row of white pines. I took my hiking groups to the side of the cemetery and talked about the ground penetrating radar that was used a few years ago finding graves under the ground within the cemetery even where there are no markers and also where we were standing outside the fence (lot’s of fun to point out on a Halloween hike) but the conversation also included the idea of shifting of sediment and deterioration of grave markers that might have been made of wood. The pine needles that have accumulated over the years under the pines make the ground feel spongy; that surprised some of the students….and that area would soak up a lot of water just as the leaf litter does – like a sponge.

There was a terrain model that we poured blue liquid over to represent the normal river level…then more blue liquid to be a minor flood (houses nearest the river wet)…up to the level representing the 1868 flood which washed away Elkridge Landing and parts of Ellicott City. The mills never recovered, and towns ceased to exist. The students were surprised to learn that the flood experienced by Ellicott City in 2018 was not that much below 1868 and it was higher than the flood caused by Hurricane Agnes (1972) in Ellicott City.

Overall – it was a great day for a fall hike with 4th graders!

BioBlitz with 7th Graders

November 04, 2018/ Gwen Morrison

I spent two mornings at Howard County Conservancy’s Mt. Pleasant with 7th graders for a BioBlitz.

Both days were cool and a little breezy. I arrived early enough the first day to take a few pictures of the fall gardens (in the calm before almost chaos)

And to look at the Green Infrastructure Network map again….enough to locate the approximate location of their school and think through how to talk about hubs/corridors in the county.

2018 10 biobli2.jpg — I had 11 students and a chaperone for about 2 hours and we found quite a lot. The most exciting – for me and the students on the first day – was a spotted salamander when we rolled over a log.

The brightly colored shelf-fungus and a wolf spider were good finds too.

On both days – one of the students borrowed my macro lens and became a specialist at getting macro pictures. Overall – the students handled being a little cold very well and stayed focused the BioBlitz for most of the two hours.

Milkweed Seeds

November 02, 2018/ Gwen Morrison

I cut the milkweed stalks in my yard down before they could produce seeds; my stand is big enough and my neighbors might not appreciate milkweed coming up in their yard. I was hiking recently in the Middle Patuxent Environmental Area (hiking back from the river after a stream assessment with high schoolers) and spotted some seed pods with fluffy seeds emerging. We’d had some dry days and the white fiber parachutes were carrying seeds away with every breeze – unless they were still matted inside the split pod.

Milkweed pods are one of my favorite subjects for photography in the fall. The bright white fibers draw the eye in the browning meadows.

Hopefully all these seeds flew away before the rains later that afternoon. Rain tends to destroy the parachute so the seeds are stuck either in the pod or in a soggy mass on the ground.

Milkweed also comes up from the roots so even if these seeds don’t find a way to grow, the stand will be denser next year with plants coming up from all along the roots already there. I noticed some young plants near the stand and wondered if some of the warm days we had in October prompted the plants to send up spring-like shoots.

In the Middle Patuxent at MPEA

October 29, 2018/ Gwen Morrison

It was a cold morning last week when I headed out at dawn to help set up for another Middle Patuxent stream assessment – this time at the Middle Patuxent Environmental Area which is upstream from the other Middle Patuxent field trips I had done this fall. It was a field trip that had been canceled previously because of high water (see the post about hike I made that day).

The day was cloudy but dry. I enjoyed the hike down to the river.

The water was low enough that we could walk across near one of the riffles without jumping from rock to rock. I was wearing two pairs of socks to fill out my boots and keep my feet warm. My table got macroinvertebrate identification (after we captured them) was set up on a gravel island in the middle of the river. The other two were on the bank further downstream.

Mayfly larvae were the more numerous critters we found – all sizes. There were numerous good photos taken with the macro lens by the students.

But the highlights of the day were two larger critters. The crayfish was large enough that it had to be in the plastic bin while the hellgrammite fit into the ice cube tray. Photos of these did not require the macro lens!

The group of 60 students managed reasonably well in the cold; it might have been a little warmer at the river level when we were dry. I realized as I walked back up the path afterwards that I was cold but for the two hours I was in the river – I was warm enough and overwhelmingly focused on the experience with the students.

Saturday Hike – Part II

October 26, 2018/ Gwen Morrison

We started down from the Howard County Conservancy’s Belmont Carriage House shortly after 10 AM with 21 hikers. I wanted to make good time for the downhill part of the hike to the Patapsco River in the Avalon area of the state park. I didn’t stop for any pictures. Until we got down to the river.

The water was cloudy with silt and the gravel bars that used to be in the center (where tiger swallowtail butterflies liked to puddle in the summer) were gone. The high volume of rainfall has swept them way. The shallows don’t look so shallow any more.

2018 10 IMG_2991.jpg — The paths were muddy and sometimes slippery with wet leaves. The rain from the night before was still running off. There were two downed trees across the trail at one point…the leaves on one still looked fresh – like it might have fallen the night before. It was easy enough to go under them rather than over.

We’d had enough dry days that there were some noticeable shelf fungi but none of the brightly colored ‘new’ ones that appear after several days of rain.

There was a light coating of leaves on the forest floor but a lot of green too.

There were more signs of trees that had fallen recently. I zoomed in on part of this one when I saw a funnel spider web that looked a lot like an owl!

We came out through the stand of big leaf magnolias and into the trail beside a hay field and thne were within sight of the carriage house shortly after noon. I had my 12,000 steps for the day!

Saturday Hike – Part I

October 25, 2018/ Gwen Morrison

2018 10 IMG_2984.jpg — Last Saturday, I lead a hike from Howard County Conservancy’s Belmont Carriage House down to the Patapsco River. It was a cool gray morning – a good day for a fall hike.

The starlings and male brown-headed cowbirds were busy around the carriage house when I arrived.

I noticed that the pods on the butterfly weed had opened but the seeds were still tightly packed inside. Perhaps the rain has come frequently enough this year that the white fibers haven’t dried out enough to become the parachutes for the seeds.

That was the calm before the hike. The list of people that had signed up was long – over 50 people. But only 21 showed up. That was large enough and I was glad that another volunteer was available to bring up the rear on the way down and be at the front for the uphill trek.

More about the hike itself in tomorrow’s post.
