Twigs and Witch Hazel

January 25, 2019/ Gwen Morrison

I have been looking more closely at twigs of trees recently and trying out simple dichotomous keys. As an example: here is one I looked at during a class on winter tree identification. Looking at the full branch – it was obvious that the leaf scars were opposite. Next, we needed to look at the leaf scars in more detail. There were hand lenses for everyone but I used my 15x lens clipped to my phone so I could share what I was seeing. The leaf scar was D shaped and had three bundles. And the new growth was red. We had to break the twig to smell it…its didn’t smell rank, so it was a RED MAPLE.

It turns out that multiples buds at the twig tip is indicative of maples and oaks…and that maples are opposite, and oaks are alternate. So – it’s possible to take a picture looking up into a tree and make a tentative identification. For example – this was a picture I took in my neighborhood with alternate branching and multiple buds at the end of the twigs – an OAK. I had been using the relative height of the trees in my neighborhood (oaks are taller) but this identification is better and maybe easier too for the street trees planted by the builder 25-30 years ago – oaks and maples.

I couldn’t resist taking a picture of the crumpled bark on the red maple twig. I wonder if they smooth out as the twig grows when the weather warms?

On a more colorful note: be on the look out for witch hazels. Some bloom in the fall but others bloom now. There is one at Howard Country Conservancy’s Mt. Pleasant location that I am watching. Hopefully bitterly cold weather will not damage the flowers that are beginning to unfurl.

Belmont in January 2019

January 20, 2019/ Gwen Morrison

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.

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

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_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_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.

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.

Snow Day

January 18, 2019/ Gwen Morrison

2018 01 IMG_1132.jpg — Last Sunday was a snow day for us. It had snowed all night and was still snowing when I got up. Our neighbor had a spotlight on and it illuminated the back of our house enough that my camera’s ‘hand held night scene’ setting was enough to capture the snow draped over pots and chairs on our deck. In the front of our house there was less light – but the oak near our driveway was visible in the darkness.

There was no sunrise color – the clouds were too thick – but the day brightened a little. Snow was accumulating on the bushes.

I went out to measure the depth of the snow about 9 AM; it was about 5 inches and snow was still coming down.

The day was brightening a little more.

We shoveled the driveway. The snow was heavy enough to stick together but not too heavy to shovel easily. I took a before and after picture.

I took a picture of the kokopelli metal sculptures dancing in a low pot on the deck from my office window

When we came inside my husband started a fire in the fireplace and I went out to skim the top inch of snow off a portion of our deck and into a big pan. I left it outside to stay frozen while I gathered the other ingredients for snow ice cream. I had purchased some French vanilla coconut creamer (sweetened) that substituted for the usual milk, sugar, and vanilla; I added the last of the peppermint candy chips I had bought before Christmas. The snow went into the biggest bowl I have and then the milk and peppermint candy mixture. My handheld mixer does a great job mixing everything fast enough that the snow doesn’t have time to melt. The color from the candy was my indicator that the ice cream was becoming thoroughly mixed. I had to add a bit more creamer because the snow was so icy; it looked crumbly instead of creamy.

Yummy! It was the best snow ice cream I’ve ever made! My husband and I had two servings each – ate the whole batch in one sitting.

Mt Pleasant in January 2019 – Part 2

January 16, 2019/ Gwen Morrison

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

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!

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!

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.

Mt Pleasant in January 2019 – Part 1

January 15, 2019/ Gwen Morrison

2019 01 IMG_0989.jpg — My first hike at Howard County Conservancy’s Mt. Pleasant was last week on a cold, blustery day after a night rain. We were prepared for the cold and managed to work our way around the muddy parts of the trails. The sun played hide and seek with the clouds. I was taking pictures of winter trees. I am very familiar with a black walnut near the rock wall on the meadow side.

The nuts on the ground all around it would give it away even if I didn’t know it was a black walnut. I am always amazed that the squirrels can get the shells open with their teeth.

The path along the wall was in relatively good shape – still mostly covered with grass. We didn’t go all the way down to the Davis Branch…but cut across the meadow mid-way down the hill.

We took the long way around to an overlook of the Branch since the lower trails were too muddy to attempt.

The water was not high, but everything looked wet. I was noticing the beech trees – easy to identify by their smooth bark.

One of the root balls that had been placed upside down in the restored part of the stream had been washed downstream by an earlier flood…and was still balanced where I’d seen it last fall. It will stay there until the next big flood. It had a collapsed pillow-like orange fungus growing on it.

2019 01 IMG_1040.jpg — A river birch is easy to identify with its curly bark.

As we turned back toward the nature center, I noted that one of the trees across the smaller stream had finally rotted enough to collapse.

The only ‘bloom’ I saw on the hike was the beginning of the witch hazel bloom on the tree near the farmhouse. The streamer like petals are still curled up in the opening flowers. I’ll have to remember to look at the tree every time I go to Mt. Pleasant over the next month or so!

Winter Walk in the Neighborhood - 2

January 14, 2019/ Gwen Morrison

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.

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

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.

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.

Winter Walk in the Neighborhood - 1

January 13, 2019/ Gwen Morrison

I took a walk in our neighborhood on the warmest day last week. It was a blustery day – felt more like March than January. I walked down to the storm water retention pond first. It still looks relatively barren but there is vegetation on all the slopes.

2019 01 IMG_0868.jpg — The cattails are beginning to repopulate the shallows. I wondered if there were enough for the red winged blackbirds to come back to the pond. Maybe more cattails will come up next spring from the roots already in the mud…if they aren’t drowned from all the rain we’ve gotten.

The wind was blowing oak leaves onto the water.

Younger oak trees often keep their leaves well into winter. Or course – every breeze takes a few more leaves away but there were enough left on some of the trees in our neighborhood to still use the leaf shape to say definitively – it’s an oak. The tree in front of our house retained it leaves did years ago but is now old enough that its leaves drop in the fall.

2019 01 IMG_0917.jpg — As I looked back along our street, I realized that the general way to tell the maples from the oaks planted along the street by the builder is to look at the height. The taller ones are oaks.

Shrinking of Utah National Monument May Threaten Bee Biodiversity | Smart News | Smithsonian – Grand Staircase-Escalante is home to 660 bee species, 84 of which live outside of protected land under changes. At a time when we know pollinators are under stress…one more reason why our Federal lands are needed as refuges from human activities that damage the environment.

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.

Conowingo Dam

January 06, 2019/ Gwen Morrison

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.

Brookside Lights

January 04, 2019/ Gwen Morrison

Last week, we managed to get over to see the holiday lights at Brookside Gardens. They are worth at least one evening walkabout between Thanksgiving and the end of the year. It’s a family tradition for many people in our area of Maryland. There are things that stay the say…some things that are new...every time we go. This year there was another frog sculpture (with a butter fly and little frog) in the visitor’s center; I hadn’t noticed it before.

The caterpillar tunnel was the same near the entrance to the gardens just outside the visitor center.

The spider web and rainbow with lightning and clouds with raindrops were also repeats from previous years.

I always like the dragon (mom and baby). In previous years they spewed smoke.

Another new display: saguaro cactus light shapes.

The butterfly and lights on a water feature (lights instead of water for the winter) were oldies but goodies.

I also like the spotlight on the sphere sculpture that I like so well during the day. The irregularities in the rock are more visible with the shadows. This might be my favorite picture from the whole evening!

I created a slideshow with my other favorites. I like the nature theme for the lights - flowers and moon and trees shapes, insects, tall stalks, a snake and ants and a fox, mushrooms. Sometimes I am not sure what it’s supposed to be…but it’s always fun to guess.

It’s also fun to listen to parents interacting with their young children. I noticed a toddler almost in front of us walking across the sidewalk; his father said “Don’t sit in the mulch” and the child promptly took a few more steps, turned around, and sat down in the mulch. He was helped up…dusted off in the back (it was cold so he was well bundled up). Everyone laughed…a good time!

Three Water Birds at Centennial Park

December 30, 2018/ Gwen Morrison

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.

YE thinking: Blog Evolution

December 27, 2018/ Gwen Morrison

2011 12 blog snap.jpg — My first blog post was back in November 2011. I recently went back to look at some of the older posts and did the mental exercise of noting what has changed…what has stayed the same. Some of the early posts started out with quotes like this one from the day after Christmas 2011. There was more text than pictures in those early posts.

The 10 characteristics of a matriarch…and me…haven’t changed. I’m more settled in all of them now than I was 7 years ago:

Past the drive to make a living. The prime drive to establish oneself in the world and make an acceptable home is probably from ages 22-55. It can vary but there comes a point in life where the focus on a career shifts to something else much more integrated with everything else life has to offer because the hard work has paid off and the prospect of doing something completely different can take precedence.
Children are living independently. Until ones children are living independently, you are a mother rather than a matriarch!
Healthy and full of energy. Matriarchs have retained their health through lifestyle choices and care for themselves. They often appear younger than they are because of their attitude toward life and their energy pursuing whatever interests them.
Understands herself better than earlier in her life. The changes that occur as children become independent and the long term career ends (usually intentionally) forces a period of contemplation about what is truly important for the next phase of life. The answers don’t particularly surprise our matriarch…she views the time to think about it to be the tremendous luxury of the in-between days.
Self-actualized decisions. As a teenager and adult, she may have followed the advice of her parents or mentors or managers. All that was good. Now she is much more in the mode of making her own decisions with inputs from others not being quite as important as they were earlier in her life.
Post-menopausal (i.e. past child bearing). The joy of not having a monthly rhythm…feeling great all the time!
Knows how to live within her means. Whatever her financial situation, she knows exactly how to make ends meet and sustain her home. After all – she plans to live to be 100.
Assertive. She is nice about it, but she is savvy and does not let people take advantage of her unfairly.
Lots of self-discipline. She gets up fairly early in the morning because she is enthusiastic about getting started on the activities of her day. Her rhythms of communication with the people she loves are consistent and thoughtful. The interests she develops are wide ranging and shared as she develops relationships with like-minded others.
Married. She is known for her long duration relationships….most notably a spouse…although it could be friends as well. If she is widowed she does not live in the past but she may not feel it necessary to form a new relationship that cannot rise to the same level of shared history.

I would add at a couple more characteristic based on my last 7 years:

Giving back. Matriarchs are always looking for ways they can be a positive influence in their community and the broader world through volunteering time (and/or money).
For the long term. At some point, taking a more strategic view of the world becomes easier. That translates into living my life thoughtful of what will continue after I am gone. It is the way of savoring the present cognizant of the impact on the future of people and the world.

The weekly gleanings posts appeared almost from the beginning but my picks have shifted a bit toward more visual and science rather than technology.

I started a monthly doodle post in 2012 then there was a lull after mid-2013 until I took a Zentangle class in January 2015 and started the month Zentangle post. Behind the scenes prep for the post changed over time from taking photos to scanning then to digital tiles on the iPad using the Apple Pencil beginning last spring.

Coursera came along not that long at a good time for me and I enjoyed courses that I’d not been able to take back in my college days. My posts about them started in 2014 and continued for at least 3 years. Now I am more focused on conferences and travelling than online courses…although I might go back to them at some point.

Photography has become a bigger hobby to me over the past 7 years and the blog is a major outlet for my images. When I travel – it’s always with a camera readily accessible. And then I have the illustrations for what I want to write about and a reminder of experience too.

Travel has always been good fodder from blog posts:

2011: road trip from Maryland to Arizona
2012: road trip to Shenandoah National Park in April, Tennessee parks in June, state parks in southern New York in October, Dallas in December
2013: Arizona in March, South Carolina in April, Norfolk and Richmond in May, Arizona in June, Utah in October, Florida in November
2014: Dallas in March, southern New York parks in May, Newport RI in late September, Chincoteague VA in November
2015: Tucson AZ in January, North Carolina wildlife refuges in April, Dallas in July and again in September, Staunton River State Park (Virginia) for star party in October, Hawaii in December
2016: Tucson AZ in January, eastern shore MD wildlife refuges in March, Dallas in April, Florida in September, Staunton River State Park (Virginia) for star party in October, Festival of the Cranes in NM
2017: Cross country from Maryland to Arizona with a stop in Dallas for my daughter’s conference, Dallas in March, Pittsburgh in March, Delmarva Birding in April, Dallas in May, Road trip from Tucson to Pittsburgh in June, road trip from Nebraska for solar eclipse in August, Staunton River State Park (Virginia) for star party in October, TX for Rio Grande Valley Birding Festival in November, Pittsburgh in December
2018: Dallas in April, Dallas in June, State College in August, Festival of the Cranes in NM, Dallas in December

I’m sure the blog will continue to change – nothing stays the same and we shouldn’t want it to.

Zooming – December 2018

December 26, 2018/ Gwen Morrison

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!

Travel Day

December 23, 2018/ Gwen Morrison

A week ago, I got up in Texas and got ready to fly home to Maryland. As I got my breakfast, I noticed that the sunrise was spectacular. I quickly grabbed my camera to take some pictures from the backyard. The colors were changing fast. There was a little breeze that caused me to notice the windchimes and I decided to take a silhouette of them with the colors of the sunrise in the background.

Looking back toward the house, there were some hazy clouds that reflected the color. What a great start to my last day in Texas!

My strategy for the trip was to pack small bags rather than large ones. I was flying on Southwest so there was no charge for checking two of them. I carried my back pack and tote on the plane. The tote was holding a red poncho that I wore on the plane (and is a good substitute for a blanket). The strategy worked well for this trip. It’s great to not have to lift heavy luggage.

It felt good to get home later that day. I always savor being ‘home again’ after being away for a week.

Josey Ranch Birds – Part II

December 21, 2018/ Gwen Morrison

There was finally another sunny day in Carrollton TX and I headed over to Josey Ranch Park again. I was lucky enough to arrive about the same time two women arrived with food for the birds. Two swans were at the boardwalk before the women could make their way from the parking lot to the boardwalk; the swans must recognize the signs of a forthcoming meal. The pigeons and seagulls flew in quickly.

After the crowd of birds gathered to enjoy the feast – the coots seemed to be arguing – chasing each other and churning the water. The northern shovelers in the background did not hurry over like the other birds.

How many birds can you identify in this picture? (see the bottom of this blog post for the most prominent ones). This is a good picture to see the relative size of the birds as well.

There are not very many mallards at the lake this time of year. The light changes the green coloring of their head; sometimes the feathers look black!

Lesser Scaups are more prevalent.

The Great Egret is there every time ago – must be a resident.

Pigeons are on the roof of the nearby senior center and library except with there is food! Iridescent neck feather and red eye – oh my!

The Northern Shovelers are not quite as numerous as the Lesser Scaups and they seem relatively used to people being about.

I managed to get a seagull taking off from the lake – watch the one to the center right.

Birds in the ID quiz picture: swan (partial) on the far left, Canada geese in the upper third, ducks with large bills and rust colored sides are male Northern Shovelers, ducks with light sides and brown heads (yellow eyes) are male Lesser Scaups, coot in lower right (black with pointy beak), pigeon (partial) on bottom margin, gull? Inflight in the upper left.
