A Few Minutes at Mt Pleasant

I went to Howard County Conservancy’s Mt. Pleasant for a couple of Winter Wellness presentations (for the HCC volunteers) on a cold bluster day. It had been over a month since I had been but it was not a good day for lingering outdoors – even though the sun was shining, it was not one of those ‘colder-than-it-looks’ days. All the leaves were blown off the deciduous trees and the flower beds were brown or very wilted green. The hay field to the left of the drive as I drove in had been cut and the round bales left in the field.

I parked as close as I could and took a picture of the farmhouse as I walked in. The big tree that previously hid the left side of the house was cut down in 2019 and the new walk was installed. It gives the area a more open – and formalized – look. The flowerpot people still look a little Christmassy…but at least the hats and scarves were staying in place even with the blustery wind. I took that picture on the way out.

Overall…it was only a few minutes outdoors – good bookends for the lectures.

In the Middle Patuxent River – January 2020

Last week I was in the Middle Patuxent River at Robinson Nature Center for the quarterly (winter) water monitoring. The temperature was in the 50s and sunny – an easier sampling than most years. I always like to take some pictures from right at or in the river. It’s a different perspective that being on a forest or meadow trail.

20200115_095557.jpg

I was the only one of the sampling crew with just boots….everyone else had waders. But the river level was not too high. I didn’t get water in my boots…and no one fell in either.

We caught a madtom (catfish) in one of the collection nets (collecting macroinvertebrates). We took pictures and let it go before we headed up the hill to the Nature Center.

In the lab, we divided the buckets of samples into plastic bins and we all started collecting macros from our bins and randomly putting them into the two partitioned trays.

20200115_120727.jpg

Then random numbers were drawn to determine the compartments we would id and count until we got to 100….and then we looked at what was left for anything unique. Almost everyone took a few pictures of macros. The most unique thing we found was a white worm!

This was the first time I participated in a winter monitoring and it might have spoiled me – being as warm as it was.

A Few Minutes at Belmont

When I got in the car to go to Belmont Manor and Historic Park last week, it was evident I hadn’t been there since November; it was so far down the ‘recent’ list in my navigation system that I switched to the ‘saved’ list! Once there I finished my errand quicker than expected so took a few minutes for pictures.

Inside there was Katrina, the diamondback terrapin. She was very active.

IMG_7152.jpg

Outside on the side of the building, there were the familiar signs.

The red maple planted by last year’s HoLLIE class looked healthy (red tinged twigs) – dripping from the mists that were swirling around.

IMG_7157.jpg

But the small birds that seemed to be everywhere were what drew my attention. I’d seen a mockingbird as I walked toward the building earlier, but the small birds moved around closer to the ground in larger numbers – in the leaf and brush – blending in. I managed to photograph one – song sparrows!

Future For Silversword Plants At Halaeakalā National Park Dark – Rare plants…have not recovered as well as the Nene (Hawaiian goose) – for several reasons. Plants around the world are having to adjust to changing climate and some will not be able to change fast enough to continue to exist in the same places…some may become extinct. I hope the Silversword survives.

Maryland State House Ceiling as Zentangle® Prompt

I am always noticing potentials for Zentangle patterns. An easy one was in the skylight at the Maryland State House (when we visited back in December). I made a tile without much thought about deconstruction. The stained glass ‘flower’ is was my primary interest.

2019 12 IMG_6705.jpg
2020 01 img246.jpg

I used a string to guide the pointed arc shape around each flower…then just make the curves. I filled in the spaces between the ‘petals’ to add some drama…and then it was just the tried and true Zentangle auras to fill in the rest of the space.

I did a simple step out of the way I deconstructed the pattern after I made the tile!

20200109_085037.jpg

Zentangle prompts are everywhere! I’ve been looking at books about ancient pottery recently….lots to patterns to glean from them. I try to limit myself to one of the ‘Zentangle prompt’ posts each month, but I am very tempted to do another this month.

Memorable Picture

I took this picture back in November. It is the side of the Missouri State University stadium. What do you think the image between the two columns represents?

IMG_6419.jpg

My mother glanced at it – thought it was a spider….but the logo is actually of a bear! It a rectangular clip of a squarish logo that is obviously a bear. But I can see how it does look like a spider at first glance….and that’s what makes the picture memorable. It draws me back to a moment in time on a cold November day, walking between the building and our car, noticing the fierce whatever-it-is, laughing. I took the picture just after my mother’s comment and we all pilled into the car. A happy time.

Touch Tank – January 2020

20191229_142539.jpg

I enjoy the volunteer gig at the Robinson Nature Center Touch Tank….getting more experienced every time I spend an hour there. The Discovery Room, where the touch tank is located, is full of activities for pre-school through elementary school aged children with the Touch Tank being available when there is a volunteer to open it.

There are two kinds of sea urchins: the slate pencil with spines that look like slate pencils from the 1800s and pin cushion with spines that are more prickles. Both names are somewhat historical for young children. Some have never seen a pin cushion! Even the adults haven’t seen slate pencils that look like the sea urchin. Everyone enjoys seeing how the pin cushion urchins ‘hide’ by holding shells and little hats to themselves. The pin cushion urchins can also hang on well enough to hang upside down for a little while on my hand…always a surprise to the children.

Sometimes the sea urchins attach themselves to something else – a rock or a conch. Do you see the pin cushion urchin on the back of the milk conch in the pictures below? The conch was on the move with eye stalks extended and vacuuming up its food from the sand.

20200105_134905.jpg

There are three conchs in the tank. The largest is usually the most active.

And then there are the sea stars. I like to look at them through the glass of the tank…with their suction-cup feet out and hanging on. I pick them up for the children to touch – back and front – but I like them better through the glass.

Overall, I am getting more comfortable with the animals in the tank and better at controlling the flow of people (children) around the tank. An hour at the touch tank is always an hour well spent!

Eastern Bluebird – January 2020

On the second day of the year, a male Eastern Bluebird appeared in our backyard. I saw him first near the bird bath. By the time I got my camera, the bird was in the sycamore…looking serious. It was a relatively cold day so the bird’s feathers were a little fluffed to provide more warmth; he looks very rounded.

I thought he had flown way but when I checked the videos from our birdfeeder, I found that the bird had attempted to visit the feeder….but headed to a perch was too high to get and seed. It quickly backed away and I didn’t see it again. Even though the clips from the Reolink video are a little blurry – it does show how the bird maneuvers to back away from the birdfeeder.

We don’t see bluebirds very often so this it was a pleasant surprise to see the bird. In January 2018, I managed to photograph 3 bluebirds at our birdbath!

My 2019 in Review - Photos

I managed to pick 26 pictures that were my favorites of the year either because I liked the way they turned out or because of a memory they evoked. I noticed some themes after I had collected them.

All except one are outdoors (although two were taken through my office window so I was standing indoors when I took them).

Many were pictures of plants: bare trees, witch hazel, red yucca seed pod, button bush, joe pye weed, cardoon, sunflowers, beautyberry, and red buckeye (nuts).

7 were pictures of animals or evidence of animals (other than birds): whelk shells, horseshoe crab beginning to roll over, northern red-bellied cooter (turtle), tiger swallowtail butterflies, cicada, spider, gray tree frog.

6 were pictures of birds or feathers: pelican, ibis, gallinule, bald eagle (wet), red-bellied woodpecker.

There are two sunrise pictures: one from my front porch on the first day of 2019 and one from October when we were camping in southern Virginia.

More than half the pictures are from places I go that are close to where I live (i.e. not requiring an overnight trip).

My 2019 in Review - Travel

The Space Coast of Florida….Providence, Rhode Island…Carrollton, Texas…Cape May, New Jersey…Springfield, Missouri… Smith Island, Maryland…Scottsburg, Virginia --- these were the places we traveled in 2019.

The Space Coast of Florida was for a birding festival held in January. I had quite a few blog posts about it. That road trip got the year off to a fast start for birding.

In late March/early April, I traveled to Providence, Rhode Island on the train to take the CZT class (Certified Zentangle Training). I posted about the experience of the trip and the training here.

The only plane trip of the year was in April – to Carrollton for a niece’s wedding. And it was perfect timing for the pocket prairie (posted about here).

In May, the Cape May Birding Festival…another road trip and lots of birding…blog posts.

There were multiple trips to Springfield, Missouri during the summer to help get my daughter and son-in-law moved from Pennsylvania to Missouri. It’s a 2-day road trip in each direction…often with very full carloads of fragile stuff.  And then I was back for Thanksgiving too! I did a little exploring – the botanical garden, the art museum, and the conservation nature center. The posts are here.

The first attempt at a boat trip to Smith Island in the Chesapeake Bay was cancelled due to wind in April. The re-scheduled time was in October…and we enjoyed the trip. I posted about what we saw. The pelicans were the high point for me.

2019 10 h IMG_0990.jpg

Later in October, we were camping at Staunton River State Park near Scottsburg, Virginia for a star party. We’ve been going every year that the weather permits for the past several years. It’s always cold at night but we survive - enjoy ambience of a field of telescopes, tents, campers and cars. This year we took a short hike on one of the mornings.

Looking back – our travel was full of variety (places, activities, and seasons)…a good mix. I’m already primed for more adventures away from home in 2020!

First Day of 2020

I got up early enough yesterday to see the sunrise. The clouds were too low and thick for it to be a great one…but it was the first of 2020. I did the same thing last year….with clouds making the color smudgy.

2020 01 IMG_2103 (23).jpg

We decided that the clouds were going to clear off enough to make a trek to Conowingo Dam to see the bald eagles worthwhile. It was a cold morning, so we wore snow pants and took hand warmers. As we drove in, I noticed the seagulls first; we hadn’t seen any gulls last time we went to Conowingo (in late October). As I got out of the car, I heard some eagles and saw one flying with a stick. It circled around and went up to the platform near the top of an electrical tower. I later zoomed in for a picture of the sticks accumulating for the nest. There was a nest there in previous years so the pair may just be adding new sticks…making sure the sides are high enough to contain the chicks until they are ready to fledge.

2020 01 IMG_2103 (1).jpg

The water was high from recent rains and the dam was generating power. Both gulls and eagles were benefiting from the fish available – stopped by the dam. We didn’t see any cormorants or great blue herons this time.

2020 01 IMG_2103 (3).jpg

The eagles were active but very far away on the rocks and abutment…swooping above and into the water for fish. It is very close to out of range for my camera so most of my pictures are a little blurry.

2020 01 IMG_2103 (2).jpg

There was an interaction between two birds on the abutment. They both looked rounded with their feathers fluffed and I wondered if it was from their ‘argument’ or just being cold.

Another interaction – two juveniles. One was on the rock but flew off just as the other came in for a landing.

Another juvenile was fishing…but didn’t manage to land a fish in this foray.

My husband’s camera did a bit better. He managed to photograph an adult catch a fish, jostle it into position, be chased by a juvenile…and then take the fish up to the nest. Was there a mate at the nest? We couldn’t see.

He also got some good pictures of juveniles; we are both beginning to appreciate the wing patterns of the juveniles – lots of variety in their look before they get their adult plumage.

I took a picture of one of the two cranes that are on the top of the dam facing the lake. I assume they are used to get large debris that washes down the Susquehanna from points north out of the water.

2020 01 IMG_2103 (13).jpg

Brookside Gardens – December 2019

I walked around Brookside Gardens on Christmas Eve. It was sunny, but still only in the 40s with a little breeze; I was wearing my coat and gloves…put my hood up for part of the time. I noticed a tree has been cut down recently near the junction of the boardwalk to the Nature Center with the path from the Conservatory parking lot toward the Japanese Tea House (Brookside map here). The shelf fungus growing on the stump still held the saw dust!

I noticed some birds too. The only two I managed to photograph were a White-throated Sparrow that was searching a mat covering electrical cords for the seasonal lights (the bird found at least one snack) and

2019 12 b IMG_6836 (8).jpg

A Northern Cardinal near the fragrance garden. I saw a lot of Cardinals…or maybe it was the same one following me around! Their color certainly makes them stand out.

2019 12 b IMG_6836 (10).jpg

The gardens are full of dried flowers and seeds. The sumac is the most colorful. I find the shapes of the dried ferns very appealing. They have a feathery look to them. Some of the grasses do too.

2019 12 t IMG_6836 (13).jpg

The Conservatories were my last stop – for poinsettias and the model train.

There were quite a few families enjoying the garden while I was there. The excitement and joy of the children in the model train exhibit is like experiencing a seasonal group hug!

Ten Little Celebrations – December 2019

20191225_063617.jpg

Happy Holidays!

My December had a lot of little celebrations already. I picked my top 10.

Coming home – I traveled over Thanksgiving and didn’t get home until the first of December. As usual after being away, I celebrated being home again.

Weather Conference for 6th graders – The weather was great…the students were focused…the speakers geared for the audience. It’s another annual volunteer gig that is now part of my celebration of December.

20191206_131411.jpg

Maryland Water Monitoring Conference – This was my third year to go to the MWMC and I learn something new every time. It’s a pretty intense day of learning.

20191207_132850.jpg

Howard County Conservancy Natural Holiday Sale – I love stocking the cookie table and keeping the urn full of Russian Tea. The event is always a celebration of the season.

Touch tank at Robinson Nature Center – I have a new volunteer gig! I chose something different than my other volunteering and easy to do during the winter since it is indoors. I really like the sea stars…watching the children observe the ‘feet’ through the glass and what happens when I ‘tickle’ to help the sea star let go so I can pick it up.

20191215_140302.jpg

Flying Wild and building a nest – I took a train-the-trainer type class for activities intended for grades 3-8…and one of hands on activities was building a nest. I celebrated that the one my team made managed to meet all the criteria: holding ‘marble’ eggs even when the nest moved and holding (weights) of fledglings!

Fog in the forest, birds at the feeder – It was a beautiful time looking out from the window of my office…the quiet of the forest holding the fog in the soft morning light, the birds coming to the feeder for breakfast. A moment to celebrate.

Maryland State House Christmas Trees – I enjoyed seeing all the creativity of the garden clubs…getting idea for upcoming years (maybe). It was just one of the things that put me more in the mood for all the other celebrations of the month.

2019 12 za IMG_6736.jpg

The Rise of Skywalker – It was a good ‘book end’ with the other end being the original Star Wars movie back 1977. I liked that so many story lines were resolved. Now I’m ready for a marathon watching of the other movies!

Bird feeder camera – We’re still perfecting how to mount the camera to optimize the view or our bird feeder. I’m celebrating getting the squirrel climbing the ladder as one of our early successes.

Touch Tank at Robinson Nature Center

I have started a new volunteer experience – at Robinson Nature Center’s Touch Tank. Like any new activity – the first few times are all about learning role; in this case, the biggest challenges involve opening the top of the tank (I’m not graceful at doing it…but I can do it) and knowing enough about all the organisms in it to share with people (children and accompanying adults). The sea stars are interesting even looking at them through the wall of the tank….hanging onto the glass with their suction-cup ‘feet.’

I encourage the children to watch what happens when I ‘tickle’ the sea star to loosen its hold on the glass so that I can pick it up and let the children (adults too) touch the creature. There are also milk conchs that sometimes seem like a rock at first glance. The shell is cream-colored and smooth on the side toward the sand with highlights of green and orange…and the organism is a deep red. It has eyes on stalks and, if held vertically for a few seconds, kicks!

Note in the second picture above – what looks like a top hat behind the milk conch. That is a sea urchin in hiding. They like to cover themselves with shells and other things that camouflage what they are; the hats were 3-D printed for the urchins to use for their ‘dress up.’

After two sessions volunteering at the tank, I’m well along the learning curve. One lesson learned – wash the saltwater off thoroughly (up to the elbows) when I get home and moisturize. I’m focused on my fingernails too since they seemed to be very dry and broke easily even after just one shift.

Liver cancer deaths climb by around 50% in the last decade -- ScienceDaily – Survival rates are low too. Obesity and smoking are two preventable causes.

How Climate Change Will Affect Maryland's Birds | Audubon – I looked at the page for Maryland because that is where I live. The red-headed woodpecker is on the ‘high vulnerability’ list. The data is available for other states as well (scroll down on the ‘home’ page and select by state or zip code). The red-headed woodpecker appears on the high vulnerability list for Texas and Missouri too (those are two other states I checked).

If we eat a high carb meal it will be at breakfast. I had gingerbread cake this morning!

Christmas Trees at the Maryland State House

Another holiday themed outing – driving over to Annapolis to see the trees decorated by garden clubs for each of the counties in Maryland. It’s evidently the traditional display in the central hall of the Maryland State House this time of year. We did it yesterday – a cold but sunny day…and before the wind picked up in the afternoon. I took pictures of just about every tree.

My favorite was the one done for Worcester County – lots of natural material. I particularly liked the pinecones that were cut and painted to look like flowers (they reminded me of zinnias).

I also liked the Charles’ county birds made out of felt (with the bald eagle at the very top of the tree),

Dorchester’s painted shells and pearls (the overall color of the ornaments all over the tree was a light blue),

And the dried roses on Anne Arundel County’s tree…very golden color.

2019 12 za IMG_6736.jpg

The decorations for the other trees and wreathes were very creative too.

The garden clubs all did an excellent job! I took a lot of pictures and might use some of the ideas for my decorating next year.

Gaithersburg Winter Lights Festival

2019 12 b IMG_6582.jpg

It was a cold evening last week that we drove through the Gaithersburg Winter Lights Festival. I appreciated the warmth of the car. It’s a 3.5-mile drive through Seneca Creek State Park near Gaithersburg, Maryland and the display continues from 6-9 PM each evening (except Christmas) through December 31st.

The length of the winding road provides plenty of room for light scenes on grassy areas and in the lake. We were behind a slow car which suited us just fine. I had my window rolled down at least half the time getting pictures and other people must have too; children’s excited chatter about the lights coming from the cars around us was part of the holiday cheer of the place. My husband had Christmas Carols playing out the car sound system, so we added some sound to experience as well.

2019 12 f IMG_6621.jpg

My favorite picture of the evening was a simple one….of three bright trees in the darkness.

2019 12 t IMG_6622.jpg

There was a teddy bear land area that was a lot of fun.

2019 12 e IMG_6634.jpg

And then we came to the end with a bear-in-the-box (rather than a Jack-in-the box! Time to head home in a holiday mood.

Last 2019 Student Event at Mt Pleasant

Last week the annual Howard County Conservancy ‘Weather to the Extreme’ conference was held for 6th grade students from half the middle schools in our county. I volunteered as a session moderator. As usual – I was too busy to take pictures after the students arrive…but there was a little time just after I arrived. As I got out of my car, I heard a noise in the trees just above me and the squirrel continued to work on the black walnut long enough for me to take pictures. It’s amazing that the squirrels can get through the tough shell of these nuts.

There was a tiny amount of snow overnight…still evident in a few areas…no enough to cause any traffic challenges.

The witch hazel is still blooming, and the seed pods will be forming soon. There are buds on the witch hazel that blooms in February now. I’ll try to check them every time I go to Mt Pleasant over the winter.

Very few of the cone flower seed heads look intact. The birds enjoy the seeds….and probably knock some to the ground that will grow next spring.

There are always things to see around Mt Pleasant….even on a cold and damp day!

Red Tides Under the Microscope | The Scientist Magazine® - It’s surprising what we don’t yet know about the organism responsible for red tides – Karenia Brevis. Spanish explorers of Florida in the 15th and 16th centuries described fish kills in Gulf waters. The first official documentation was in 1882 – published in the Proceedings of the US National Museum.

AP: At least 1,680 dams across the US pose potential risk – There is a link to an interactive map that shows where the 1,680 dams are located. The last paragraphs of the article are the most troubling. There are a lot of dams with unknown status. Roughly 45% of Texas dams are exempt from regulation…in Missouri safety inspections are only done on 650 of its more than 5,000 dams. And states that know about problematic private dams often can’t identify the owners to address the dam’s issues.
