Monitoring Conservation Easements

This December is my first experience volunteering to do the annual monitoring of conservation easements for the Howard County Conservancy. I went to a training back in September and then ‘shadowed’ an experienced monitor visiting 2 easements in November. In December, I was ready to monitor 2 easements with a cohort that was doing it for the first time as well.  The owners were notified by Howard County Conservancy that we would be monitoring on a particular day and the weather cooperated for both days – dry and not overly cold. The first property was mostly forest and the hike around the property was different than my usual hike since there were no well-defined trails; deer trails or picking a path through the briars (glad we were doing this in December when it was cold enough to wear heavy pants to protect my legs from thorns). It was a wonderful early winter ‘walk in the woods.’

The land was crossed by a stream that feeds into the Patuxent River. We had one stream crossing over a culvert but made another stepping on rocks; it was good that it had not rained recently. Most of the trees were native…but there was a substantial clump of bamboo growing on one streambank.

The land was easier to see with the leaves on the ground. As usual, I noticed fungi.

There was an odd holly-like plant as part of the understory. The leaves looked like holly but the top did not.

At the end of the walk, I rejoiced that the property owner had made the effort to make it a conservation easement and that it was about that same as it had been in previous years.

The second easement was entirely different: surrounded by housing developments and an active farm/golf related business rather than forest. The business was about the same as it had been in the previous year…but there was a change at the farm: a guard dog. The dog did not appear immediately, but no one was home. We could tell that there had been some earth moving going on upslope from the stream that starts on the farm and eventually flows into the Patuxent River. If a heavy rain came – a lot of soil would slump down into the stream. The dog appeared…and we decided to gracefully retreat without completing our check of the easement. The monitoring will have to be done when the owner or their representative can be there. It was a rattling experience, but we enjoyed a hefty morning snack with hot tea/latte to recover!

Maryland Water Monitoring Council 23rd Annual Conference

Last Friday, I attended Maryland Water Monitoring Council conference. The theme was “Managing Water Quality in a Changing World.” This was the 23rd conference held by the council…but the first one for me. I’d signed up as soon as I found out about it – months ago – and looked at the agenda ahead of time. The agenda was packed with interesting topics from 8:30 -4:30. Except for the two keynote talks there were 7 concurrent talks for the rest of the day plus poster presentations and vendor booths. Based on my experience with the symposium I went to back in October about the War of 1812, I hoped that I would make it through the whole day.

It turned out to be an invigorating day all the way through to the last talk! It helped that the food was fabulous and easily available, the chairs were comfortable, and the venue was large enough to provide easy transitions between sessions for the 600 attendees. Those things provided the infrastructure for the high-quality talks.

I’d printed off the agenda before the conference and highlighted the ones I thought I would be most interested in attending. Of the 12 talks I’d selected, only 1 did not live up to my expectations. At the end of the day I was very glad that I’d attended and plan to go again next year.

First Snow of the Season

We had our first snow of the season on Saturday and I got up early enough yesterday to catch some color from the sunrise.

It was the non-disruptive kind of snow: melted quickly on the streets and sidewalks but stuck to the trees and grass. On our asphalt driveway, there were clumps of snow on Sunday morning and they all were associated with a leaf!

2017 12 IMG_6940.jpg

It was very cold on Sunday morning, so I took pictures through my office window of the backyard – the sun making the forest look rosy in the background, the pines and tulip poplars holding clumps of snow, a junco comfortably sitting on the snow-covered deck railing waiting for a turn at the bird feeder.

2017 12 IMG_6952.jpg

A few minutes later – I took a few pictures through a picture from another room. The color of the morning light was fading but the pines and forest were still a pleasant scene.

2017 12 IMG_6949.jpg
2017 12 IMG_6943.jpg

I opened the garage door and leaned out to take a picture of the milkweed that are still standing in our garden. In past years the plants have lost their leaves before the frost but this year the leaves are still there, and their curls catch the snow.

Some last images of South Texas

As I finished up the post yesterday about the San Antonio Botanical Garden – I realized there were a few more miscellaneous pictures I wanted to share from our South Texas adventure. Every day near sunset hundreds, maybe thousands of birds gathered on the roofs and electrical lines around our hotel in Harlingen. The last night I managed photograph some with some sunset color behind them. Many of them are grackles.

The next morning we headed to the National Butterfly Center first but decided it was too cold and wet for butterflies to be out and about when we got there. I photographed a male and female Boat-tailed grackle on the lawn and

The water lily in the little pool.

2017 11 IMG_6402.jpg

Then I noticed a red-eared slider in the water too. It is native in southern Texas…but invasive in Maryland. It’s included in the list of the world’s most invasive species!

2017 11 IMG_6405.jpg

We headed out for a state park in lieu of the Butterfly Center and then heading toward San Antonio. The one rest stop we made along the way had this forest mosaic.

2017 11 IMG_6493.jpg

As we drove into San Antonio, I managed a picture of the Tower of the Americas through the car window. It was built for the HemisFair in 1968 and I remember making the trip to the event with my Camp Fire Girls group; I was in the 8th grade.

2017 11 IMG_6498.jpg

One last bird picture: a cold White-winged Dove taken from our hotel window.

2017 11 IMG_6503.jpg

San Antonio Botanical Garden – Part 2

Like most botanical gardens, the San Antonio Botanical Garden is segmented. The Kumamoto En Japanese Garden was probably my favorite: the water feature surrounded by plants and rocks, a mockingbird scolding us (wanting the garden to himself), a sun and moon ‘lantern,’ and stepping stones for going off the trails.

The Sensory Garden was colorful and included sculptures (like the armadillo below) that were positioned to be touched.

The Fountain Garden included ‘Christmas balls’ floating in the water and a metal flower sculpture surrounded my greenery.

We came a garden that attracted butterflies. I managed to photograph Gulf Fritillary and

2017 11 IMG_6670.jpg
2017 11 IMG_6678.jpg
2017 11 IMG_6691.jpg

I’ve always wanted to get some close-up Datura flowers and seeds…and there was a plant that was well positioned for that!

Two little surprises in the gardens: a design made with pumpkins under some trees and

2017 11 IMG_6724.jpg

A chess set in the well of the amphitheater.

2017 11 IMG_6716.jpg
2017 11 IMG_6728.jpg

There was a special display of scarecrows while we were there – created my local organizations.

The garden has several areas that talk about the various water situations in Texas: Hill country, East Texas, and South Texas.  It was more rustic than other areas of the Botanic Garden.

We didn’t see very many birds – but I did manage to photograph a hermit thrush in a tree (right off the trail in the East Texas part of the garden). I was pleased since I am rarely fast enough to get a good image of forest birds.

2017 11 IMG_6732.jpg

San Antonio Botanical Garden – Part 1

2017 11 IMG_6504.jpg

We took advantage of having a morning in San Antonio, Texas before our late afternoon flight home to walk around the San Antonio Botanical Garden. The first thing we noticed is that the garden is still being actively developed with some areas barricaded either for updating or new building. We headed to the conservatories forest. These are very different structures than the glass houses of the 1800s/early 1900s. They rise from concrete peers – high shards into the sky surrounding a courtyard. The climate in San Antonio is mild enough that even the courtyard looked lush and green at the beginning of winter!

There were sculptures in the gardens within the conservatories and the courtyard. My favorite was the ‘owl.’

The conservatories were divided by climate types: desert,

Primitive plants like cycads (l loved the color of the fresh cones)

And Screw pines (I saw the mature fruit in Hawaii and got a better look at the Phipps Conservatory, but this is the first time I saw the fruit at this stage of development).

I can’t resist the unfurling of ferns

Or the tropical flowering plants and trees.

And that was just the first part of our walk around the San Antonio Botanical Garden. There’ll be another post about the place tomorrow.

Bentsen-Rio Grande Valley State Park

The day after the Rio Grande Valley Birding Festival ended and before we headed back to San Antonio for our flight home, we visited the Bentsen Rio Grande Valley State Park. Our original plan had been to spend the morning at the National Butterfly Center in Mission, Texas but the morning was cold and wet…not conducive to butterfly activity. So we changed our plans. It was still cold and wet but some birds in the park didn’t care. This Northern Mockingbird called attention to itself with is song(s).

IMG_6410.jpg

There was an area near the nature center with paved walkways – some of them intermittently covered. We walked around the area – everything was very wet.

IMG_6418.jpg

We took the tram into the park and got off at the first stop. There was a small butterfly garden near the bird blind (where there was no action) and the rain held off for long enough for there to be a little activity. I spotted a Painted Lady,

IMG_6423.jpg

A Skipper (not sure what kind),

IMG_6426.jpg

Queens in abundance, and

We hiked a little further and came to another bird blind…and there was plenty going on there. A Golden Fronted Woodpecker enjoyed the suet.

The Plain Chachalacas were also coming in to the feeders for a snack.

Green Jays were around as well.

It started raining harder do we found a dry place to stand until the tram came bay again. There were more people on the tram for the return visit, so we got the seat on the back of tram…riding backwards. It was a good way to end our visit. I want to go back again on a day when the weather is better!

IMG_6492.jpg

The Inn at Chachalaca Bend

2017 11 IMG_6245.jpg

Our main activity for the last day of the Rio Grande Valley Birding festival was breakfast (sumptuous) as the The Inn at Chachalaca Bend followed my a walk around the grounds looking at birds. We started near the Inn’s deck on the bank of La Resaca de las Antonias. We saw a Belted Kingfisher on the electrical wires crossing the Resaca almost immediately!

2017 11 IMG_6255.jpg

A Great Blue Heron and Great Egret had a little conference in the distance.

2017 11 IMG_6258.jpg

There was a broken tree trunk (or old telephone pole) near the water….a perch for an Altamira Oriole.

2017 11 IMG_6265.jpg

Directly across from the Inn an Anhinga dropped down into the water to capture a fish then walked back up a palm that was slanting over the water.

Nearby on a snag, a Golden Fronted Woodpecker searched for breakfast.

There was a ruckus and then a larger bird flew toward us over the water and sat on the electrical wire nearest us: a Ringed Kingfisher.

There was Great Kiskadee on the wire further away

2017 11 IMG_6310.jpg

And a Black-crowned Night-Heron in the vegetation across from where were standing.

2017 11 IMG_6311.jpg

The kiskadee flew away and we notice a kite (probably white tailed…but hard to tell for sure).

We left the Resaca to hike around some open field areas. We saw an American Kestrel looking at the meadow.

As we headed back almost to the edge of the path through a forested area, we looked up and saw masses of migrating American White Pelicans! There were several groups…maybe as many as 1,000 birds.

The path branched off to the edge of the Resaca again and we saw a Snowy Egret (note the yellow feet which is a distinctive feature for this bird even if the focus is not very good for the picture).

2017 11 IMG_6371.jpg

As we got ready to leave, we gathered back at the Inn and saw a hummingbird at the feeder (probably Ruby-throated).

There were a few plants I took pictures of…but they were secondary to the birds!

Ten Little Celebrations – November 2017

More than half the ‘little celebrations’ I’ve picked to showcase in this post are from the first two weeks of the month – spent in Texas.

20171101_190825.jpg
2017 11 IMG_5055.jpg

During the first week there was a big birthday celebration for my Mother (with three kinds of cake!) and visiting Hagerman National Wildlife Refuge for the first time.

In the second week, the Rio Grande Valley Birding Festival was one long celebration that include seeing two kinds of Kingfishers on one field trip!

2017 11 IMG_6504.jpg

I still am working on a post about the San Antonio Botanical Garden – it was the first time I’d been there and a place to celebrate.

I got to eat excellent Texas barbecue in three different restaurants during the trip too.

After every long trip – I celebrate getting home again; that was true for the November travel too.

We had company for Thanksgiving this year (daughter and son-in-law) so it was a shared celebration –something to savor.

20171129_112317.jpg

And then there was the pre-staging of December activities that actually started in November: volunteering at the model train exhibit and

2017 11IMG_6795.jpg

Garden of Lights at Brookside Gardens. I celebrate the season with every child that looks with awe at the trains or giggles with delight at Nessie blowing steam.

South Padre Island and Bay Cruise – Part 3

The last part of the field trip was a cruise on the bay. The first ‘sight’ was a lighthouse with scaffolding around it as we neared the dock on our bus.

2017 11 IMG_6097.jpg

Then we were off and looking for Peregrine Falcons under the bridge. We spotted several but there was only one that was positioned for pictures.

There were mud flats with Laughing Gulls,

2017 11 IMG_6143.jpg

An Osprey surveying the scene, and

2017 11 IMG_6153.jpg

A Great Blue Heron walking awkwardly in the mud.

2017 11 IMG_6159.jpg

There was an island that provide roosting sites for Great Blue Herons (7 of them in the foreground) and Roseate Spoonbills (8-10 of them in the background).

2017 11 IMG_6168.jpg

This is the best picture I got of the Roseate Spoonbills as we cam around their side of the island.

2017 11 IMG_6181.jpg

Brown Pelicans, Double-crested Cormorants, and laughing gulls were groups on the sandy beach.

What birds to you see in these two pictures? So you see the Green-winged teals (2 males and a female), Black-Necked Stilt (2), Great Egret, Laughing gulls.

As we headed back to the dock, there were Double-Crested cormorants on pilings we were passing

2017 11 IMG_6227.jpg

And a Laughing Gull settled on the highest point of our boat.

2017 11 IMG_6234.jpg

There were so many Brown Pelicans. It’s thrilling that their numbers have recovered from the brink of extinction caused by pesticide pollution!

South Padre Island and Bay Cruise – Part 2

Our second stop was the South Padre Island Convention Center. There are boardwalks on one side of the building for birds (and other wildlife) viewing. My best pictures there were: black-necked stilt,

2017 11 IMG_5959.jpg
2017 11 IMG_5963.jpg

An alligator that was still at first but then headed toward the shore…stalking

A Common Gallinule that was making its way close to the shore (fortunately it wandered further upslope…no drama),

And a Green heron.

We walked to an area where there was a small area of planted vegetation. The small birds there were too hard to photography in the vegetation, but there were quite a few monarchs roosting…a little rest before continuing their migration.

We continued around the convention center buildings. There was a Little Blue Heron on an abutment,

2017 11 IMG_6015.jpg

A pelican almost too far out in the water (I didn’t notice the grebe until I looked at the image on the larger screen of my computer),

2017 11 IMG_6016.jpg

A Great Egret (not the black legs and feet),

2017 11 IMG_6019.jpg

And a Reddish Egret.

At the front of the convention center, I took some pictures of the facades. These must hold up to coastal storms.

There were mud flats on the other side of the convention center….mostly drying since the tide was out. There were White Pelicans,

2017 11 IMG_6029.jpg
2017 11 IMG_6030.jpg

Black Skimmers (in the foreground), and

2017 11 IMG_6046.jpg

A strutting Tricolor Heron.

2017 11 IMG_6052.jpg

As we walked back to the bus, there were some White Ibis walking across the parking lot with us. The underside of the bill was different than I expected!

Closer to the bus were some laughing gulls in the parking lot. One seemed to yawn….a good ‘last’ picture for this segment of the field trip.

South Padre Island and Bay Cruise – Part 1

2017 11 IMG_5843.jpg

Back to the posts about our experiences at the Rio Grande Valley Birding Festival…Our fourth day field trip was to South Padre Island and included a bay cruise. The first stop for our bus was at The South Padre Island Migratory Bird Sanctuary. The place is two woodlots across the street from each other and surrounded by hotels and condos on South Padre Island. There are bird feeders and baths…plantings... a ‘rest stop’ for birds. It was very quiet when we first arrived; a Cooper’s Hawk had just caught breakfast and was feasting near the back. The Monarch butterflies were still active.

Eventually the birds became active – since the hawk was busy with its prey. There was a Couch’s Kingbird eating monarch butterflies: posing on the wire for photos. One of the guides had seen the birds eating Monarch’s the previous day as well. Was it the same bird? Supposedly Monarch’s taste bad and make birds sick (chemicals they absorb from the milkweed they eat at caterpillars); something is different about the butterflies or the birds.

Orange crowned warblers shared the space in the bushes and water with the Couch’s Kingbird. These are smaller birds but share the yellow color.

There was a Great Kiskadee as well…more yellow.

2017 11 IMG_5847.jpg

One has to look hard to see the Yellow-rumped warbler.

A Ladder-backed woodpecker posed on a telephone pole.

There was a Hummingbird on an agave…too far way for an excellent image but the bill is dark so probably not a buff-bellied hummingbird. Maybe a Ruby-throated hummingbird female?

2017 11 IMG_5851.jpg

Last but not least – a butterfly. Maybe Great Southern White?

2017 11 IMG_5928.jpg

I have two more posts from this field trip…coming out tomorrow and the next day.

Zooming – November 2017

In October, most pictures were plants…this month there is a mix but 10 of the 16 are birds! It was hard to not give up and just go with all birds since there were so many in my trek through Texas. Still – I like variety. The locations of the last 6 in the series below will have detailed posts in the next week or so. Enjoy the slide show.

Laguna Atascosa National Wildlife Refuge

Our third day at the Rio Grande Valley Birding Festival did not start out well: our bus has a mechanical problem and our departure was delayed by about 3 hours. Fortunately, the replan included a lengthening of the trip by three hours and provisions (picnic lunch). On the plus side – we avoided some rain showers that moved through while we were waiting; on the negative side – we could have slept later (getting up at 4 AM is common at birding festivals!).  Our destination was the Laguna Atascosa National Wildlife Refuge. We didn’t seen any ocelots that the refuge is trying to protect…but we did see plenty of birds. The days was very cloudy and misty – not good for photographing. I picked a few that were good enjoy enough for identification.

There were snow geese coming and going. I liked this line because of the different morphs visible.

2017 11 IMG_5647.jpg

There was a Little Blue Heron fishing in the shallows

And a Great Blue Heron standing on one leg surveying the shore.

2017 11 IMG_5685.jpg

A group of Forster’s terns, with the black feathers around and back from their eyes) were grouped along the shore (looks like the birds behind them were snoozing).

2017 11 IMG_5690.jpg

The Forster’s tern is in the middle of this image. The largest bird is a Caspian Tern and the one in front is a Royal Tern. The Royal Terns I’d seen in Maryland always looked like they were wearing a black cap but that is only during the breeding season…not this time of year in South Texas.

2017 11 IMG_5725.jpg

A brown pelican flew above – following the shoreline.

2017 11 IMG_5707.jpg

White Ibis wandered through the other shore birds.

20171109_170653.jpg

The Crested Caracara were new to me. Since the ones I saw on the field trip were a little far away – I took a picture of a captive bird as the Expo.

I took a close up of a prickly pear tuna (fruit)…note the spines.

2017 11 IMG_5788.jpg

Side by side – a Lesser and Greater Yellowlegs.

2017 11 IMG_5792.jpg

We were all on the bus when a male Northern Harrier swooped down into the field beside the road and hovered over prey. I did pretty well taking this series through the bus window since there was no time to do anything better.

20171110_175150.jpg

There is a platform where aplomado falcons are nesting. This is an exciting recovery story since this bird was gone from the area for years and has only recently been reintroduced and is breeding again in south Texas. I took a picture of the captive falcon at the Expo just as I had the Crested Caracara.

We stopped at the visitor’s center and walked around the cards there. Red-winged blackbirds are all over North America!

2017 11 IMG_5831.jpg

The white winged doves are summer birds in south Texas according to allaboutbirds but there were still a lot of them around in mid-November; I wonder if they are really year round in the Rio Grande Valley.

2017 11 IMG_5838.jpg

 It was a longer day that we’d anticipated but better than we thought might happen in the hour or so after we initially learned of the bus problem. In the end we decided that the Laguna Atascosa trip was well worth it.

Santa Ana National Wildlife Refuge

The second day of the Rio Grande Valley Birding Festival, we did not have any formal field trips scheduled. It was cool and cloudy – not a good day for butterflies, so we shifted our plans back to a focus on birds and headed for the Santa Ana National Wildlife Refuge.Some of the first things we saw on our hike was insects – still with the cold: two dragonflies

Two caterpillars, and

A queen butterfly…not fluttering about.

2017 11 IMG_5455.jpg
2017 11 IMG_5383.jpg

I was pleased to see a land snail on one of the small trees. We’d seen a lot of shells on the ground (i.e. dead) at both Las Estrellas and Rancho Lomitas. We were told that sometimes roadrunners get hungry enough to crack the shells against a rock to get to the tasty morsel inside.

2017 11 IMG_5393.jpg

Ball Moss is something I had never seen. It is like Spanish Moss – also abundant on trees in the refuge.

Then we saw some duck: Northern Shovelers and Blue winged teal.

2017 11 IMG_5443.jpg

A group of chachalaca were in the trees beside the trail. It was hard to get pictures through the foliage and branches…we’d get better pictures on another day.

As we walked across an empty parking lot, we spotted a kiskadee on an electrical line

And then a flash of orange in the trees – an Altamira Oriole was on the move. It eventually made it way to the electrical pole as well.

2017 11 IMG_5479.jpg

The refuge has a swinging bridge through tree tops. On the day we were there, the birds were hunkered down but it was still work the climb and the look down into foliage.

At a bird blind, I finally got some good pictures of the green jay.

We made our way back to the visitor center and had a snack on our way to nearby Estero Llano State Park (topic of tomorrow's post). In this area of Texas there are a series of state and federal lands that make a wild life corridor…more meaningful than each standalone park or refuge.

Rancho Lomitas

After Las Estellas, the field trip group headed to Rancho Lomitas where Benito Trevino shared his knowledge of plants of the Tamaulipan thorn scrub. We learned about how cochineal became a valued commodity to the Spaniards. It is an insect that grows on prickly pear cactus (white mounds) and is used to produce carmine dye. Until the advent of synthetic dyes and pigments it was the best ‘red.’

Also the desert Christmas cholla’s berries can be used to sooth a sore throat….if one knows the process to remove the small thorns. First, use a stick to know off berries. Use the stick to separate the berries from the green part of the plant. Use a bunch of grass to move the berries around in the pebbles and dust. When the thorns appear to be gone…do it some more. I tried some. It tastes a little citrusy and would sooth the throat similarly to honey.
