Bald Eagle

I made a quick stop at the Kings Contrivance shopping center after a training session for field trips last week and spotted some soaring birds over the parking lot. The birds we most frequently see soaring over our neighborhoods are turkey or black vultures. These 2 birds caught my attention immediately because they had white heads and tails. I put my purchases on the roof of the car and tried to get a picture.

The picture isn’t great…but it was good enough to identify that the bird was a bald eagle. A woman had noticed my hurry and picture attempt and looked to see too. She came over and watched the birds for a few minutes with me….as did some others. It was a ‘bald eagle moment’ of community.

When I got home, my husband said he had been reading about a pair of eagles in our area so maybe these two have made their home in the forested corridor of the Middle Patuxent River.

I’m always thrilled to see bald eagles because they were so rare when we moved to the east coast a little over 30 years ago. There are a lot more of them now. Hurray for the birds and our successful removal of environmental toxicity that had made it hard for them to reproduce successfully.

Saturday Hike – Part II

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.

I noticed a stand of young sycamores as we started back. I wondered if they were planted or had just come up from seeds. There are not many truly large trees along the river because of the violence of the floods.

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.

We knew were past the half way point going back when we came to the Morning Choice Trail.

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

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 appreciated the leaf color of the sugar maple near the carriage house since most of the other leaves in our area seem to be staying green on the trees or falling off before they change color

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.

Cold Hike with 1st Graders

Last week, I hiked with groups of 1st graders at the Howard County Conservancy’s Mt. Pleasant Farm. It was the coldest field trip of the fall season so far – with the temperature in the 40s. On the plus side – it was a sunny day so it looked warmer that it felt.  

I arrived early to take some pictures before the buses and put on several layers before I left my car. The leaves are still mostly green.

It like the sunshine on the ferns and seed pods.

There were still a few flowers late season flowers for the pollinators still around or coming through. Apparently, there are still a few hummingbirds although they are usually mostly further south by this time.

View fullsize

There were several other field trip groups at the Mt. Pleasant on the same day: high schoolers down at the stream and a group of babies/toddlers/pre-K children with parents. All three groups arrived in about 30 minutes: the high school bus then the young group in cars that seemed to fill up half the parking lot (a larger informal group that usual) and then the 2 bus loads of 1st graders, their teachers, and their chaperones.

The students were dressed for the weather and enjoyed hiking. We talked about what lives in trees and saw squirrels and their nests….some birds. We saw the domestic chickens and goats…talked about how they stayed warm and what they ate.

The children found a snake skin on a stump…and the second group saw a very small rat snake sunning itself on an old stump.

Good hikes and activities…then hand washing and a picnic! What a great 1st grade morning!

Common Buckeye Butterfly

Last Saturday, I was at Robinson Nature Center about noon enjoying the native plant garden near the front of the nature center. When I noticed a Common Bucky Butterfly enjoying some of the fall flowers.

I took pictures from several perspectives. The colors and markings are very distinctive. It has knobs on the end of the antennae and whitish palpi between its eyes. It’s reported to like flowers with yellow centers…and that it what this individual was enjoying.

The entrance of the nature center has a nice display of fall pumpkins and squash.

I had come to the nature center earlier to participate look at macroinvertebrates in this part of the Middle Patuxent – upstream from the location for the two assessment with high schoolers earlier this week. Two differences: 1) no clams at Robinson….lots of them further down the river and 2) we found a snail…didn’t find any downstream. We found more of everything but that could have been the difference between and adult group and high schoolers….and we had more time to do the project.

In the Middle Patuxent – Day 2

Last Wednesday was the second day of the week that I volunteered through the Howard County Conservancy to help with a high school Stream Assessment in the Middle Patuxent River off the Kings Contrivance Loop trail; same location, different high school. The day still started out in near darkness…but then it was sunny!

We set up for the macroinvertebrate identification and quality assessment: collection bins and buckets and nets at the river level then tables with identification and analysis materials to the side of the trail.

View fullsize

View fullsize

I took a river level picture…much better without the rain – although the temperature was in the 50s rather than the 60s like Monday.

This time the white board worked very well to summarize the macroinvertebrates the students found and identified.

The students took pictures of the critters during the field trip. I let them borrow my clip-on macro lens. One girl had a very steady hand and took video of one showing gill movement. I took my pictures after the students headed back to school. Here are some my favorites.

Two entwined netspinning caddisfly larvae and a dragonfly larvae

A lot of dragonfly larvae…different instars and species

Another dragonfly larvae – one that seems to like this particular stretch of the Middle Patuxent. We’ll see if we find any upstream in day 3.

Several different pictures of the same damselfly larvae. We use ice cube trays to separate the critters while we are identifying them…they are ‘macro’ but not very big!

As I walked back up the hill to my car, I savored the sunny day and the near solitude of the walk.

The feeder streams still had trickles of water. One neighborhood woman that came by before the students arrived told me that the river had gotten bigger in the 30 years she has lived in the area and walked the trail. The river has dug down through sediment enough that it becomes a roaring torrent when it rains hard and rarely connects to its floodplain.

I couldn’t resist a fall leaf. Most of the forest is still green. We’re still waiting for fall color!

In the Middle Patuxent River – Day 1

Last Monday, I volunteered through the Howard County Conservancy to help with a high school Stream Assessment in the Middle Patuxent River off the Kings Contrivance Loop trail. It was raining when I left the house before sunrise and continued through the assessment.

It was starting to get lighter when I arrived at the site and helped to set up for the macroinvertebrate collection and identification.

We discovered very quickly that the white boards would not work in the rain – even if we wiped them off immediately before we tried to write.

Fortunately, the rain was gentle and water still relatively clear. This part of the river is silty…not a lot of cobbles.

We found quite a few critters. There were at least 3 different kinds of dragonfly larvae; I had never seen the kind with a more rounded abdomen. All the other critters were the more typical ones.

Paper was quickly damaged in the rain. The students took pictures and (hopefully) enough data sheets will survive to make a good composite data set for the class. I took a picture of one of the sheets. The macroinvertebrate analysis done on site showed the river to be in the moderate range.

The students finished and headed to their buses. As I made my way up the hill to my car, I stopped to look at some of the feeder rivulets along the way (there were bridges although I could have easily walked across these with my boots). There were some signs of erosion along the banks….it wasn’t as bad as I thought it might be after our recent downpours.

Composting at Home – October 2018

After 3+ months of use my compost bin no longer looks pristine.

I have started piling small sticks around it to cut down on the rain drop splatter from the bare soil under the red maple. The maple roots are very dense and close to the surface…the shade very deep…nothing grows very well there and the soil is eroding down to the maple roots. It has been a good place to put the bin and I’ll leave some of the compost in place with sticks to hold it ---- and hopefully encourage more vegetation to grow. The brush pile is having that effect further down the slope.

We are just beginning to have leaves on the ground – oak and sycamore mostly.

I’ve been using the leaf blower in reverse with a bag attached to catch the lightly shredded leaves. The process works best when the leaves are dry (a challenge recently with all the rain we’ve been getting) and on hard services like the driveway, street gutters, and deck. I’ve discovered that a little shredding goes a long way speeding decomposition.

I typically add the veggie scraps from the kitchen on top then turn some leaves over it. Recently I’ve had more because fall veggies tend to have seeds and skins compost. I’ve also admitted to myself that I don’t eat nearly as many potatoes as I used to.

Even though we’ve been getting rain, the compost probably needs to be watered to ‘cook’ as quickly as possible. The shredded leaves can absorb a lot of moisture, so my plan is to add water with every bag of leaves. The hose barely reaches from the faucet to the compost’s bin location. I’ll have to think about where else I might put it that would be easier to reach and not too close to the house.

Ferns under the Deck

Our deck is over a story off the ground and it always in deep shade. I planted some Christmas fern a few years ago and it is almost overwhelmed with the splash from between the decking above. I think this is the first place I will put compost (as mulch) when it is ‘done’.

I thought he shade would be ideal for the fern and that it would propagate itself. But the muddy mess is not good for anything growing there unless I can find a way to improve the situation. Having mulch instead of mud should be an improvement.

On the other end of the space under the deck there is some moss growing and maybe some little ferns. I’m not sure. I’ll spread some around them when I disperse my compost. The deer don’t seem to be bothering them so far.

A Few Minutes Observing…a female cardinal

Taking pictures through my office window with my new camera is a bit more challenging than it was with the old camera; getting the lens camp off takes too much time. But there was a female cardinal that stayed perched on the gutter long enough for me to get a portrait.

It was a cool breezy day and the bird’s feathers are fluffed…the crest is a little rumpled too (a bad crest day?).

I noticed some leaves in the gutter; it’s not clogged yet but it could get that way with more leaves flying in the next few weeks.

Right now – most of the leaves visible from my window are still green…with a few patches of color. The tulip poplar leaves go to yellow and

The maple will go to red. Eventually.

And that was my few minutes observing through the window!

Spider Webs at Centennial Lake

Spider webs stand out when they have water droplets on the silk – either from dew or fog (or water sprayed by a photographer keen to photograph them). Last week at Centennial Park the water droplets were from fog. I was surprised at how many spider webs I saw along the path…. realizing that there are a lot more spiders around than we usually notice.

Some of the webs had probably caught something since they had gaping holes.

Others were more intact or maybe partially repaired.

As I was getting ready to leave the park I notice a large funnel web near the trunk of a pine. It too was more visible because of the fog. I didn’t see the spider, but it was probably there somewhere. I was so focused on the webs in the trees that I wasn’t looking for the funnels on the ground!

Mushrooms at Centennial Park

On the foggy morning I spent at Centennial Park last week, I found some tiny mushrooms in the raised bed across the pathway from the boat rentals. They were growing in the mulch and were ‘fruiting’ because of the very wet conditions we’ve had recently. Some were very hard to spot because their color’s were not that different form the mulch – and they were small. I stood far enough back so that I could use the zoom to photograph them without climbing into the mulch.

There were some birds nest fungi that were mostly empty nests although a  few of the ‘eggs’ were still nearby.

My favorites were brightly colored like these very small red mushrooms (note there is a centipede just to the left of the mushrooms).

My favorites were some tiny orange mushrooms with yellow stalks and edges. They seemed to be glowing – standing out in their drab surroundings.

I walked over to some pine trees near the parking lot while I waited for my husband to finish his brisk walk around the lake. There were some larger mushrooms coming up through the pine needles.

CSA Share

The Gorman Farms CSA season is about done but I am enjoying everything in the shares we are getting. A recent share filled the ceramic top of my stove. There are carrots with more top that carrot – but I like the tops in salads and soups; as soon as I got them home I cut the tops off, cleaned them and put them in a plastic bin with the parsley. I’ll eat the carrot tops first since they won’t last as long as the parsley. The carrots themselves will be eaten with hummus for snacks. They were very muddy. Heavy rain and mud has made harvesting more challenging than usual in our area.

I haven’t tried the watermelon radishes yet but I have enjoyed them in seasons past. We’re still getting a couple of onions every week which fits well with the way I cook. I’m a little behind on the winter squash; at some point I’ll cook them all and freeze the pulp to use like pumpkin. There were three tiny versions of butternut squash in this share; supposedly they are even sweeter and cook faster because they are small. The purple cabbages are small – struggling in the soggy fields probably. The peppers are holding strong; there were bell, banana, and roasting peppers in the share. And then there are sweet potatoes…several pounds every week; I’m saving the ones that are cured to eat after the CSA is over for the year. There was quite a selection at the overage table and I picked the fennel; I’ve developed a taste of it…since joining the CSA several years ago; I’d never tried it before that.

Good eating in October!

Foggy Morning at Centennial Park

Earlier this week, I enjoyed doing some photography at Centennial Park on a foggy morning. The lake was a little high from the recent rains and the fog muted the colors of the trees (still mostly green).

I stopped at a dogwood tree to capture the buds for next season and the seeds from this year.

View fullsize

View fullsize

There were some colorful leaves that showed up better at close range.

There were some fall flowers at the edge of the lake – somewhat protected from the water run off by a large rock.

There were not very many birds around:  a few Canadian geese on the lake

And a mockingbird. Note the small spider web in the picture with the mockingbird.

The spider webs and small mushroom growing on rotting mulch were the photographic high points of the walk. I post more about them next week.

Shelf Fungus

There were several tree trunks/branches thick with shelf fungus that I photographed last Friday during my muddy hike in the Middle Patuxent Environmental Area). The first was a tree standing by the river – exposed roots holding it right on the edge. There were at least three different kinds of fungus on the trunk.

Perhaps seeing that tree made me more observant as we hiked further along the along the loom of the South Wind Trail. I spotted some bright orange fungus on some fallen branches beside the path. The color jumped out – a contrast with the greens and browns on the forest floor.

With all the rain we’ve been getting – there are quite a few fungi around…and they are fresh enough to be brightly colored. They are fun to find and photograph. Exact identification is frustrating for most of them, so I am lumping these as ‘shelf fungus’!

Rain and the Middle Patuxent

Last Friday, I had all my gear prepped and was almost walking out the door when I got the word that the field trip for high schoolers to assess stream health in the upper part of the Middle Patuxent River (in the Middle Patuxent Environmental Area) was cancelled. There was a line of heavy thunderstorms come through the night before and crossing the river on rocks was impossible. It’s been a rough fall for stream surveys with all the heavy rain we’ve gotten. I waited until mid-morning then headed out to see the high water myself – recruiting my husband to go along. It is about 15 minutes from our house.

Like a lot of forested areas in our county, there are scheduled deer management hunts posted on bright red signs. There is a similar one in our neighborhood for the forest behind many of our houses (and down to the Middle Patuxent River).

The South Wind Trail started out as older asphalt then became grass with some muddy places.

I saw some Christmas ferns under a low growing tree just off the path.

The closer we got to the river the muddier the trail got. The ground was clearly saturated. It would have become quite a quagmire with 60+ students, teachers, and volunteers hiking down to the river.

At the river the water was higher than I’d see it and foam was floating on the surface. The rocks we used to get across the river where we did most of the sampling were partially submerged…to dangerous to cross the river. The amount of sediment and rapid flow of the water would have made it had to find macroinvertebrates as well.

At first, I thought the gray areas of the rocks close to the river were lichen, but when I looked more closely, the areas looked more like they had been scoured and the lichen might be starting to grow again – very slowly.

As we continued around the loop to get back to our car, a part of the trail looked like it was becoming a rivulet into the river. Since the water had not made a ditch yet, it might be something that has just happened this fall.
