The Stroud Preserve, 1 February 2013

Today the Stroud Preserve was best described as pretty much an avian desert. It was cold, windy and quite. Very little was moving about at all. My walk today functioned more as a cardio exercise for me than a bird walk. However, there were a couple of patches of sparrow feeding guilds at kept the walk from being a total bird bust. These are usually dominated by White-throated Sparrows and will have other birds mixed in, including tree birds like , bluebirds, nuthatches, chickadees, and woodpeckers. One of these mixed flocks had about 80% of all the individual birds I saw today. It also had a “herd” of cardinals, 38 to be exact. They were all feeding on the open ground with other sparrows and juncos. It was about evenly split between males and females. In my experience, I rare see that many cardinals in one group.

I had company on my walk today. I met Kelly Nunn in the parking lot. She was visiting from the Kennett Square area. Now that I think about it, this was the first time that anyone has joined me for a full stroll around the place. I had also planned to met another other birder, Larry Lewis, this morning as well. But I didn’t see his group around at the parking lot, so Kelly and I took off instead.

While it was nice to have an increase in birders around the preserve, it would have been nice if more birds showed up. With the unseasonably warm weather that we had today I had high hopes for lots of bird activity. Even though the final species count was on the high end for this time of year, the total number of birds was fairly low.

Still of interest for me is the influx of Fish Crows. Today we counted at least ten in the scattered flock of American Crows. This is strange as I went most of the year prior to this with on a few Fish Crows at all. The Great Horned Owl was still tending to her nest. I am tempted to bring my spotting scope with me on the next visit so I can get a close up and personal look at it.

I did get an email from Larry later in the day. He said that they got to the preserve a little late but did have a nice walk. Their highlight was a Brown Thrasher. They also saw two Wilson’s Snipe and 5 Swamp Sparrows, which we did not see.

Other birds of interest were 2 Mute Swans, 8 Ring-necked Ducks, and 2 Black Ducks in a farm pond on a property adjacent to the preserve along Strasburg Road. The Swans have been there for about a week but the other ducks showed up today.

What a difference a few days makes. Today it was 43° Less than a week ago it was 12°. The birdlife was more lively as Carolina Wrens, Blue Jays and the likes were more vocal. Bluebirds were back in force. Actually, I don’t think that they ever left. I imagine if I were to check the Bluebird Boxes or other cavities around the preserve during the cold snap I imagine I would have found masses of them huddled up in a blue bunch of fluffy feathers. I do remember seeing a female Bluebird going in and out of a natural cavity in a tree a few weeks ago and wondered it that was an overnight roost for them.

I had a number of highlights on my walk today (in bold on the species list), but for me the best was having a Fish Crow and American Crow sitting near each other in profile where I could (finally) get a good look at the two. I have heard many Fish Crow calls from the preserve but being away from the area for nearly 20 years and knowing how variable crow calls can be I’ve been wondering if I am getting these calls correct. Also, I never hear of any other birders from the area mention that they see Fish Crows.

I heard what I would call a classic Fish Crow call from a small mass of crows in a tree near the Brandywine. I carefully watched until I found the crow that was making the Fish Crow call. I found it sitting just underneath a calling American Crow. The size difference was easy with the Fish Crow noticeably smaller and slimmer than the American Crow.

I’ve always been fond of Fish Crows as it was one of the few nesting birds in my old neighborhood at 5^th and Cecil B. Moore in North Philly. We were some distance away form the Delaware River but they certainly liked the urban wasteland there. The only other native nesting bird that I can recall from there was American Kestrel. The photo on the left is a rotten shot using my phone. Both crows were in profile and facing the same direction. You can (maybe) make out that the bottom one is smaller. If not, you will have to take my word for it! I think the first thing I will do when I get gainful employment again is get a decent camera for things like this. Nonetheless, it will have to do for now.

The Stroud Preserve, 27 January 2013

I had a pretty late start today and things seemed slow that I thought perhaps I didn’t need to bother with any field notes for the blog, however, there were a couple of interesting things to talk about. Also, as you can see from the photo above, it's just nice to see the place in a different light some times. 

To start with, a couple of birders that I ran into as my walk began flushed up a Wilson’s Snipe, which is always a good bird to see around here. I then showed them where the Great Horned Owls nest was. The female was faithfully sitting on the nest.

Other than that most of the walk was as quite as I have ever seen it here. As I approached the Brandywine I saw a flock of 24 Common Mergansers flying south down stream. As I scanned for more birds on the wing, I noticed a flock of about 50 birds high overhead. Looked and they all appeared to be gulls. As on 18 January, when I observed other large groups of gulls streaming past, these were made up of mostly small gulls and a few larger ones. My assumption is that these are Ring-billed and Herring Gull. Today howerver, they were flying the exact opposite direction as they were a week ago and there seemed be fare fewer Herring Gulls mixed in. They kept streaming past in groups of 20 to 75 birds for the next 20 minutes or so. In all I estimate approximately 1500 gulls passed over with only about 12 or so Herring Gulls.

After it seemed that most of the gulls had flown past, I got into my car and head out of the parking lot. As I pulled up to Creek Road I saw a large raptor flying directly towards me only a few feet above the ground then right as it got the to road, it pulled up and landed on the telephone pole right in front of me! I saw a thing hanging from its feet that looked like the tail of some rodent. At last! A Peregrine Falcon!

Or not. It was without doubt a large falcon, but it was very pale, not anything like the Peregrines around here should look. I thought “is it a Gyr?” But it didn’t look right for that either. The sideburns were to distinct and it had far to slender of a build. Then I thought, perhaps the rodent tail wasn’t a tail after all but jesses instead. I looked. And indeed it was a jess. The photo on the right is poor, but you can make out the jess in it.

I looked at if for another minute or so and then it flew off across the field right to where the falconer was swinging a lure around in large circles on a tether. That was a bit of a relief because it makes my issues with identifying it a little less embarrassing. I think it was some pale race of a Peregrine or a Lanner, or some combination therein. I’ll have to wait a bit longer to get a wild Peregrine (or a Lanner) for my preserve list!

Today’s walk, like every other walk this week was cold. However, the wind was not blowing at all, so it was a pretty enjoyable walk. My first impression starting out was that it was going to be a really slow day because the landscape as such a dead silence to it. Nonetheless, it wasn’t that bad. The birds mostly occurred in bunches. I would walk for 5 or 10 minutes and not see very much at all, then all of the sudden the ground would be crawling with sparrows. Most of which were White-throated. The old pond bed was pretty active with sparrows as well.

Last spring I found a pair of Red-tailed Hawks with a nest in a large tree on the north side of the preserve near the high tension power lines. I thought  to myself when I saw “that will probably be were I’ll get a Great Horned Owl. All winter when I walk past it I have checked to see if I could see a Great Horned peeking over the side. Today when I looked up I did indeed see a pair of eyes looking back at me! My guess is that this is a female on eggs. I is kind of hard to think about incubating eggs in these temperatures!

Also was interest today were 6 American Pipits that worked their way through the grass nearly at my feet. Actually, they were about 8 feet away as they were at the edge of the near focus of my binoculars. The foraged as if I were not there.

Today’s walk was cold. I’ve been trying to figure out if it was the coldest day or not and I think I have developed a test to determine this. Let’s try it out now.

On 22 January 2013 was the East Branch of the Brandywine frozen? No.

On 23 January 2013 was the East Branch of the Brandywine frozen? Yes.

There you have it. Today was more colder* than yesterday. However, I must be honest in that it didn’t feel more colder because the wind wasn’t howling like it was yesterday. Again I employed my graduate school education and checked the weather before I left the house and was dressed appropriately. It will be interesting to see if the Brandywine completely freezes over as the temps are supposed to stay subfreezing for the next four days.

Despite the low temperature, the lowest that I have experienced since moving back the east coast, the birdlife today seemed a little more robust than yesterday. I started off the day with an adult Bald Eagle, which was a first for 2013. The last one that I saw was back on 11 December. They were an almost daily occurrence through to November then they began to disappear.

Speaking of disappearing acts. I was watching the group of about 500 Canada Geese in the field on the west side of the Brandywine when I looked up at the eagle. I looked it for a minute or so then looked back at the geese. Except there were not geese! They had all slipped in the Brandywine without making a sound! Penn and Teller couldn’t have done it better. In all I had 33 species for the day and I'm up to 59 for the year. 

*More colder is a precise technical term used by field ornithologist to describe their level of discomfort at any given time.

Don’t let the photo of the sunny sky fool you. Today was a flippin cold! If I said it was cold on any other day this winter I was wrong.  I started out the day at 18 degrees and by the time I got back to the car it had climbed all the way up to 19. Oh, and the wind did blow! Fortunately I used my grad school education to check the weather and dressed appropriately...before I left home. So, I was pretty warm with the exception of my nose. The birds didn’t like it much either. It was pretty darn quite. Some regulars like Morning Dove, Eastern Bluebird, and American Goldfinch were completely absent.

What drives a person to go out on a day like this? Well, I have been reading about all the wonderful winter finches that other birders in the region have been seeing. White-winged and Red Crossbills, Northern Shrikes, Common Redpolls, Evening Grosbeaks are abound everywhere but here. Other than hundreds of Purple Finches and a single day of Pine Siskins, I have not had any of these wonderful visitors from the North. They certainly were not around today. In fact, had the lowest total species tally thus far in 2013 with a whopping 28.
