Saw Mill River Audubon went on a trip to upstate New York this past weekend. We visited the Cornell Lab of Ornithology in Ithaca for a few hours and spent the remainder of the time at Montezuma Wildlife Refuge. I had been to Montezuma before – twice – but never to the Lab.

The Lab was established in 1915 by ornithologist Arthur Allen. Students, scientists, educators, researchers, and citizens scientists collaborate to fulfill the Lab’s mission: “To interpret and conserve the earth’s biological diversity through research, education, and citizen science focused on birds.” Perhaps you have heard about their webcams, or their informational websites All About Birds and Birds of North America. They are most known for their ornithology program, but also offer majors in, for example, evolutionary biology, ichthyology, and animal science.

The Lab is located in Sapsucker Woods Sanctuary. Early in the 20th century, Allen and artist Louis Agassiz Fuertes wanted to save the woods from logging. They purchased 150 acres after receiving a wealthy student’s donation. Allen and Fuertes chose to name the land after the Yellow-bellied Sapsucker; it was the first place in the Cayuga Lake region where sapsuckers were spotted breeding. Over time, more and more acres have been added, totaling more than 220 today.

After we arrived and checked in, we lunched by the lake. Canada Geese, Mallards, and American Black Ducks foraged for food on the gravel shore by the building. I never had such close views of black ducks. They are the second-most common ducks I see, behind mallards. In the distance, black ducks usually look like plain dark blobs. Here, I could make out the finer details of their plumage. Certain ducks such as this may not look as grandly vivid as the Wood Duck or Green-winged Teal, but they win a place in the subtle beauty contest.

The only exceptional ducks were the two female Hooded Mergansers. They were shy and very aware of us. Once we reached our lunching spot, they swam to the far side of the lake and hid themselves.

We had some time to kill before our tour and walked on a trail. By this time, day passed noon. The weather was sunny but unusually warm for this time of year – the temperature climbed past sixty degrees. We had to shed multiple layers. I wasn’t surprised by the lack of activity during our walk.We saw and heard a few typical winter birds: goldfinches, titmice, chickadees, a couple downy woodpeckers, blue jays, white-throated sparrows and a white-breasted nuthatch. There wasn’t much else to see on the lake.

A Lab student studying ichthyology led our behind-the-scenes tour initially. She first showed us and talked about the large mural in the lobby and Fuertes’ paintings. We then ventured behind a closed door to a hallway of classrooms. After we spent some time in a classroom, Charles Dardia – the Collections Manager of the Museum of Vertebrates – suddenly appeared and took over as our guide. He led us into another classroom where students work on stuffing birds and preserving wings. One student was just beginning to disembowel a young robin, carefully starting to make a small incision in the skin.

My birdwatching hobby kicked off while I studied for graduate school. Ever since, I kept thinking how the birding bug bit me too late, that I could have gone to school for ornithology instead of writing, and that I think I would be capable of handling stuffed birds.

Then I went on this tour. As I watched the student progress with her incision, I saw the skin’s pink underside and started feeling nauseated. First off, I was dressed far too warmly and only brought wool socks with me. I tend to feel sick in the stomach even after removing layers. Then the sawdust and mothball aromas started to get to me. I managed to stick around long enough to see another student bring out a pair of Turkey Wings he had worked on, but I had to leave the classroom eventually.

Thankfully, the next room we went in was refrigerated. The Lab keeps its 190,000 jars of preserved fish here. The Lab preserves the fish and loans them to scientists and other schools. One can study DNA and the evolution of tooth development, for instance.

Then we went to a large room – the most exciting part of the tour for any birdwatcher. Yes, this is where they have the drawers and drawers and drawers of stuffed birds from around the world, sorted by taxonomy. I braced myself for the beautiful dead.

Mr. Dardia opened the drawer of Wandering Albatrosses and the most hideous odor I had ever smelled waffed out.

I gagged. Instant nausea. I stayed in the back of the group and kept a hand over my mouth and nose almost the entire time. Unfortunately, I missed what Mr. Dardia talked about. My mind was completely occupied by the odor and struggled to take pictures.

We got the best chance we would ever have to see these three extinct species:

 

Though I was relieved to finally exit the room, I was convinced the odor stuck to my clothes. Next, we took a look at Ralph the reticulated python, whose skeleton was mounted on the hallway wall. The skeleton’s length reached 19 feet, but, alive, Ralph was 26 feet long. Ralph could have eaten children.

Mr. Dardia had to take off, so the Lab student resumed her position as guide. She talked a bit about the Elephant Listening Project, in which acoustic biologists study the infrasounds of elephant communication. The scientists know each elephant so well that they could tell whose footsteps are whose.

Our tour ended shortly. After a break, we headed north to Auburn.

Brinton Brook Hike, Report 11-2016

This morning was chilly (the temperature was in the 30s) but sunny and clear. Most trees had lost their leaves, with the few recognizable exceptions: American Beech, Norway Maple, White Oak, Tulip. The forest floor and parts of the trails were covered with brown leaves from oaks, maples, sycamore, sassafras, and other trees. The group this month consisted mostly of Saw Mill River Audubon affiliates, plus a member from the Weinstein family.

The first half of the hike was so quiet that it was more like a nature walk than a birding walk for us birders. We didn’t observe many species. The regular members of the winter flock included a few chickadees, titmice, and nuthatches; unseen White-throated Sparrows; and a couple Red-bellied and Downy Woodpeckers. Blue Jays cried here and there. We heard a Golden-crowned Kinglet flitting around mid-story but didn’t get a chance to see it. At the pond we counted ten Mallards. For a certain time, we made more noise than the birds, crunching leaves as we walked.

During our ascent to the power lines, a Turkey Vulture and then the lesser common Black Vulture soared behind the trees. Mike – hike leader – found a few Barred Owl feathers on the trail. They felt very soft. Since Barred Owls don’t usually leave their feathers around like this, we guessed a Great Horned Owl must have tackled it and carried it off somewhere to eat.

Rudy – the sanctuary caretaker – checked one of the nest boxes and found a square-shaped bluebird’s nest.

At the power lines were more white-throated sparrows, a couple cardinals, an acrobatic mockingbird, a Carolina Wren, a couple more TVs, and a far away screeching Red-tail Hawk. I expected American Tree Sparrows. They would have been first-of-season for me. It was about they’d begin to show up in Westchester. A few were already sighted at the Croton Point landfill a few days before. I didn’t observe any here. I did see this dead Box Turtle, which had been in the same spot since Sunday, according to Mike (we moved it off the trail.)

We reached the section of the power lines trail that goes back into the sanctuary. Pishing happened, disturbing a chickadee feeding on wild lettuce. And then out came a Fox Sparrow! It perched on top of a bare bush for up to a minute. Very agreeable of it. This sighting was my second for the season, but I welcomed the sight of a Fox Sparrow to enliven the birding. I don’t often see them.

The rest of the hike had much more activity. I observed more of the same birds from before, but more numbers of each species flitted around and foraged for food. The Dark-eyed Juncos especially revealed themselves more, venturing onto the path. We saw at least a half dozen Cedar Waxwings and a second Fox Sparrow. A Common Raven flew overheard and croaked. A Northern Flicker “pew”-ed. A couple more Carolina Wrens trilled.

Overall, I observed 23 species of birds: http://ebird.org/ebird/view/checklist/S32502820.

Mother Said to Play With My Food

Last October, when I went to retrieve something from the dining room, I caught a fluttering movement outside. Just a few feet from the windows stood an immature Cooper’s Hawk on the ground, facing the windows, beneath the row of towering white pines. In spite of the thick coating of dried needles, I could see it clutched a chipmunk in its talons.

I called to my parents in the loudest whispering I could manage. They had never see a Cooper’s Hawk before. I pointed out how I knew it was an immature: yellow eyes and dark streaks on a white breast.

We thought the Cooper’s would begin to rip apart the chipmunk. But wings drawn and pantaloons in full view, the accipiter hopped. And hopped. And hopped. The chipmunk was flung upward with each hop, grabbed by talons before it could touch the ground, and then released into the air again like a hacky sack. The chipmunk looked very dead. Its eyes were closed and its mouth was agape.

I couldn’t believe I was able to get such a close look at a raptor I didn’t see much. My last exceptional encounter was more than a year before. I observed a young Cooper’s play catch-that-prey with a live squirrel at a park. The squirrel somehow comprehended that the hawk was practicing without an intent to kill, so it went about its nut collection business apathetically, even when talons came pretty close to poking through its skin.

We watched the Cooper’s repeatedly hurl the chipmunk into the air. My mother was  as astounded as I was at how the hawk was so close to us, but she also grimaced and cried out “Awww” and “Poor thing!”. I responded I didn’t understand why she felt sympathy for the chipmunk. It was already dead. And it wasn’t like it was being ripped apart to reveal bloody muscle and innards. One doesn’t usually get a chance to see something like this – a raptor practicing its killing methods on a dummy.

As we talked, the chipmunk suddenly raced away as soon as it came close to touching the ground. The pine needles rustled as it scuttled underneath the bed. The moment the chipmunk escaped, the Cooper’s looked straight ahead for a split second – as if it were a character from “The Office” gaping at the camera – and then it clumsily scrambled after the chipmunk.

They had gone over the hill’s ledge just beyond the pine trees. We could make out that the Cooper’s easily succeeded in recapturing the chipmunk, but after that, the Cooper’s moved a bit further down the hill, and they were completely out of our sight. We left the room.
