A visit to Little Pond this past Tuesday evening, 9/27, (before the latest rainstorms inundated this area with floodwaters) turned up White Memorial's first-ever (in recent times) Long-billed Dowitcher. While scanning the shoreline for shorebirds I spotted a gray bird with a very long bill probing like a sewing machine in the mud. Since Short-billed and Long-billed Dowitchers look very similar, and their bills are only 1/4" difference in length, it was initially very difficult to determine which species we had. Even with the spotting scope it didn't show a definite characteristic for either species. However, since Short-billed has been seen here approximately 8 times in the past 12 years, and Long-billed had not been seen here at all in that time span, I was leaning toward calling it Short-billed or just Dowitcher sp. Most of the previous sightings have been in the spring when the two species have enough differences in plumage to distinguish them. Plus, all of the previous birds gave their distinctive Short-billed "tu-tu-tu" call notes while we watched them. Fortunately for us this time, this bird let loose with its distinctive "keek" call notes several times when it flushed and flew around for no obvious reason. The call notes clinched this bird's identification as Long-billed. These calls, coupled with the lack of striping on the head and back ruled out Wilson's Snipe, which we had just seen a few minutes before spotting this bird. Other notable birds seen on and around the pond on this visit included 52 Wood Ducks, 5 Blue-winged Teal, 13 Green-winged Teal, 4 Double-crested Cormorants, 1 Great Egret, and 2 Green Herons. Notable by virtue of high numbers were Mallards (99) and Swamp Sparrows (45). The Little Pond Trail produced our first Rusty Blackbird of the fall season, 24 White-throated Sparrows, a Marsh Wren, and a hooting Great Horned Owl as notable species. In all, this visit tallied 44 species of birds in 1 hour and 45 minutes. Three days later, after 5.5" of rain had inundated the boardwalk and the rest of the area, we only came up with 34 species along the trail leading in from White's Woods Rd. and the overlook area on the west side of the pond. With no feeding habitat available for shorebirds we didn't find any, but we were surprised to find a Sora trying to forage along the edge of the woods where the floodwaters were intruding into them. For ducks, we only saw 2 Woodies, 2 Blacks, and 25 Mallards. The rest of the birds seen on this visit were common resident and migrant landbirds along the trail, including 35 White-throated Sparrows.

What a difference a week makes! Actually, my visit to Little Pond on the evening of Thursday, 7/28, was only 5 days after our field trip out there on the evening of the 23rd. In that short time span the water levels in the pond and adjacent marsh have dropped a few inches, the Deer Fly population has decreased to a tolerable amount, and the mosquito population has decreased to a million or so. Much of the bird life is the same, with Red-winged Blackbirds, Swamp Sparrows, Cedar Waxwings, and American Goldfinches remaining abundant, but a few more species have arrived on the scene or become more numerous. My main reason for going out to this pond was to look for the Great Egrets that John Marshall and Jeff Greenwood had reported earlier in the day. They were the first ones seen this year on White Memorial property. They also become my first ones for this year when I spotted them right where John and Jeff said they saw them. Whether these birds are early fall southbound migrants from the small nesting population on Lake Champlain or post-breeding wanderers from some Atlantic coastal location we have no way of knowing. They (assuming they were the same ones) were seen again on Friday and Saturday. I couldn't find them on my next visit on Sunday afternoon, 7/31. On my visit on 7/28 I found an early fall migrant Pied-billed Grebe, 2 Green Herons, and a Solitary Sandpiper, none which were found on the 7/23 visit. My visit on the hot afternoon of Sunday, 7/31, turned up a newly-fledged Red-tailed Hawk, but nothing else that we hadn't had on the previous visits. Actually, each of these subsequent visits produced fewer species than the 7/23 visit, which yielded 51 species. On 7/28 I had 43 species and on 7/31 I had 32 species. This is mostly due to my covering much less ground than we did on the 23rd. On that day we went all the way around the entire boardwalk and trail, while my other 2 visits only took me along the north side of the boardwalk. On all 3 days we went in from the S. Lake St. entrance. It is also obvious from the number and variety of birds found that evening is a far better time to go out than afternoon. We've always known that, but these observations reinforce that belief.
