Hi All, This morning Lynda and I birded the Head of Slate Creek, the next hollow north of Compton Mt off Rt 83. We logged 30 species, but we were mostly birding by ear since most of the birds were in the tall trees with thick foliage. The highlight of the day was 3 Swainson's Warblers along the stream that flows beside the roadway. One of the Swainson's was singing a very unusual song. It was part Swainson's call mixed with a Louisiana 'Waterthrush call. The first part of the call sounded like a Swainson's with the second part sounding somewhat like a Louisiana Waterthrush without the trill at the end. I know that the Swainson's call normally sounds similar to that of a Louisiana Waterthrush, but this was different. It may have been due to the fact that its territory was at the head of a beaver pond, while a Louisiana Waterthrush held a territory just below it at the other end of the pond. I actually thought the Swainson's was a waterthrush until I got a look at it through the binoculars. We had already heard both Swainson's and waterthrush, so our ears were accustomed to both songs at the time. Other warblers found were American Redstarts, Black-and-whites, Black-throated Greens, a Blue-winged Warbler, Hooded Warblers, Northern Parulas, Ovenbirds and a Yellow-breasted Chat. At the same time we saw the Blue-winged Warbler we heard a song similar in tone to a Golden-winged song, but this song consisted of 6 notes, 3 musical notes then three buzz notes. If you were to add two more notes to the beginning of the 4 note Golden-winged song you would hear what we heard.The buzz notes were exactly like that of a Golden-winged. Maybe it was a Brewster's (Blue-winged - Golden-winged hybrid). We never saw the singer. Acadian Flycatchers seemed to be everywhere, and so did Wood Thrushes and Ovenbirds. I was glad to hear so many Wood Thrushes, as they are said to be declining in number. Once while listening to the birds, we heard a mewing sound nearby and saw a small animal scrambling through the low plants near some Rhododendron. It was about squirrel size, but didn't move like a squirrel. I could never get a good look at it, but I got a glimpse that looked as if it were a small possum, though I have never heard a possum make those sounds before. It was crying as if we had disturbed it or it was in pain. I walked parallel to it a few steps along the road to attempt a better look, and the animal flushed a Ruffed Grouse. I never saw the animal after that, but the grouse returned and started clucking. I think she probably had young ones that she was trying to round up. For those interested the complete list follows.
