My husband Barry got back about an hour ago from seeing the Pacific Loon in the Washington Channel, from about 2 pm to nearly 3 pm. When he first arrived, he started scanning from the first parking lot after Ohio Dr. becomes one-way, without seeing the bird. After several stops he started to get worried. However, he eventually located the Loon close to the Hains Point seawall about opposite the point at Ft. McNair (where the Anacostia comes in). When he walked up to be level with it, it showed signs of agitation and swam/dived away from him to be about 20 yards out. He then stood very still and it came back, and resumed feeding right along the seawall, always moving upstream (towards the bridges). For a while it sat and preened, then dove, caught, killed and ate an eel, only about 3 yards away! It then commenced diving regularly, obviously into a "feeding mode." He followed it to a point about half-way back to the beginning of the one-way stretch. He noted several points re the ID (and is writing notes). The throat patch was definitely purple glossed. The white neck stripes were thinner than the black, a point for Pacific as opposed to Arctic Loon. The nape was "puffy" and paler grey than the face, again supportive of Pacific Loon. There was no white flank patch, although it sometimes showed a bit of white at the water line. Appeared to be about 6 neck stripes (he isn't 100% sure on this) which could be either species (this characteristic overlaps). Barry has seen Black-throated Diver numerous times in the UK and Pacific on the west coast, and the two together in 1991 in California. A very nice bird -- wonder how long it plans to stay?
