Teslin Lake update - October 5th



Filming Tundra Swans

From October 1st through the 5th Teslin Lake averaged 26 birds/day and 0.367 birds/net-hour for a total of 130 birds banded. It is worth remembering that at this point of the season migration watching has taken over banding as the priority monitoring method and therefore banding effort is rather recreational compared to the standard banding season earlier. Two new species for the season were banded: American Pipit on the 3rd and Hoary Redpoll on the 5th. The season 2nd Mountain Chickadee on the 1st was a pleasant surprise. The top five species banded during the period were Common Redpoll (43), American Tree Sparrow (23), Dark-eyed Junco (13), Yellow-rumped Warbler (11) and Boreal Chickadee (9). The current season top five species banded are Alder Flycatcher (637), Dark-eyed Junco (328), Yellow Warbler (309), Boreal Chickadee (231), and Yellow-rumped "Myrtle" Warbler (139).

Observation highlights included a Black-bellied Plover on the 1st, the season 1st eight Snow Geese and record late two Bank Swallows on the 2nd, and a Northern Shrike on the 5th, the first one since the very early one in August. Both the Little and the Sabine's Gull continued through the period. Migration watching was very entertaining as well as on the 1st 57 Golden Eagles were counted, locally high 191 Snow Geese were tallied on the 4th and on the 5th 500 ducks, including the season 1st Long-tailed Duck, flew by. The first peak of Tundra Swans came through on the 4th (2900) and the 5th (2100) in big impressive flocks, often very low and close so that the observers almost had to shout to each other to be heard over the cacophony of the swans!
