Teslin Lake update - August 20


Always a crowd pleaser - an adult male American Redstart (also known as Halloween bird)

During the period of August 16th to 20th, the weather was somewhat unsettled but mostly nice. The morning of the 19th with start temperature of +2 was the coolest one of the fall so far.  The Alder Flycatcher movement slowed down and as there was no real push from warblers yet the daily banding totals went down significantly. A total of 284 birds (0.437 birds/net hr) were banded. The period top five was Alder Flycatcher 152, Yellow Warbler 30, Wilson’s Warbler 20, Yellow-rumped Warbler 19 and Blackpoll Warbler 17. This brought the season total to 1214 birds (0.357 birds/net hr) banded of 37 species. The current season top five is Alder Flycatcher 665, Yellow Warbler 115, Blackpoll Warbler 66, Dark-eyed Junco 52 and Wilson’s Warbler 47. The only new species for the season was Townsend’s Warbler on the 17th. Other banding highlights included two Least and one Dusky Flycatcher among all the Alders and yet another Belted Kingfisher.

The period was rather quiet outside the nets and real highlights were hard to come by. There was increasing bird activity on the lake and some of the higher counts included 26 Common Loons on the 18th and possibly a station record 103 Red-necked Grebes on the 20th, 52 fly-by Surf Scoters and 20 adult Thayer’s Gulls on the 19th. An adult Glaucous Gull was another somewhat unexpected arctic bird far south this early on the 18th. On the 20th the season first American Pipits and Say’s Phoebe were seen as well as the season 2nd Peregrine Falcon.
