Teslin Lake update - August 25

Aaahhh, Foxy Sparrow!
The period of August 21st to 25th was very similar over all to the previous period. The weather was unsettled and we are still waiting for the warbler movement usually taking place around this time of the year. Banding was a bit slower with a total of 225 birds (0.389 birds/net hr) banded. The period top six was Alder Flycatcher 98, Yellow Warbler 25, Wilson’s Warbler 20, Yellow-rumped Warbler 18 and Blackpoll Warbler and Swainson’s Thrush both 10. This brought the season total to 1439 birds (0.361 birds/net hr) banded of 39 species. The current season top five is Alder Flycatcher 763, Yellow Warbler 140, Blackpoll Warbler 76, Wilson’s Warbler 67, and Yellow-rumped Warbler 63. Some of the sparrows were starting to appear more often while Northern Waterthrushes have been caught less often. Two new species for the season were caught: Fox Sparrow on the 23rd and Western Wood-Pewee 25th.

One of the most interesting developments of the last five days was an apparent start of a Red-breasted Nuthatch invasion or flight.  One or two had been noticed almost daily earlier but on the 21st 6 were seen and on the 25th a flock of three was spotted in active migration flight. At the same time we’ve had more Boreal Chickadees showing up, including 5 banded on the 24th. Maybe they’ll have another good fall movement as well. Other irregular “invasion” migrants seen included a few Common Redpolls, some small flocks of Pine Siskins and a good number of White-winged Crossbills (94 on the 25th). With the help of some north winds Greater White-fronted Geese passed over in moderate numbers on the 22nd and the 23rd (800 and 500, respectively) but only a few small flocks were seen after that and we were left waiting for the main flight. Otherwise it has been quite quiet with obs – just a few hawks heading south once in a while, the season 1st Wilson’s Snipe flushed up from the grass by the pond on the 21st and the season 2nd Parasitic Jaeger chasing the gulls on the lake on the 24th.
