| A Golden-crowned Kinglet - mi vida!! |
The period from September 16th to 20th
had the feeling of approaching winter, not so much because how the weather was
but rather because the variety of bird species was getting noticeably smaller
and the majority of birds caught were typical end-of-the-season birds. Each day
we banded fewer birds than the day before and so we ended up with 166 birds
(0.284 birds/net hr) for the period and for a current season total of 2229
birds (0.341 birds/net hr) of 46 species. The period top five was Ruby-crowned Kinglet 41, Yellow-rumped Warbler 37, Boreal Chickadee 21, Dark-eyed Junco 14 and Orange-crowned Warbler 11. The current
season top five is Alder Flycatcher
827, Yellow Warbler 224, Yellow-rumped Warbler 190, Ruby-crowned Kinglet 116, and Wilson’s Warbler 114. Three Golden-crowned Kinglets were banded on
the 17th for a 1st record for the season. Other birds of
interest included 2 Sharp-shinned Hawks,
the season 2nd Varied Thrush
on the 19th, and two late-feeling birds – an American Redstart on the 16th and a Blackpoll Warbler on the 18th.

The period was fairly slow with observations too. On the
16th there was a little bit of waterfowl movement, something we
don’t get much for whatever reason. The highlights included 180 Surf Scoters, 20 White-winged Scoters and 124 Common
Mergansers. The same day was a bit of a gull day as on top of our regular
suspects we also spotted an immature Glaucous
Gull, a juvenile California Gull,
and two Herring x Glaucous-winged Gull
hybrids. Obviously California Gull is the rarest of these as the species is
barely annual in the territory. The others we see on a regular basis but in
small numbers late in the season. The next these were all still present and
joined by a juvenile Herring x Glaucous
Gull hybrid. Also on the 17th, the season 1st Northern Shrike, just over 300 Yellow-rumped Warblers and 200 Pine Siskins were seen passing by our
observation site. The highlights for the 18th included another
almost 200 Pine Siskins, 66 Bohemian Waxwings, 3 Three-toed Woodpeckers, about 70
raptors, and the season 1st two Mountain
Chickadees. The only highlight for the 19th was the season 1st
Long-tailed Duck and absolutely
nothing happened on the 20th – it was almost as if all the birds had
disappeared from the surface of the planet!
