In keeping with the somewhat strangeness of this season, we caught 31 birds
today, 27 of them in the first 1 1/2 hours of our 5 hour session, 25 of
them Wilson's Warblers. We joked that the Tuesday Birders brought us good
luck, since they were there for that early morning influx. Here's the
breakdown:
Northern House Wren 1
Orange-crowned Warbler 3
Wilson's Warbler 25
Lincoln's Sparrow 1
White-crowned Sparrow, Gambel's 1 (FOS, right on schedule)
I did a quick review of this year compared to last year at this time (the
only 2 years at the current temporary banding location), and we have caught
about half as many this year as last. The biggest contributor to the
decline is WIWAs (no surprise there; it is our most commonly caught species
and it would be hard for us to be this far behind if WIWAs were at normal
numbers). But other relatively commonly caught species are also behind -
House Wrens, Yellow Warblers, Common Yellowthroats, Song Sparrows.
P.S. I neglected to report on Sunday, 9/14 - We closed after about 90
minutes of intermittent drizzle and wind, after catching 2 Common
Yellowthroats.
