9-23 update

Hi Folks

Just a quick update. Friday (Sept 21) was a great migration day at Lucky Peak: the highest one-day totals for songbirds (165 banded) and raptors (522 counted) of the season. Probably this was a big movement in front of our recent rain event but this is also traditionally a peak time for abundance of migrants in this area.

10 Broad-winged Hawks were seen on Friday alone, bringing the season
total to 16. Sept 10-25 (especially the 20th-25th) are usually the
best dates for this species (with some continuing into early October) so I
expect more to pass by in the coming week as high pressure weather
resumes. Also, though far rarer (not annual), Red-shouldered Hawks
seem to appear most often in the last 10 days of September.

Songbirds are now dominated by RC Kinglets, WC Sparrows, and DE Juncos
and we are seeing an earlier than usual push for juncos (who seem to
have the most variable timing of all species we catch but often peak
in October). But, we are still seeing a some warblers, Cassin's
Vireos, Hammond's Flycatchers, & others in the mix. Pine Grosbeaks
were around for a few days late last week & I'm hoping for more ....

Happy birding,
