Dave,
As if you willed it, a Palm Warbler was reported from a private residence
in Boulder County this morning.

Two additions (hooded and bay-breasted) bring the total species of warblers in
CO since November 1, 2022 to 23. That is pretty remarkable. "Misses" (with a
small "m") from the 2022 list would seem to be palm and blackburnian, as they
have occurred more than once late in previous years.

Great questions! Christiaan Both (Groningen University) has been examining
some of them. See, for example:

Thank you as always, Dave Leatherman! I (and so many) always love your
observations, photos, explanations & information, and especially (as here)
your musings & speculations (based as they are on science and an
experienced, open & inquiring mind)!! Always sharp & insightful.

Kudos to Lori Z. in Fort Collins for finding a very late Northern Waterthrush
along the Poudre which was warbler species #19 on my draft list for CO since
November 1, 2022. Brandon and Tyler have added Cape May and American Redstart,
respectively, for a total so far of 21. People fluent in
By my count, Colorado has hosted at least 19 species of warblers since November
1st. I probably missed one or two. The list jotted down includes (in no
particular order):
prothonotary
black-and-white
northern parula
yellow-rumped
chestnut-sided
yellow-throated
pine
Nashville
Townsend's
