A way out west here on the 99 line at Utopia the first fall
Yellow-rumped warblers
are always Audubon's, preceeding Myrtle on average by a couple weeks,
often three.
I have not had a Myrtle yet, but we have just entered their normal
arrival window.
I have had more Audubon's this fall than any prior so far (n~11).
Normally we would
have a couple per week since the last week of September, Myrtle showing
in mid-October.
Besides well over a dozen Audubon's in the last three weeks, I saw my
first-ever
large (over 20 birds) homogenous (from a Yellow-rump perspective) flock
of Audubon's
Warbler here in 11 years, last weekend. I worked them long and hard for
a Myrtle and
nary a proper chip or chinstrap was seen or heard. One Western Palm was
amongst them,
which is my first Oct. passage Palm Warbler here, and quite noteworthy
hereabouts.
Hard to believe a flock of Audubon's Warbler could be so significant,
but these are
the things micro-scale birding reveal. This is a clear and
unprecedented incursion here.
Our normal ratio in winter is 89.+% Myrtle, 10% Audubon's, and almost 1%
detectable
hybrids. Spring stays fairly near that, and once Myrtle get here in
fall that is
about normal, but until they do, it is all Audubon's, and generally
never more than
a few, most often singles on the early dates.
