There has been a lot of migration this past week! The rain last week didn't
slow the birds down for long, and the strong southerly winds helped bring
in a lot of new species, especially out west. I hope you students in the
Tucson, Arizona area haven't been inside the last few days because you
really would have missed out! I received reports of dozens of Wilson's
Warblers, Lucy's Warblers, and Black-throated-gray Warblers, as well the
first report of Scott's Oriole. Birders in southern California did pretty
well too, seeing their first Wilson's Warblers, Black-throated-gray Warblers,
Bullock's Orioles, and Western Kingbirds.
It was a pretty good week in the eastern US as well, with people along
the Alabama coast seeing the most. They reported seeing many White-eyed
Vireos, Worm-eating Warblers, and Ruby-throated Hummingbirds, and people
in Louisiana reported their first Indigo Buntings. Here in Tennessee, the
first Purple Martins showed up at my study site, and I heard the first
Blue-headed Vireo of the season. Blue-headed Vireos also showed up in both
Carolinas. The southerly winds have also helped push the first Tree Swallows
and Northern Rough-winged Swallows up into Pennsylvania.
Does This Week’s Weather Mean for Migration?
So will this week be just as productive? Look at the weather map and
There is a storm system in the middle of the country,
and you know what that means...bad flying weather. The rain will
ground birds for a couple of days as it moves across the middle and
eastern part of the country.
The high-pressure area behind the system will provide
clear skies, but north winds, so that will further delay migration.
All those birds I mentioned from the Gulf Coast will have to stick
around until the weekend.
Birds in the Eastern US had better get a move
on, otherwise they will be grounded starting at the end of the
week, and they probably
won't be able to head north again until the beginning of next week.
By that time, winds will be southerly in the central US, so birds
already here can get going again, and a new round of migrants can
Out West, the winds are already from the south. They
should stay that way for at least the next several days. That means
people farther north might see their first migrants, and people in
New Mexico, Arizona, and southern California should keep their eyes
open for more new arrivals from the tropics.
looks like migration is in full swing, so don't miss out! Take care.
