Migrants, migrants everywhere! Here’s a look back:
The southerly winds all week have really been bringing in a lot of migrants.
There are reports from all over the country of good numbers of migrating
birds. People along the Texas coast have been seeing lots of Black-throated-green
Warblers, as well as the first Worm-eating, Blue-winged, and Kentucky Warblers,
Summer Tanagers, Scarlet Tanagers, Orchard Orioles, and Wood Thrushes.
Along the Alabama coast, there were reports of lots of different vireos,
along with good numbers of Ruby-throated Hummingbirds, and the first Blue
Grosbeak of the season. Coastal Georgia had many Northern Parulas, while
people in North Carolina reported lots of Blue-headed Vireos. Here in Tennessee,
there have been lots of Blue-gray Gnatcatchers at my study site, along
with the first White-eyed Vireo of the year. A birder up at Frozen Head
State Park saw 38 (!) Black-throated-green Warblers, as well as the first
The strong southerly winds have allowed many migrants to make a lot
of progress northward. Pennsylvania and Ohio had their first
gnatcatchers, Yellow-throated Warblers, and Louisiana Waterthrushes.
Missouri reported their first Northern Parulas and Hooded Warblers,
while the first
White-eyed Vireo was seen in Central Park, and Tree Swallows have made
it as far north as Massachusetts!
Birders out West haven't been disappointed either. The southerly winds
have brought plenty of migrants their way as well. Several places in
New Mexico reported many Cave Swallows, along with White-throated Swifts,
Kingbirds, the first Bell's Vireos, Lucy's Warblers, and Bullock's Orioles.
The situation was similar in Arizona, with reports of Lucy's, Wilson's,
and Yellow Warblers, along with Cassin's Kingbirds and Bullock's Orioles.
An Orange-crowned Warbler was seen in Nevada as well. See? Not many people
Does This Week’s Weather Mean for Migration?
You should be getting comfortable reading a weather map by now. Last
week, I mentioned a front that might force migrants to land. Well, that
front weakened and so didn't have much effect. This week is different.
Take a look at the map:
A couple of strong storm systems are moving across
the country. Over the next couple of days, those systems will bring
storms and northerly winds to the central US and Gulf coast. That
means migrants will be forced to land for a few days, so the fallout
chances look good.
By the end of the week, the same thing will happen
in the eastern part of the country. The winds farther west will
have shifted to
the south by that time, so birds should have good flying weather
and could make it up through the Great Plains, Midwest, and maybe
even the Great Lakes region.
Farther to the west, the storm systems
have already cleared out, so the winds should shift to the south
in another day or
will allow a new batch of migrants to come in, and other
to make it farther north.
give you an idea of what is in store, a birder from Alabama submitted
a report from the Yucatan Peninsula in Mexico. This is the point from
where many migrants take off to cross the Gulf of Mexico and reach the
southern US. He reported large numbers of Blue Grosbeaks and Orchard
Orioles, and while numbers were not as high, he also saw a dozen species
of warblers. This could be a good week, and we are still early in migration!
