Summer conditions continued through the last two days with temperatures in the mid- to high-20s by the early afternoon. Each morning has been relatively cool and the resulting fog not only waters the plants (the trees drip until 9 or 10) but coats the innumerable spider webs that festoon the site. A formidable gauntlet for the small insects.


There has been a slow but steady flow of birds through the site:

Another hot, muggy day; the only difference to those of the past week is that there were clouds, sometimes covering a much as 75% of the sky. I was hoping for a little rain some sort of hint that amelioration of this wave might be lessening….As the day progressed the cloud dissipated and the heat rose into the high 20’s.

But there was a discernible change: while Bobolinks were still present (a flock of 12 was taking advantage of the prairie grass seeds) some new migrants found their way into the nets: an early White-crowned Sparrow, Swainson’s Thrush, Western Palm Warbler, and Bay-breasted Warbler. I wonder what impact this prolonged heat has on them…?

It’s been a strange week, meteorologically speaking: daytime temperatures in the mid- to high-20’s; cloudless skies, and almost no wind. Summer conditions. I’m looking forward to the Fall with its cooler temperatures and flushes of migrants. The only thing that even hints of Fall at the moment is the falling of leaves. The black walnuts are dropping their foliage. It has a rather peaceful effect actually. Sitting their, scanning the upper branches for migrants, the regularly falling leaves seem like a gentle snowfall. In some ways the lack of wind at this time of year is a good thing as most of these falling leaves miss the nets. When the wind blows they fill up and it can take a lot of time and dexterity to remove them at closing time. [BTW the leaf extraction record is help by Elaine Serena and myself when it took us an hour and a half to clear a double net of walnut leaves in order to close it.]

Birds seem to arrive (and then leave) in pulses; some days are better than others both in terms of numbers banded and in the number of species observed. In the latter regard, we have seen VERY few warblers and other migrants but on Saturday (14th) we encountered 46 species including 9 firsts (for us) for the season: Pied-billed Grebe, Philadelphia Vireo, Veery, Swainson’s Thrush, Gray-cheeked Thrush, Bay-breasted Warbler, Blackburnian Warbler, Black-throated Green Warbler, Wilson’s Warbler. Alas, except for the Wilson’s Warbler which we caught, the other warblers were feeding high in the willows.

Following are our totals for the week. Note the up’s and down’s….

We are getting a fair number of “retraps” – birds that we’ve usually just banded over the last couple of weeks and that are staying around. Most are young of the year that are going through a moult while they also check out the possibilities of the area for potential nesting territories next Spring. The weather is such that they don’t seem to feel much urgency to hurry south…and there’s lots of food here. Today, for example, while we banded only 9 birds, we handled 19 retraps.

We’ve been busy, banding on 6 of the last 7 days. Each day is different both in terms of numbers banded and in the variety of birds seen at the site. But two species have been consistent: Bobolinks and Indigo Buntings. Part of the prairie field was mown with a wide swath left down the middle (more or less) and another along the pond/woodland edge. We cut 2 net lanes through the middle swath and they have been very effective catching Bobolinks and, to a lesser degree, Indigo Buntings – we’re also picking the latter up in nets along the edge. Both species are seed-eaters; the Bobolinks are fattening up for the long journey to Argentina and the buntings are finishing off their moults before heading for southern Florida and Central America.

And the field has LOTS of food!


Below, to simplify things (for me), I’ll list the birds banded each day and throw in a few pictures. We’ve had a number of very helpful volunteers…who also take good photos.
