by my assessment, for the southeastern part of Louisiana, peak Ruby-throated Hummingbird movement is generally around the second to the third week of September and it drops off sharply after that. I have been away and otherwise preoccupied for much of September, so banding chores have fallen on my assistants, only one of whom is permitted to band.
At my place, I have been running 3 to 5 feeders since returning from Florida in July. Since then, I have observed only 3 or 4 individuals to make use of the feeders. Mostly, these transients are enjoying the natural nectar of red Firespike [Odontonema strictum
'Phyllis's Fancy', Ugly Shrimp Plant [Justicia brandegeena
], Canna [Canna indica
], and Baja Fairy Duster [Calliandra californica
], Turk's Cap [Malvaviscus drummondii
] and the two little flowered morning glories [Ipomoea hederifolia
] and [Ipomoea hederifolia var luteola
]. There are usually several clouds of tiny flying insects and the birds can sometimes be observed to dance around snatching the little bugs from the air.
On Saturday, our team banded at the Feliciana Hummingbird Celebration in scenic St Francisville. We handled 45 individuals [will add breakdown by age and sex when I get the data sheets from our recorder]. Around 400 interested observers visited the site. Here is a video made by one of our guests: https://www.youtube.com/watch?v=udF2cNjQ9IE&feature=youtu.be
On Sunday, we banded at our regular site in Covington, where there were perhaps 25 invited guests, and we caught 44 birds: 8 adult males + 7 adult females + 19 immature males + 10 immature females, plus an estimated 16 that we did not catch.
Tomorrow, I will be working with another bander to demonstrate what we do for a university wildlife management class.
So far, I have not seen any other species though a few of our sites have reported probable returnee Rufous and Buff-bellieds. I look forward to September - and I dread it, too. Edited in: I've gotten 2 reports of Rufous Hummingbirds since I originally posted this message!
