Another very quiet week, with not many migrants around. A higher percentage of the young resident birds that I'm banding have not yet started or are just beginning their post-juvenile molt than I usually see this time of year. This is the replacement of their juvenile plumage into their first winter adult plumage. It's usually in full swing right now. Same with the molt of adults, who typically molt all of their feathers after they are done nesting. The adults I've banded have just started this process.
The extent of this molt this year tells me that these species -- cardinals, catbirds, robins, and Song Sparrows mostly -- were a little later in fledging than usual. It could be that the big flood in May caused some birds to lose their first nest, and pushed breeding back a couple weeks. Or, good conditions this summer (warm, good amount of rainfall, lots of bugs) could mean some species attempted a third nesting.
I have heard and seen adult birds still tending their newly-fledged young. Here is a brand-new youngster I captured this week. Can you guess the species?
Another frequent nester is the Baltimore Oriole. Because they migrate so early in the season, I sometimes don't catch any in the fall. I had three in one net this week, including this adult male. Orioles are pretty sassy. This one seemed astonished, and a little indignant.
