Hummingbird Info π
We recently posted an image of an old adult Ruby-throated Hummingbird (see our timeline below) whose otherwise-white gorget was marked by numerous dark streaks--somewhat unusual for a female. Today (9 June 2023) at Hilton Pond Center we netted another streak-throated hummer (see attached photo) whose appearance told us two things: 1) a yellow gape identified it as a recent fledgling, and 2) extensive dark streaking meant it was almost certainly a young male--a supposition borne out by measurements.
Today's bird was tied for the Center's fourth-earliest-record for a fledgling RTHU; previous June dates include the 4th, 5th, 6th, and 9th (three birds). A more typical date is 1 July, which suggests ruby-throats got a very good start on breeding this year.
It's also worth noting today's capture was the 39th RTHU banded in 2023, our second-fastest year since 1984 to reach that number. Even more significant, we've also recaptured 51 "old" ruby-throats banded in previous years. This is our fourth-highest annual total for returns, with a long way to go before the end of the season. (Previous marks: 62, 58, and 56.)
With all this in mind, things look very good for local Ruby-throated Hummingbirds in 2023. Lots of new adults plus a ton of returns equals a potential for a good crop of fledglings, and maybe even double-brooding. This may be the year we go broke buying sugar!
