The molt goes on...

Birding at Voice of America (VOA) Park near Mason, OH
..continued from a post last week on a male Bobolink molting into his Basic non-breeding plumage at VOA Park.
I stopped by the park late friday afternoon to see how far along the male Bobolinks were in their molts. It had only been five days since I was last there, but boy had they changed!

He has lost almost 50% of his black
feathers. The change is fairly quick!

If you look closely, you can see he is losing
the pigment in his bill. It's mottled black now.

Check my other side...I'm quite handsome in
my "tortie-shell transition phase."

He will molt all of his feathers including flight and
tail feathers. He does not lose them all at once,
so he is never rendered completely flightless



While walking through the mowed areas of the meadow, I heard three Henslow's Sparrows in the middle...and a single Henslow's Sparrow in the area closest to the little parking spot by the big tree. There were also five Willow Flycatchers hawking insects using the big tree as a base. If you want to learn more about the Henslow's Sparrows of VOA, head over to my friend's new blog, Everybody Funny. He surveyed VOA from 2001 to 2007 weekly and accumulated a lot of research on the Henslow's Sparrows nesting there.

Male Bobolink starting to molt into his non-breeding Basic plumage

Birding at Voice of America (VOA) Park near Mason, OH
...continued from the Henslow's Sparrow post.
Before fall migration coaxes Bobolinks south to their wintering grounds, male Bobolinks start molting into non-breeding Basic plumage. It’s almost like the males shed their formal “tuxedos” for more relaxed and casual traveling clothes. The following male Bobolink is just starting to molt into his Basic plumage. By the time he’s ready to fly south, he will more closely resemble the understated females.

Looking a little scruffy, this male Bobolink
has started molting into his Basic plumage.
He was singing just as sweetly, but maybe
not quite as often as earlier this summer.
He did a lot of calling instead.

In addition to their molt into non-breeding
plumage, male Bobolinks will lose the
dark pigmentation in their bills.

He looks like he's ready to fly south right now!

A female Bobolink perched on a sapling--her
warm caramels and browns are every bit
as appealing as the male's flashy summer
tuxedo. In the fall, the male Bobolink
takes on the female's casual colors.

Sitting in the fading light, the female was gorgeous.
I need to go back and capture her in full sunlight.
