🪶It was banded on the island of Rota in the western Pacific by Lauren as part of IBP's Pacific Islands Bird Conservation program: birdpop.org/pages/pa... 2/2

Photo by Lauren Helton of a Micronesian Rufous Fantail being held by a certified and permitted bander. Text on the photo says "My, what fabulous rictal bristles you have!" with an arrow pointing to the bristles that says "check out those bristles"

🪶The "rictal bristles" around this Micronesian Rufous Fantail's beak act like a catcher's mitt to help the bird catch insects in its mouth. This species hunts insects in the understory of tropical woodlands and its large eyes help it see in the shady conditions. 1/2

In hand photo of a Micronesian Rufous Fantail, a delicate little songbird with a rich red-orange brow, white throat, spotted black collar, and big black eyes.

Back to setting up a banding crew on Rota, where only perfect birds exist.

Photo of a female Williamson's Sapsucker perched on a tree trunk with wings spread by Brooke Miller. Text on graphic says: Aske Peter- One or Two Wintering Williamson's Sapsuckers?

Can you tell how old this sapsucker is by looking at this photo? IBP biologist Peter Pyle can! In our latest blog post he uses his feather aging skills to determine if a vagrant Williamson's Sapsucker in the Bay Area is a repeat winter visitor. Read it here: https://bit.ly/4rpBHep 🪶

Photo of a Townsend's Solitaire perched at the top of a juniper by Charles Gates. Text on the photo says "Unsolicited Bird Fact: If Townsend's Solitaires drank cocktails, their drink of choice would probably be a gin and tonic. During the winter they eat almost exclusively juniper berries. During the breeding season, solitaires move into higher elevation (or latitude) coniferous forests where they feed primarily on insects. If we knew anything we'd make a gin and name it after these elegant birds.

Did you ask for a bird fact? No, but you're getting one whether you like it or not. 🪶

Photo of an Osprey perched above a nest on a platform with powerlines in the background.

Our comms specialist saw her FOY (first-of-the-year) Osprey in western Colorado today. Have you seen any FOY migratory birds yet? 🪶

That makes a little more sense. We could see them poking their bills in cow-pies for bugs maybe.

Cormies are so beautiful close up. The first time I really saw a double-crested's eyes, I think I gasped, because they are so rarely presented as pretty birds. You look this good, you can have all the fish.

A brownish gray bird with white spots on the back, is held in a human hand with one blue wing extended.

A blue bird with an orange breast and white belly is held on it's back in a human hand. One foot is extended while the leg diameter is measured with a tool. A toolbox with bird banding tools is in the background.

Long term bird banding tells us which #birds are present & pop. & demography trends. Since 2021 we've banded birds in the #Baraboo Hills. Data go to @instbirdpop.bsky.social supporting knowledge of local & regional birds.

Turns out penguins do have knees. They're just not where you think they ought to be.

🪶Some bird fun for Monday

"But as the feathers age, those tips wear off, and the more brilliant coloring emerges, often in time to look especially attractive when breeding season arrives. " 2/2 🪶

🪶 Nobody guessed it! We chose this photo because it was interesting how much gray and buff was on the body coverts. Our banding queen Dani K. says "sometimes birds have lighter tipping to their feathers when they grow in, e.g., robins or starlings...1/2"

After a Devastating Bird Flu Outbreak, Scotland's Seabirds Are Slowly Recovering—and So Are the Scientists Who Witnessed Their Decline The world’s largest colony of northern gannets was decimated by bird flu in 2022. Now, as their numbers climb again, researchers are collecting data to understand the virus’ lasting effects

My story for @biographic.bsky.social on the aftermath of HPAI in Northern Gannett colonies was picked up by Smithsonian Magazine! A nice thing to see while resurfacing briefly during another round of kid sick days...

Chart featuring the heads of ten Northern Flickers. Text at top reads "October 2025-February 2026 intergrade and aberrant Northern Flickers". Each individual flicker is illustrated with its unique head pattern, including moustache color, face color, crown color, and presence or absence of red on the nape. Each bird also has a date it was first recorded (month and year), is marked male or female, and has a swatch showing the underwing color. There are five females and five males and each one of them is distinctly identifiable because of its combination of traits.

Here's this winter's full cast of characters! Lots of new intergrade N. Flickers at my backyard feeders this year, not so many returning from previous years, though there are a few. "Yellow" has been an especially unusual standout.

See reply for what makes these birds special.
