Ruby-crowned Kinglet (Corthylio calendula)

"Silly little guy :)" "A bouncy, quick little bird with an neat red crest that is usually hidden"

I don't think you get how small this bird is. Its mouse sized- its probably smaller than mouse sized! The RCKIs (rickys, as we affectionately call them) I have banded typically weigh 6g. A medium-sized hummingbird is like 3.5g. They're almost hummingbird sized, and they overwinter in parts of Canada and North America that still regularly receive heavy snowfall! What the heck??

Their songs are too big for their body, too. When you hear their song you'd expect to see a sparrow sized bird, perhaps, or at least a warbler up there in the treetops, but no, its a Ricky, hanging out in the shrubs beside you while he picks off tiny bugs and then turns around and belts another beautiful tune.

A Warbler's Tale

Correction: This bird is a pine warbler (Setophaga pinus).

I believe this is a female ruby crowned kinglet (Corthylio calendula). Merlin identifies it as a Bell's vireo, but I think that the beak and eye are a bit off for a vireo, plus this we're not in the range for the Bell's vireo. My confidence level is about 80% on this ID, so I'm open to other opinions.

"The Ruby-crowned Kinglet is a tiny bird that lays a very large clutch of eggs—there can be up to 12 in a single nest. Although the eggs themselves weigh only about a fiftieth of an ounce, an entire clutch can weigh as much as the female herself." - allaboutbirds.org

Chadron State Park - Fall 2023

THE Smallest Bird! Absolutely Tiny! Ruby-crowned Kinglets are the smallest birds I have ever banded in my life (as I've not banded a hummingbird... yet)! The majority of songbirds moving through the station weigh in between 10-15g. Kinglets, on average, weigh 6g. That's the same as a US quarter. Can you believe that??

Even more wild is that kinglet don't seem to mind the winter weather the same as other songbirds, and will overwinter further north than you would expect such a little guy to do! They stay as active as possible to keep warm, picking what tiny bugs they can find.

The "ruby-crown" in question is absent from this bird, as she was a young female, but even if she had a full crest it wouldn't be evident in a picture like this. The male's crown is able to be hidden beneath their head feathers, only to be flaired during mating displays or territory disputes.

All banding, marking, and sampling is being conducted under a federally authorized Bird Banding Permit issued by the U.S. Geological Survey's BBL. Permission to share images was granted by Bird Conservancy of the Rockies (BCR).
