I like puffy birds. Birds that are puffed-up seemingly against the cold are adorable. Here is a collection of such birds.

This Ruby-crowned Kinglet does not appear in the Bird Species List as a representative example.
I love this photograph, even though it is a bit blurry. I have never seen a bird puff up this much. I was shooting this Ruby-crowned Kinglet hopping around a bush and didn’t notice him get puffy (my other shots were more normal). When I was reviewing my photographs of the day I started laughing when I saw this one. While not the representative image for the day, I knew I had to share it, so this bird is where the idea for the Puffy Birds collection came from.

This Carolina Chickadee was one of the first puffy birds I photographed, and probably the one that endeared me to them. I may have better Carolina Chickadee photos, but I like it so much it remains (at the time I put this list together) as my species representative photograph.

This guy let me hang around for a long time while he was hunting. Most of the time he was not this puffy. He flew across the trail to scope out a different field, and after he landed he looked like this. So I took a few more shots and then left him alone to find his breakfast.

Owls are sort of puffy to begin with, but this Barred Owl was the puffiest owl I have seen. We heard this owl (and a few others as they would call to each other) often during the four years we lived in Western Kentucky and I was very lucky to get a shot of it almost out our back door.

This puffy Brown Thrasher stayed near me for quite a while, just a few feet away. He liked posing which worked well as I liked taking his picture.

Although not a puffy as some, this Eastern Phoebe was puffy enough to be included. She was so cute sitting on this branch and I am fortunate to have been able to catch her in a photograph.

It was a very cold morning as I was walking along the fence row at the Village Creek Drying Beds. This adorable White-throated Sparrow was perched near the fence and was flitting around a bit. He finally settled down enough for me to get this photo with him looking so cute.

This White-winged Dove was the first puffy bird with my new lens. It was unusually cold and cloudy that day and this dove was certainly feeling it.

This Carolina Wren spent most of the time I was taking over 100 photographs of it singing. For a brief time he stopped singing and puffed up on this cold February morning.

I was walking along a trail, still on a natural high from seeing and photographing a Barred Owl when I saw this Northern Cardinal all puffed up. It was a cool morning, but definitely not cold and it was getting warmer. Still, he was perched there looking gorgeous.

Originally I thought this yellow bird flitting around so rapidly (and at a decent distance) was an American Goldfinch. I was surprised when I got home and saw the pictures that it was a White-eyed Vireo. With it, and a few others I saw that weekend, the spring migration north is in full force. I was happy to see one of the shots has this bird in puffed-up mode.

Here is another White-eyed Vireo. This guy was defending his territory from another White-eyed Vireo. I guess he is trying to look bigger by puffing up. The shot was very quickly taken, so it is not as sharp as I would like, but actually ended up better than I thought when I first took the picture.
