Coal Tit

Hello everyone. I first spotted this coal tit in our garden about a year ago and managed to take some photos of it yesterday. I thought it had part of its left leg missing, but looking at the photos it seems its leg is fine, it just doesn't have toes on that leg.

Was it injured or did its toes not develop properly?

The coal tit seems fine, I'm just curious. Slight smile

The first photo is a bit blurry, but it's the only one where you can see its left leg.
