re: Oh yeah, I just noticed the foot thing. I was orginally drawing the legs at a different angle where only two of the toes were visible, I forgot to change the Chickadee's feet lol.
Although not all birds have three toes on the front. There are some birds that have zygodactyl feet, meaning they have two twos pointing forward and two pointing backward used to grip and climb. They can be seen on Toucans and Woodpeckers.
