Not all bird feet are alike, even toe shape and placement can vary. One example of different toe alignment seen in birds is being zygodactyl, where two toes face forward and the other two face backwards. This can be seen in species such as woodpeckers, parrots and owls. This arrangement of toes is perfect for…

Bird Adaptations: Woodpecker’s Tail
When you see a woodpecker, they are typically clinging onto the bark of a tree or branches, usually using their tail to prop themselves up. This position would typically put a lot of pressure and wear on their longest tail feathers. Because of this risk of increased damage to these feathers, they have a special…

Term: Dihedral

These feather patterns aren’t eyes though, they are called ocelli, or false eye spots. This adaptation can…
Bird Anatomy: Nictitating Membrane
For birds to survive, they need keen eyesight, to find food, to navigate their environment, find a mate and avoiding becoming something else’s meal. So it is critical to protect their eyes, especially when flying through the air and through vegetation where there is an increased risk of something hitting their eyes and causing abrasions….
Bird Anatomy: Supraorbital Ridge
Birds of prey have excellent vision, they need it to be able to see prey from perched in a tree or soaring high above the ground. Though, something can get in the way of their vision, making it difficult to clearly see, especially when out in the open, and that is the sun. Many times…
Bird Anatomy: Lamellae
If you look at the bills of some duck species, you may see it lined with fine comb-like structures. These little projections are called lamellae and are made of keratin. These slightly flexible structures are used to filter and strain food from mud or water. These structures will be seen mostly in dabbling ducks along…
Bird Anatomy: Tomial Tooth
The tomial tooth, or the mandibular tomia, is not really a tooth at all, but a projection that can be seen in the outer edge on beaks of falcons, kites, and shrikes. This “tooth” also corresponds with a divot on the lower bill, called the mandibular notch; these together act like a pair of scissors…
