Instructions
Take a look at the baby bird's feathers. Carefully observe whether the bird has feathers or down (a layer of fine fluffy feathers). Then, look to see if the bird has patches of feathers or down, or if its covered completely in them. Some baby birds may also be naked --- having no feathers or down at all.
Note the colors of the baby bird's feathers or down. Some birds, like the starling, will have a uniform color in a dark or light shade. Other birds, like the house sparrow, will have spotted or mottled feathers. Birds, like the cuckoo, may also have a two-toned coloring (dark on the back side and light on its belly).
Observe the shape of the baby bird's feet. Does the bird have webbed feet like those on a duck? Or sharp talons like a hawk? Or does it have separated toes unconnected by skin?
Find any unique characteristics. Some baby birds will have a special feature that distinguishes themselves from other species. Look closely at the bird to try to find a unique trait, like a hooked beak, spiky down its head, or completely black feathers. For instance, baby shorebirds will have unusually long legs.
Visit BabyBirdID.com to identify your baby bird. The site will ask you to fill out a brief questionnaire before it provides you with a list of possible bird species. (see Reference 1) Scroll through the pictures and descriptions until you find the species of your bird.
How to Identify Baby Birds
Baby birds can be difficult to identify, especially since they rarely resemble the adults of their species. Many baby birds have drab-colored feathers too that helps them hide from predators, but makes them tough to classify. If you would like to identify a baby bird, take note of its color, feathers, and the shape of its toes. Keep in mind though: Stay a safe distance from the baby bird unless it looks injured. Oftentimes, young birds will leave the nest before they learn how to fly, but their parents will still be nearby.
