Unlike most owls, Barn Owls don't engage in mellow nighttime “hooting ” they pierce the darkness with long, harsh screeches. The orientation of the toes, the size of the talons and how a bird uses its feet are also useful identification characteristics.Barn Owl. Feet: Many birds' feet are the same color as their legs, but not always.Some raptors, for example, have heavily feathered legs that can be used to identify the birds. The thickness of the leg, while difficult to see on many species, can also be a clue, as can any feathering. Legs: Birds' legs vary in length and color, both of which can be useful field marks for proper identification.Undertail coverts: The short feathers beneath the tail are the undertail coverts, and these feathers often show unique colors or markings that can distinguish bird species.The tail can be held in different positions when the bird is perched or flying, however, and watching for different markings can help distinguish different birds. Tail: The length, shape and colors of a bird's tail are important for proper identification.For many birds, the rump does not stand out, but some species show unique rump color patches that are useful for identification.
#LATE BIRD DEFINTION PATCH#
Rump: A bird's rump is the patch above the tail and low on the back.In flight, wing shape is also a great field mark. Wing bars or patches are useful field marks, as are the lengths of the wings compared to the length of the tail when the bird is perched. Wings: Birds' wings are their upper limbs used for flight.In many bird species, the flanks have unique colors or markings, though depending on how the birds carry their wings, the flanks may be difficult to see. Flanks: The flanks (sides) of a bird are located between the underside of the wings and the abdomen.The colors and markings on the abdomen may vary from the chest and flanks, making it a good feature to check for identification. Abdomen: The abdomen or belly of a bird extends from the bottom of the chest to the undertail coverts.A bird's chest may be differently colored or marked with stripes, streaks or spots that can help with identification. Chest: The chest (also called the breast) is the upright part of the bird's body between the throat and the abdomen.Look for different colors and markings along the back that distinguish it from the neck, rump and wings. Back: A bird's back is often broad and easy to see in the right posture.The length of the neck can also help distinguish different bird species.
On wading birds, however, the neck is much more prominent and can be a good place to look for field marks.
