[13] There is some sexual dimorphism in both plumage and dimensions, the female having a smaller bill and paler, more barred undersides. A juvenile, displaying the pale tipped feathers on the wings.

This can make the bird a nuisance when it chooses to roost in populated urban spots such as golf courses or schools. Mississippi kites protect their nests by diving at perceived threats, including humans; however, this occurs in less than 20% of nests. Staying at least 50 yards from nests is the best way to avoid conflict with the birds.

Flight feathers (Pennae volatus) [1] are the long, stiff, asymmetrically shaped, but symmetrically paired pennaceous feathers on the wings or tail of a bird; those on the wings are called remiges (/ ˈ r ɛ m ɪ dʒ iː z /), singular remex (/ ˈ r iː m ɛ k s /), while those on the tail are called rectrices (/ ˈ r ɛ k t r ...

Bird flight includes multiple types of motion, including hovering, taking off, and landing, involving many complex movements.
The narrow sickle-shaped wings of the swift are longer than its body, and its silhouette in the air resembles an anchor. The swift's wingbeats are deep and quick, and the swift glides for longer. The swallow's flight is more fluttering, and it presses its wings further to the rear during beats.
