Most perching birds (passerines) hop, though many can both hop and walk (such as ravens, blackbirds, and robins). Jays, sparrows, cardinals, titmice, nuthatches, finches, and many others hop. The tracks of hopping birds often print side-by-side as they tend to keep their feet together as they hop.

Walking birds include crows, most waterfowl and shore birds (sandpipers, egrets, herons, etc.), and most game birds (wild turkeys, geese, ducks, grouse, doves, pigeons, etc.). The tracks of walking birds typically alternate left to right as they lift their feet one at a time.

- Pellets: Birds of prey regurgitate the indigestible portions of their meals. Birds have no teeth so they rip their prey apart with their beaks and swallow large chunks at a time. Then they digest the soft portions (such as meat) leaving the hair and bones behind to collect into pellets. They cough up these pellets which can be found by the astute observer.

Hummingbird: During hovering, ruby-throated hummingbird wings beat 55 times per second, 61 times per second when moving backwards, and at least 75 times per second when moving forward.
Canadian geese can be identified from a great distance by their distinctive V formation.
