1.) Wings flapping, markers attached to arm

2.) Pull tail or activate arm with hinges,

1.) Peregrine Falcon   source

- It lives in the open country, cliffs (mountains to coast); sometimes cities. Over its wide range, found in wide variety of open habitats, from tundra to desert mountains. Often near water, especially along the coasts, and migrants may fly far out to sea.

- One of the world's fastest birds; in power-diving from great heights to strike prey, the Peregrine may possibly reach 200 miles per hour. 

- Often hunts by flying very high, then stooping in spectacular dive to strike prey out of the air. Large prey may be knocked out of the air, fed upon on the ground where it falls.

- It eats mostly birds. Feeds on a wide variety of birds. 

- Pigeons are often favored prey around cities, and ducks and shorebirds often taken along coast; known to take prey as large as loons, geese, large gulls, and as small as songbirds. 

- Also eats a few small mammals, seldom insects, rarely carrion.

- It is very territorial and courtship displays include high circling flight by male, spectacular dives and chases by both sexes. 

- Male feeds female. Breeding Peregrines defend the immediate area of the nest from intruders, but hunt over a much larger area. 

- Nest site is usually on cliff ledge, sometimes in hollow of broken-off tree snag or in old stick nest of other large bird in tree.
