The bones and hair of the small mammals eaten by Owls are rolled into

oblong pellets in the stomach and are ejected at the mouth. These

pellets may often be found in large numbers beneath the roosts in

which Owls pass the day. In 200 such castings of the Barn Owl Dr.

Fisher found the remains of 454 small mammals of which no less than

225 were meadow mice.

Hawks build large-bulky nests of sticks placing them usually well up

in large trees, and lay, as a rule, four eggs which are generally

whitish, blotched with brown. The Marsh Hawk is an exception. Its nest

built largely of grasses, is placed on the ground in marshes and the

eggs, often numbering six and rarely eight, are bluish white unmarked.

The Owls nest in holes in trees or banks, or, in some instances, an

old Hawk or Crow nest may be occupied. The eggs usually number three

to five and are always pure white.
