Summary

Alice Hall Walter Wild Birds in City Parks

The identification of birds depends quite as much upon accurate observation of their size, motions, flight, characteristic attitudes, manner of feeding, company, song, call-notes and haunts, as upon details of form and color. Especial care is necessary to insure correct estimates of size for the reason that living birds often appear smaller to the unpracticed eye than they actually are. The familiar English Sparrow is a convenient standard of size because it is usually at hand in our city parks for instant reference.

It is, of course, neither a warbler nor a vireo for these birds, although active and frequenting trees, arrive much later in the spring. Provided it does not brace its tail and climb up and around the trunk of the tree it is not likely to be a woodpecker, because the motions of woodpeckers are too characteristic to be mistaken. In similar manner, although sparrows and juncos may have arrived, it is probably neither of these since it does not feed upon the ground, while its size precludes the possibility of its being any bird larger than the English Sparrow.

Ducks, Geese and Swans have webbed feet and short legs, and in walking carry themselves almost horizontal. As a rule they have very strong wings, enabling them to fly long distances at great speed. Our ducks are most easily remembered in three groups:—
1. The fish-eating Mergansers, whose plumage is largely black and white and which have saw-edged bills and, usually, conspicuous crests.
2. The Sea Ducks, which are conspicuously marked but plainly colored, frequent open water or the sea coast, diving, often to great depths, for their food.
