HOLIDAYS WITH HUMMING BIRDS A BABY HUMMING BIRD, WITH OUTSPREAD WINGS, BEGGING TO BE FED Like most young birds, baby Hummers have an appetite quite out of proportion to their diminutive size. The parents feed them by regurgitation, first swallowing and partially digesting the food themselves. To the uninitiated, the old birds appear to be attacking their offspring when they are in reality supplying them with predigested nourishment (see text, page 739). DINING WHILE RECLINING-A RARE POSE While our well-known Ruby-throat varies from three to four inches over all, in the West Indies there is a species only 2/4 inches in length; on the other hand, among the high Andes one variety of Humming Bird is as large as our unwelcome Starling. A long bill is a feature common to Hummers, and in one species the bill is longer than all the rest of the bird.
