Life Histories Of North American Nuthatches, Wrens, Thrashers And Their Allies: Order Passeriformes, Arthur Cleveland Bent
Life Histories Of North American Nuthatches, Wrens, Thrashers And Their Allies: Order Passeriformes, Arthur Cleveland Bent
Papers in Ornithology
An attempt has been made to give as full a life history as possible of the best-known subspecies of each species and to avoid duplication by writing briefly of the others and giving only the characters of the subspecies, its range, and any -habits peculiar to it. In many cases certain habits, probably common to the species as a whole, have been recorded for only one subspecies. Such habits are mentioned under the subspecies on which the observations were made. The distribution gives the range of the species as a whole, with only rough outlines of the ranges of the …
A Preliminary Study Of A Physical Basis Of Bird Navigation, Henry L. Yeagley
A Preliminary Study Of A Physical Basis Of Bird Navigation, Henry L. Yeagley
Papers in Ornithology
The bird navigation theory as presented implies an organ or organs in the bird's physiology which are sensitive to the effect of its motion through the vertical component of the earth's magnetic field and to the effort exerted to overcome the coriolis force, due to the earth's rotation. Both these influences involve a set of lines which together form a navigational gridwork. By correlating its instantaneous land speed with the two above effects, a bird can fly to its home which is a unique point in this gridwork, or to related companion points existing in the gridwork at positions other …

A Seasonal Study Of Food Of Some Birds Of The Wasatch Chaparral, Herbert H. Frost
A Seasonal Study Of Food Of Some Birds Of The Wasatch Chaparral, Herbert H. Frost
Theses and Dissertations
A seasonal change occurred in the type of food consumed by the birds studied. Plant food was more important in the winter than in the summer. Animal food, except in one species, was found to be more important during the summer months. The most important plant foods determined by frequency and listed in order of their abundance were: Helianthus annuus, Celtis sp., Quercus sp., Polygonum convolvulus, Amaranthus blitoides, Chenopodium album, and Amaranthus graecizans. The most important animal foods based on occurance in stomachs examined were: Coleoptera, Hymenoptera, Lepidoptera larvae, Orthoptera, Undetermined larvae, Diptera, Homoptera, Coleoptera larvae, Araneae, and Hemiptera.
