Most descriptions of the circulatory system of birds, largely the work of Glenny, have dealt with arteries of the neck and thorax in a wide variety of species.

In his _Manual of Psychology_ Dr Stout reminds us that “Human language is especially constructed to describe the mental states of human beings, and this means that it is especially constructed so as to mislead us when we attempt to describe the working of minds that differ in a great degree from the human.” The […]

Because its unique geographical location and ecological setting supports a rich and varied avifauna, the Yucatán Peninsula has received considerable attention by ornithologists. The most valuable contribution is Paynter’s “The Ornithogeography of the Yucatán Peninsula” (1955a), an authoritative study of the composition, distribution, and origin of the avifauna of the region.
