Behavior Of The Red-Footed Booby (Sulasula) In British Honduras, Jared Verner
Behavior Of The Red-Footed Booby (Sulasula) In British Honduras, Jared Verner
LSU Historical Dissertations and Theses
During three months of the breeding season in a colony of 3500 Red-footed Boobies (Sula sula) on 45½-acre Half Moon Caye, fifty miles east of Belize, British Honduras, that species’ little-known breeding activities were investigated. Feeding flights of boobies began leaving the caye before daylight and returned in the evening until after dark. Wind direction and velocity notably affected the mode of the birds’ departure but little affected their direction. Average flight-unit size was 2.41 birds. Contrary to published accounts, the boobies were able to take flight from the ground.

An Electrophoretic Study Of Egg-White Proteins In Twenty-Three Breeds Of The Domestic Fowl, Charles G. Sibley, Paul A. Johnsgard
Paul Johnsgard Collection
A "conservative" taxonomic character is one which preserves evidence of evolutionary relationships. As Mayr (1942: 296) points out such characters are rare because structures are usually lost quickly when no longer needed and selection seldom neglects a functional structure for very long but continually modifies it as adaptive fitness is increased. However, because different characters evolve at different rates it is possible to find some characters which have changed more slowly than others and to use these as phylogenetic indicators. In birds, for example, plumage color and structure apparently change more rapidly than the skeleton or the muscular system. This …
