Mandibular Bowing and Mineralization in Brown Pelicans
Brown Pelicans (Pelecanus occidentalis) plunge dive into water to capture fish with highly distensible pouches. During prey capture, the pouch may expand to hold 11 L of water and the mandibular rami may bow from a resting position of 5 cm to over 15 cm. We compared mineralization of two bending regions of the mandible with a nonbending region, and examined cross-sectional morphology to determi...
متن کاملLz Where Pelicans Kiss Seals
he story of how children learn to seems at f i rs t be a simple one: At a very early age they begin by scribbling with any available marker on any available surface. At first the children’s drawings are simple, clumsy and unrealistic; gradually they become more technically skilled and realistic. But the development of drawing is not quite so simple and straightforward. In fact, the story turns ...
متن کاملCounting calories in cormorants: dynamic body acceleration predicts daily energy expenditure measured in pelagic cormorants.
The integral of the dynamic component of acceleration over time has been proposed as a measure of energy expenditure in wild animals. We tested that idea by attaching accelerometers to the tails of free-ranging pelagic cormorants (Phalacrocorax pelagicus) and simultaneously estimating energy expenditure using doubly labelled water. Two different formulations of dynamic body acceleration, [vecto...
متن کاملExperimental Bolbophorus damnificus (Digenea: Bolbophoridae) infections in piscivorous birds.
In order to determine potential definitive hosts of the digenetic trematode, Bolbophorus damnificus, two American White Pelicans (Pelecanus erythrorhynchos), two Double-crested Cormorants (Phalacrocorax auritus), two Great Blue Herons (Ardea herodias), and two Great Egrets (Ardea alba) were captured, treated with praziquantel, and fed channel catfish (Ictalurus punctatus) infected with B. damni...
متن کاملIsolation of Candida albicans and halophilic Vibrio spp. from aquatic birds in Connecticut and Florida.
Halophilic vibrios were recovered from feces of six types of aquatic birds (gulls, pelicans, Canada geese, swans, egrets, cormorants) from Connecticut and/or Florida shorelines. Candida albicans was isolated from gulls and Canada geese in Connecticut and from gulls and cormorants in Florida.
