Enteroparasites from the American White Pelican (Pelecanus erythrorhynchos) in Toluca Valley, Mexico

Journal of Wildlife Diseases, 2023
We examined 82 fresh fecal samples from American White Pelican (Pelecanus erythrorhynchos) at San Pablo Autopan, Toluca Valley, central Mexico, December 2021 to April 2022. Eggs of Contracaecum spp. were observed in 100%, Capillaria spp. in two (2.5%), Strongyloides spp. in eight (9.7%), and coccidial oocysts in 12 (15%).

Nocturnal Foraging in the American White Pelican

The Condor, 1992
Nocturnal foraging was examined in American White Pelicans (Pelecanus erythrorhynchos) at the Dauphin River, about 50 km from a breeding colony on Lake Winnipeg, Manitoba, Canada. From two to three times as many pelicans foraged at night as in the daytime, with foraging flocks being larger at night.

The Development of Endothermy in American White Pelicans

The Condor, 1999
We examined the development of endothermy in White Pelican (Pelecanus erythrorhynchos) chicks during the first 16 days after hatching, which corresponds with the age at which parent pelicans begin to cease brooding behavior. At ambient temperatures between 20 and 25°C, pelican chicks progressively increased their thermoregulatory capabilities with age;

Brood reduction in the American white pelican (Pelecanus erythrohynchos)

Behavioral Ecology and Sociobiology, 1986
American white pelicans (Pelecanus erythrorhynchos) breeding in colonies at East Shoal Lake, Manitoba, Canada exhibited a mean hatching asynchrony of 2.5 days in 2-egg clutches. This resulted in a size difference between chicks which facilitated sibling dominance, harassment and lack of food for the subordinate chick.

SUSPECTED FENBENDAZOLE TOXICITY IN AN AMERICAN WHITE PELICAN (PELECANUS ERYTHRORHYNCHOS)

Journal of Zoo and Wildlife Medicine, 2016
A wild-raised, 5.0-kg male American white pelican ( Pelecanus erythrorhynchos ) of unknown age presented for routine examination at both the start and completion of a 30-day quarantine period at a zoological park. Upon physical examination, the pelican was bright, alert, and responsive and in good body condition.

An Overview of the American White Pelican

Waterbirds, 2005
Abstract Comments on the American White Pelican (Pelecanus erythrorhynchos) in North America languished until Peter Ogden reported trapping one during his 1825 expedition to Utah. Brief accounts of the American White Pelican by ornithologists continued through the 1940s. In subsequent decades, scientific studies uncovered greater details of the species'

American White Pelican Predation on Cui-ui in Pyramid Lake, Nevada

North American Journal of Fisheries Management, 2014
Abstract Anthropogenic changes to the Pyramid Lake–Truckee River ecosystem in Nevada are suspected to have altered the predator–prey balance between American white pelican Pelecanus erythrorhynchos and Cui-ui Chasmistes cujus. We estimated the loss of the adult Cui-ui population to pelican predation over a 13-year period by netting and ...

Parasitic Helminths of the American White Pelican, Pelecanus erythrorhynchos, from Florida, U.S.A

Comparative Parasitology, 2004
Thirty-three species of helminths (22 trematodes, 3 cestodes, 7 nematodes, and 1 acanthocephalan) were recovered from 29 American white pelicans, Pelecanus erythrorhynchos, collected in Florida, U.S.A., between 1982 and 2001. The number of helminth species per infected bird ranged from 3 to 17 (x = 11).
