Comparison of breaking strength and shell thickness as evaluators of white-faced ibis eggshell quality Comparison of breaking strength and shell thickness as evaluators of white-faced ibis eggshell quality
Data from a 1986 field study of white-faced ibis (Plegadis chihi) nesting at Carson Lake, Nevada, were used to compare the utility of eggshell strength measurement and eggshell thickness as indicators of eggshell quality. The ibis population had a history of reproductive failure correlated with elevated egg concentrations of p, p'-DDE, hereafter referred to as DDE. Eggs from 80 nests...

Taxonomic status of the coquette hummingbird of Guerrero, Mexico Taxonomic status of the coquette hummingbird of Guerrero, Mexico
An isolated population of small hummingbirds in the state of Guerrero, Mexico, was originally named as a subspecies (brachylopha) of the much more southerly Lophornis delattrei, the Rufous-crested Coquette (Moore 1949). The form was not reported again until rediscovered by Ornelas (1987) and remains known by only three male and two female specimens. Examination of two of the males...

[Book review] Ospreys: A natural and unnatural history [Book review] Ospreys: A natural and unnatural history
The Osprey (Pandion haliaetus) is now arguably the world's best known bird of prey. The DDT-related Osprey population crash in the northeastern United States resulted in an unparalleled amount of research during the last 20 years. In 1969, when I published my first paper on Ospreys in The Auk, there were only three or four osprey papers of consequence in the United States, plus an...

Toxicity of organic selenium in the diet to chinook salmon Toxicity of organic selenium in the diet to chinook salmon
The toxicity of two organoselenium diets was evaluated in 90- to 120-d partial life cycle tests with two life stages of chinook salmon (Oncorhynchus tshawytscha Walbaum). One of the diets contained fish meal made from high-selenium mosquitofish (Gambusia affinis Baird and Girard) collected from the selenium-laden San Luis Drain, California (here termed SLD diet) and the other contained...

The influence of social and endocrine factors on urine-marking by captive wolves (Canis lupus) The influence of social and endocrine factors on urine-marking by captive wolves (Canis lupus)
Although serum hormones varied seasonally in all adult animals, only dominant male and female wolves urine-marked. Serum testosterone and urine-marking rates, which increased during the fall/winter breeding season, were positively correlated in both male and female dominant wolves. Estradiol, which increased in conjunction with proestrus and estrus, was not correlated with female urine...

Organochlorines and selenium in California night-heron and egret eggs Organochlorines and selenium in California night-heron and egret eggs
Exceptionally high concentrations of DDE were found in black-crowned night-heron (Nycticorax nycticorax) (geometric mean 8.62 μg g−1 wet wt.) and great egret (Casmerodius albus) (24.0 μg g−1) eggs collected from the Imperial Valley (Salton Sea), California in 1985. DDE concentrations in 14 of the 87 (16%) randomly selected night-heron eggs from six colonies (two in San Francisco Bay...

Evaluation of three miniature radio transmitter attachment methods for small passerines Evaluation of three miniature radio transmitter attachment methods for small passerines
Thirty-two immature common yellowthroats were used to evaluate three methods of attaching radio transmitters to the backs of small passerines: adhesive, velcro, and harness. There were no significant differences between the three methods; however, the adhesive method of transmitter attachment to small birds was found to be the preferred technique.
