Canvasback ducks Canvasback ducks
Canvasbacks (Aythya valisineria) are unique to North America and are one of our most widely recognized waterfowl species. Unlike other ducks that nest and feed in uplands, diving ducks such as canvasbacks are totally dependent on aquatic habitats throughout their life cycle. Canvasbacks nest in prairie, parkland, subarctic, and Great Basin wetlands; stage during spring and fall on...

Mark-resighting analysis of a California gull population Mark-resighting analysis of a California gull population
California gulls (Larus californicus) of known age and sex were censused on their breeding colony in 1979, 1980 and 1984 through 1993. Ages of 235 males and 196 females ranged from 4 to 27 years. Age classes used in the analysis were limited to 17, 4 through 19, and 20 or more as a final age category because data on gulls over 20 were sparse. Survival declined with age in a way that was

Mycotoxin-induced disease in captive whooping cranes (Grus americana) and sandhill cranes (Grus canadensis) Mycotoxin-induced disease in captive whooping cranes (Grus americana) and sandhill cranes (Grus canadensis)
In 1987, an epizootic in cranes at the Patuxent Wildlife Research Center, Laurel, Maryland, USA, caused illness in 80% of 300 captive whooping cranes (Grus americana) and sandhill cranes (Grus canadensis) and death of 15 of these cranes. Gross pathology findings were inconclusive and consisted of dehydration, atrophy of fat, renal insufficiency, and small spleens. Extensive testing...

Successful nesting behavior of Puerto Rican parrots Successful nesting behavior of Puerto Rican parrots
We analyzed nesting behavior of five pairs of the endangered Puerto Rican Parrot (Amazona vittata) during eight successful nesting attempts. Each stage of the nesting cycle (egg laying, incubation, early chick rearing, and late chick rearing) was characterized by distinct trends or levels of behavior. During egg laying, female attentiveness to tile nest increased, and male attentiveness...

Evidence from tooth surface morphology for a posterior maxillary origin of the proteroglyph fang Evidence from tooth surface morphology for a posterior maxillary origin of the proteroglyph fang
Although the front-fanged venom delivery system of the Elapidae is believed to be derived from an aglyphous or opisthoglyphous colubroid ancestor, opinion is divided as to the end of the maxilla on which the proteroglyph fang originated. This study was undertaken to determine whether the evolutionary precursor of the proteroglyph fang was (a) a grooved posterior fang which migrated...

Breeding bird survey: Population trends 1966-92 Breeding bird survey: Population trends 1966-92
The North American Breeding Bird Survey (BBS) was begun in 1966 to collect standardized data on bird populations along more than 3,400 survey routes across the continental United States and southern Canada. The BBS has been used to document distributions and establish continental, regional, and local population trends for more than 250 species. We summarize here survey-wide patterns in...
