The role of the white-eyed vireo in the dispersal of Bursera fruit on the Yucatan Peninsula The role of the white-eyed vireo in the dispersal of Bursera fruit on the Yucatan Peninsula
White-eyed vireos (Vireo griseus) winter in the forests and secondary growth of the Yucatan Peninsula where Bursera simaruba (Burseraceae) is an abundant tree. Twenty-five per cent of all white-eyed vireos observed foraging visited Bursera trees. In addition, presence and abundance of territorial white-eyed vireos in small forest patches were correlated with the size of the Bursera crop...

DNA fingerprint similarity between female and juvenile brown-headed cowbirds trapped together DNA fingerprint similarity between female and juvenile brown-headed cowbirds trapped together
This DNA fingerprinting study investigates whether females of the brood parasite brown-headed cowbird, Molothrus ater, associate with their own juvenile offspring at feeding sites more often than would be expected by chance. Cowbirds lay their eggs in the nests of a variety of host species and, as far as is known, leave them to the care of foster parents. Using baited walk-in funnel...

Inter-relation of cytochrome P450 and contaminants burdens in sibling heron embryos and nestlings Inter-relation of cytochrome P450 and contaminants burdens in sibling heron embryos and nestlings
Hepatic cytochrome P450-associated monooxygenase activities were measured in 11-day-old nestling black-crowned night-herons (Nycticorax nycticorax) collected from a reference site (next to the Chincoteague National Wildlife Refuge, Virginia) and three polluted sites (Cat Island, Green Bay, Lake Michigan, Wisconsin; Bair Island, San Francisco Bay, California; West Marin Island, San...

Mississippi sandhill cranes Mississippi sandhill cranes
Resident sandhill cranes formed a continuous population in Georgia and Florida and widely separated populations along the Gulf Coastal Plain of Texas, Louisiana, Mississippi, and Alabama (Figure). The Mississippi sandhill crane (Grus canadensis pulla) was one of the widely separated populations on the Coastal Plain that bred in pine savannas in southeastern Mississippi, just east of the...

Comments on the status of revived old names for some North American birds Comments on the status of revived old names for some North American birds
We discuss 44 instances of the use of generic, specific, or subspecific names that differ from those generally in use for North American (sensu AOU 1957) birds. These names are generally older than the names presently used and have been revived on the basis of priority. We examine the basis for the proposed changes and make recommendations as to which names should properly be used in an...

Managing North American waterfowl in the face of uncertainty Managing North American waterfowl in the face of uncertainty
Informed management of waterfowl (or any animal population) requires management goals and objectives, the ability to implement management actions, periodic information about population and goal-related varlables, and knowledge of effects of management actions on population and goal-related variables. In North America, international treaties mandate a primary objective of protecting...

Comparison of birds detected from roadside and off-road point counts in the Shenandoah National Park Comparison of birds detected from roadside and off-road point counts in the Shenandoah National Park
Roadside point counts are generally used for large surveys to increase the number of samples. We examined differences in species detected from roadside versus off-road (200-m and 400-ha) point counts in the Shenandoah National Park. We also compared the list of species detected in the first 3 minutes to those detected in 10 minutes for potential species biases. Results from 81 paired...

Geographic patterns in relative abundances and population trends of breeding and wintering loggerhead shrikes in North America Geographic patterns in relative abundances and population trends of breeding and wintering loggerhead shrikes in North America
In North America, the Breeding Bird Survey and the Christmas Bird Count provide data that are collected at sites visited each year, and the site-specific data can be placed in a Geographic Information System and smoothed to produce contour maps of relative abundance and trend for the United States and southern Canada. We develop these contour maps for Loggerhead Shrike (Lanius...
