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...

Captive and field-tested radio attachments for bald eagles Captive and field-tested radio attachments for bald eagles
The effects of two radio transmitter attachment techniques on captive and one attachment technique on wild Bald Eagles (Haliaeetus leucocephalus) were studied. A Y-attachment method with a 160-g dummy transmitter was less apt to cause tissue damage on captive birds than an X-attachment method, and loosely fit transmitters caused less damage than tightly fit transmitters Annual survival...

Colony differences in response to trapping in roseate terns Colony differences in response to trapping in roseate terns
Both members of seabird pairs are normally required to fledge young. Seabirds that nest in sites accessible to predators usually have one parent in attendance during the egg/chick phase. Time devoted to foraging can vary with individual skill and age, prey availability and abundance (Seamy 1978), and distance to foraging grounds (Safina 1990). Although average skill of similar-aged...

Organochlorine residues in bat guano from nine Mexican caves, 1991 Organochlorine residues in bat guano from nine Mexican caves, 1991
Samples of bat guano, primarily from Mexican free-tailed bats (Tadarida brasiliensis), were collected at nine bat roosts in caves in northern and eastern Mexico and analysed for organochlorine residues. DDE, the most abundant residue found in each cave, was highest (0.99 p.p.m. dry weight) at Ojuela Cave, Durango. Other studies of DDE in bat guano indicate that this concentration is too...

Can we manage for biological diversity in the absence of science? Can we manage for biological diversity in the absence of science?
Conservation of biological diversity is dependent on sound scientific information about underlying ecological processes. Current knowledge of the composition, distribution, abundance and life cycles of most species of plants and animals is incomplete, insufficient, unreliable, or nonexistent. Contemporary managers are also confronted with additional levels of complexity related to...

North American migratory bird management issues North American migratory bird management issues
As human population and industry have grown in North America, land-use practices have greatly altered the landscape. As a result of this changed landscape, several migratory bird populations have declined in recent years. For waterbirds, there have been several milestones: the 1986 North American Waterfowl Management Plan (NAWMP) and the 1989 North American Wetlands Conservation Act. As...

Point count length and detection of forest neotropical migrant birds Point count length and detection of forest neotropical migrant birds
Comparisons of bird abundances among years or among habitats assume that the rates at which birds are detected and counted are constant within species. We use point count data collected in forests of the Mid-Atlantic states to estimate detection probabilities for Neotropical migrant bird species as a function of count length. For some species, significant differences existed among years...
