The North American Breeding Bird Survey The North American Breeding Bird Survey
A brief history of the North American Breeding Bird Survey (BBS) and a discussion of the technique are presented. The approximately 2000 random roadside routes conducted yearly during the breeding season throughout North America produce an enormous bank of data on distribution and abundance of breeding birds with great potential use. Data on about one million total birds of 500 species...

Bird activity levels related to weather Bird activity levels related to weather
The Breeding Bird Survey data bank serves as a primary source for studying effects of sky cover, wind speed, and temperature on bird census results. Other standardized methods, such as spot-mapping (Breeding Bird Census), point counts, banding, and the Winter Bird Survey, provide additional, but limited, means of assessing effects of weather. Numbers of songbirds detected are generally...

Olfactory pedunculotomy induced anosmia in the wolf (Canis lupus) Olfactory pedunculotomy induced anosmia in the wolf (Canis lupus)
A procedure for the surgical induction of anosmia in the wolf is described. Six wolves (4 altered and 2 sham) and one mongrel dog were operated; four wolves and the dog were bilaterally pedunculotomized, and two wolves were sham operated. Behavioral tests with the wolves confirmed that they were anosmic, and anatomical verification in the dog showed that the olfactory peduncle...

Effects of abundant species on the ability of observers to make accurate counts of birds Effects of abundant species on the ability of observers to make accurate counts of birds
Bird numbers can be estimated using a variety of methods (Emlen 1971, Berthold 1976, Reynolds et al. 1980). The number of birds counted is frequently reported in relation to some measure of effort: e.g. per unit area, per count period, per observer day, or per km of trail. The numbers recorded are sometimes those of only a single species (Kepler and Kepler 1973, Mayfield 1973, Van Riper...

Sampling strategies for radio-tracking coyotes Sampling strategies for radio-tracking coyotes
Ten coyotes radio-tracked for 24 h periods were most active at night and moved little during daylight hours. Home-range size determined from radio-locations of 3 adult coyotes increased with the number of locations until an asymptote was reached at about 35-40 independent day locations or 3 6 nights of hourly radio-locations. Activity of the coyote did not affect the asymptotic nature of...

Parental development of Eimerian coccidia in sandhill and whooping cranes Parental development of Eimerian coccidia in sandhill and whooping cranes
In contrast with isosporoid species of coccidia that have established extraintestinal phases of development, the eimeriids, except for a few species, generally have been considered inhabitants of the intestinal tract. Eimeria infection in sandhill cranes (Grus canadensis) and whooping cranes (G. americana) may result in disseminated visceral coccidiosis. Nodules were observed in the oral...
