Molt patterns and weight changes of the American woodcock Molt patterns and weight changes of the American woodcock
A study of molt and changes in body weight of American Woodcock was conducted to better understand the summer and fall behavior of these birds and to indicate periods of physiological stress. The postnuptial molt of adults was a complete molt beginning in late June and ending by the middle of October. In contrast, the postjuvenal molt was a less intensive partial molt beginning in mid...

Distribution of two western clapper rail races as determined by responses to taped calls Distribution of two western clapper rail races as determined by responses to taped calls
During 1969 and 1970, surveys of the endangered Yuma Clapper Rail were conducted using taped calls to elicit responses from the birds. During the two summers, more than 158 Yuma clappers were located in cattailtule marshes along the Colorado River south of Needles, California, to the International Boundary, a distance of about 240 miles. Clappers (probably of the same race) were also...

Serotypes in Saccharomyces telluris: Their relation to source of isolation Serotypes in Saccharomyces telluris: Their relation to source of isolation
Three serotypes have been characterized with three reference strains of Saccharomyces telluris and designated as A, B, and C. One reference strain of Torpulopsis bovina, the imperfect form of S. telluris, belonged to serotype B. Strains (141) of S. telluris isolated from four columbid species were serotyped. All 98 strains of this yeast isolated from Columba livia (feral pigeon) belonged...

DDE effects on reproduction of ring doves DDE effects on reproduction of ring doves
Reproductive performance was measured for 126 days in twelve pairs of ring doves (Streptopelia risoria) fed a diet containing 40 ppm of p,p'-DDE and in twelve other pairs given untreated food. The DDE-treated doves took an average of 2 1/2 times longer to renest than controls, produced 13·5% fewer eggs/clutch, had 10% thinner eggs, and experienced twice as great mortality of young; all...

Proceedings of the Black-footed Ferret & Prairie Dog Workshop, September 4-6, 1973 Proceedings of the Black-footed Ferret & Prairie Dog Workshop, September 4-6, 1973
Both State and Federal agencies have been working with the black-footed ferret and prairie dog during the past few years. Much of the work is not extensive enough for publication in scientific journals and is, therefore, not reported. The objective of this Workshop was to bring workers together for discussion of the current status of the two species. Each of the Conservation Departments...

Wolf numbers in the Superior National Forest of Minnesota Wolf numbers in the Superior National Forest of Minnesota
Seventy-seven radio-tagged wolves (Canis lupus), including members of 12 adjacent packs, were located more than 3000 times, and observed on 1337 occasions, from 1968 through mid-1973. Projected population estimates for the 4203 square-mile Forest were 405 plus or minus 20 for winter 1971-72, and 388 plus or minus 14 for winter 1972-73.
