Atlantic Flyway review: Region V Atlantic Flyway review: Region V
Banding activities in Region V in 1975 were similar to those of 1974. The stations at Woodend and St. Michaels were discontinued, but a new station 5 miles south of St. Michaels was opened at Bellevue by Henry Armistead. For the locations of the various banding stations in Region V see the map in the 1974 report (North American Bird Bander 1:75-82). As in the past several years, the...

Conventional atlases are in progress in the states of Maryland (2.5 km)

DDE increased the toxicity of parathion to coturnix quail DDE increased the toxicity of parathion to coturnix quail

Pretreatment with 5 or 50 ppm DDE in the diet for 12 weeks resulted in increased cholinesterase (ChE) activity in plasma, but not in the brain. Dietary concentrations of 5 and 50 ppm DDE caused increased susceptibility of quail that were challenged...

Research, management, and status of the osprey in North America Research, management, and status of the osprey in North America

Researchers used banding, localized studies, aerial surveys, and pesticide analyses to identify factors influencing regional populations. Declining populations showed extremely poor production, contamination...
