Population trends of woodland birds from the North American Breeding Bird Survey Population trends of woodland birds from the North American Breeding Bird Survey

Population trends of woodland birds were summarized from BBS data over 1966-1991, 1966-1979, and 1982-1991. For the entire woodland bird assemblage, increasing species outnumbered decreasing species in all regions except central North America during 1966-1991. However, the proportion of decreasing species increased in most regions during the 19821991 interval. This population trend was...

Falcon versus grouse: flight adaptations of a predator and its prey Falcon versus grouse: flight adaptations of a predator and its prey

Several falcons were trained to fly along a 500 m course to a lure. The air speeds of the more consistent performers averaged about 1.5 times their calculated minimum power speeds, and occasionally reached 2.1 times the minimum power speed. Wing beat frequencies of all the falcons were above those estimated from earlier field observations, and the same was true of wild Sage Grouse...

Prevalence of eustrongylidosis in wading birds from colonies in California, Texas, and Rhode Island, USA Prevalence of eustrongylidosis in wading birds from colonies in California, Texas, and Rhode Island, USA

Snowy Egret (Egretta thula) and Black-crowned Night-Heron (Nycticorax nycticorax) nestlings from colonies in Texas, Rhode Island, and California and Great Egret (Casmerodius albus) nestlings from Texas were examined for eustrongylidosis, or infection by the parasitic nematode Eustrongylides spp. In 31% (24/77) of all broods examined, at least one nestling was infected. Snowy Egret broods...
