Hawaiian birds
Hawaii's 132 islands, reefs, and shoals extend 1,523 miles from the southernmost island of Hawaii to the northernmost islands at Kure Atoll. The northernmost islands, now eroded almost to sea level, are about 27 million years old, whereas the still-forming island of Hawaii is only about 750,000 years old. The Hawaiian Islands are the most isolated in the world and, as such, have developed many spe

Recent changes in the ranges of North American birds
The North American Breeding Bird Survey has provided an annual index of population change since 1966. About 2400 randomly distributed roadside routes of 50 three-minute stops each provide the basic data for computer analysis. One of the reports produced shows the percentage of routes on which each species is encountered in each state and each Canadian province. This percentage is used to show expa

Seasonal Influence of Nutrients on the Physiology and Behavior of Captive Canvasbacks (Aythya valisineria)
Captive canvasbacks (Aythya valisineria) were maintained ad libitum on five diets during the winters of 1978-79 and 1979-80 to evaluate the effects of varying protein and energy levels on feed intake and condition. Diets were formulated to simulate either a natural diet high in invertebrates or one high in vegetation. Two diets low in protein and energy simulated stress diets. Feed intake durin

Upper Wisconsinan submarine end moraines off Cape Ann, Massachusetts
Seismic profiles across the southwest end of Jeffreys Ledge, a bathymetric high north of Cape Ann, Massachusetts, reveal two end moraines. The moraines overlie upper Wisconsinan glacialmarine silty clay and are composed mostly of subaqueous ice-contact deposits and outwash. They were formed below sea level in water depths of as much as 120 m during fluctuations of a calving ice front. The moraines
