Territorial behavior, pesticides, and the population ecology of red-shouldered hawks in central Maryland, 1943-1971 Territorial behavior, pesticides, and the population ecology of red-shouldered hawks in central Maryland, 1943-1971

Pen-reared fulvous tree ducks used in movement studies of wild populations Pen-reared fulvous tree ducks used in movement studies of wild populations
To obtain movement data on wild fulvous tree ducks (Dendrocygna bicolor) 165 immature pen-reared fulvous tree ducks were color-marked and released in three southeast Texas counties in July October 1969/70. Nine (5 percent) of the marked birds were recovered from 3 days to 9 months after release, and an additional 15 birds provided sight records. Many released birds apparently became...

Pesticide residues in birds and mammals Pesticide residues in birds and mammals
SUMMARY: Residues of organochlorine pesticides and their breakdown products are present in the tissues of essentially all wild birds throughout the world. These chemicals accumulate in fat from a relatively small environmental exposure. DDE and dieldrin are most prevalent. Others, such as heptachlor epoxide, chlordane, endrin, and benzene hexachloride also occur, the quantities and kinds
