Osprey distribution, abundance, and status in western North America: III. The Baja California and Gulf of California population Osprey distribution, abundance, and status in western North America: III. The Baja California and Gulf of California population
An estimated 810 ± 55 pairs (minimum estimate) of ospreys (Pandion haliaetus) were nesting in the study area during our survey (24 March-1 April 1977). Approximately 174 pairs nested along the Pacific side of Baja California, 255 pairs along the gulf side, 187 pairs on the Midriff Islands, and 194 pairs in coastal Sonora and Sinaloa. Most nested on cliffs adjacent to the sea (59%); some...

Delta-aminolevulinic acid dehydratase enzyme activity in blood, brain, and liver of lead-dosed ducks Delta-aminolevulinic acid dehydratase enzyme activity in blood, brain, and liver of lead-dosed ducks
Mallard ducks were dosed with a single shotgun pellet (ca. 200 mg lead). After 1 month there was about 1 ppm lead in blood, 2.5 in liver, and 0.5 in brain. Lead-induced inhibition of delta-aminolevulinic acid dehydratase enzyme in blood and cerebellum was much greater than in cerebral hemisphere or liver and was strongly correlated with the lead concentration in these tissues. The...

No. 2 fuel oil decreases embryonic survival of great black-backed gulls No. 2 fuel oil decreases embryonic survival of great black-backed gulls
The great black-backed gull (Larus marinus) is widespread in the northern hemisphere, breeding south to Britain and Ireland on the European side of the Atlantic and to Long Island in the United States where populations have increased markedly during the last 50 years (DRURY 1979). With growing exploitation of oil resources, seabird populations are being increasingly threatened by...

Organochlorine residues in six species of estuarine birds, South Carolina, 1971-75 Organochlorine residues in six species of estuarine birds, South Carolina, 1971-75
In South Carolina between 1971 and 1975, authors evaluated the occurrence of organochlorine residues in the laughing gull (Larus atricilla), white ibis (Eudocimus albus), glossy ibis (Plegadis falcinellus), American oystercatcher (Haematopus palliatus), willet (Catoptrophorus semipalmatus), and ruddy turnstone (Arenaria interpres). Tissues of birds found dead and eggs were analyzed...

Seasonal occurrence and distribution of submerged aquatic macrophytes in the tidal Potomac River Seasonal occurrence and distribution of submerged aquatic macrophytes in the tidal Potomac River
A systematic survey was conducted in the Tidal Potomac River in 1978 to determine the presence, abundance, and phenology of submersed aquatic macrophytes. The survey covered 81.5 km of main river and 59.3 km of tributary on the Maryland shore. Four regions were selected for the study: (1) Piscataway - Mattawoman Creek region (fresh-tidal river), (2) Nanjemoy Creek-Port Tobacco River...
