Subacute dietary toxicities of dicrotophos and dieldrin in time-replicated trials with young ring-necked pheasants and mallards Subacute dietary toxicities of dicrotophos and dieldrin in time-replicated trials with young ring-necked pheasants and mallards
The dietary toxicities of (E)-phosphoric acid 3-(dimethylamino)-1-methyl-3-oxo-1-propenyl dimethyl ester (dicrotophos) and 3,4,5,6,9,9-hexachloro-1a,2,2a,3,6,6a,7,7a-octahydro-2,7:3,6-dimethanonaphth[2,3-b]oxirene (dieldrin) to 10-day-old ring-necked pheasants (Phasianus colchicus) and 5-day-old mallards (Anas platyrhynchos) were compared in five time-replicated trials. Toxicities were...

Seasonal brain acetylcholinesterase activity in three species of shorebirds overwintering in Texas Seasonal brain acetylcholinesterase activity in three species of shorebirds overwintering in Texas
There was no seasonal variation in average brain AChE activity for the 3 species of wild birds collected between October and February. Further work needs to be done, however, covering an even broader time frame which includes the reproductive cycle. It appears that some birds feeding at the mouth of an agricultural drain, at some distance from the nearest pesticide applications, were...

Lead shot incidence in sediments and waterfowl gizzards from Merrymeeting Bay, Maine Lead shot incidence in sediments and waterfowl gizzards from Merrymeeting Bay, Maine
Lead shot in bottom sediments from Merrymeeting Bay, Maine, averaged 99,932 shot/ha. More shot (P 0.05) was present in silt sediments than in sand sediments. Number 6 size shot was the most abundant in all 6 river deltas sampled. Ingested lead shot occurred in gizzards of 6 of 10 waterfowl species. Lead shot occurred in 5.9-8.1% of the black ducks (Anas rubripes) sampled during the...

Techniques for trapping, aging, and banding wintering canvasbacks Techniques for trapping, aging, and banding wintering canvasbacks
Techniques used to trap, band, and determine age of Canvasbacks during winter on Chesapeake Bay are presented. Canvasbacks were captured with welded-wire traps baited with corn. Two trap designs were used and traps and trapping techniques are described. Ducks were dipnetted from traps and held in modified poultry crates that provided seclusion and ventilation and allowed birds to dry...

Estimating reproductive success in colonial waterbirds: An evaluation Estimating reproductive success in colonial waterbirds: An evaluation
To estimate reproductive success in a population one ideally would like to determine the number of young fledged per nesting female. However, this is difficult because often (1) the adults are not individually marked, (2) the colony is not visited daily, and (3) the investigator is unable to monitor all young until they fledge. If adults are unmarked and successful renesting occurs...

Inclusion body hepatitis in kestrels (Falco sparverius) Inclusion body hepatitis in kestrels (Falco sparverius)
Inclusion body disease of suspected adenovirus etiology was the apparent cause of death of 9 captive kestrels (Falco sparverius). Cloacal hemorrhage was the only prominent gross lesion; disseminated hepatocellular necrosis and intranuclear inclusion bodies were evident microscopically. Attempts to reproduce the disease, and to propagate and serologically characterize the agent were...

Organophosphate insecticide poisoning of Canada geese in the Texas panhandle Organophosphate insecticide poisoning of Canada geese in the Texas panhandle
Sixteen hundred waterfowl, mostly Canada Geese, died near Etter, Texas, in late January 1981 from anticholinesterase poisoning. Winter wheat in the area of the die-off had been treated with organophosphate insecticides to control greenbugs. Cholinesterase (ChE) levels in brains of a sample of geese found dead were 75% below normal, enough to account for death (Ludke et al. 1975). The

Hormonal responses and tolerance to cold of female quail following parathion ingestion Hormonal responses and tolerance to cold of female quail following parathion ingestion
Thirty-week-old female bobwhite quail (Colinus virginianus), maintained at 26 + 1?C, were provided diets containing 0,25, or 100 ppm parathion ad libitum. After 10 days, birds were exposed to mild cold (6 + 1?C) for 4,8, 12, 24, or 48 hr. Brain acetylcholinesterase activity was inhibited in a dose-dependent manner in birds receiving 25 and 100 ppm parathion. Body weight, egg production...
