Pesticide mortality of young white-faced ibis in Texas
The combination of the symptoms observed in sick and dying birds and the high brain residues in the three birds collected dying, as well as in two of the four collected dead, implicate dieldrin as at least one of the causes of mortality of young ibis at the Lavaca Bay colony. Mercury residues in the kidneys of all four dead young, including those with low brain residues of dieldrin, suggest that b

Effect of Hygromycin-B on pigeons (Columba livia) with and without Trichomonas gallinae
Hygromycin-B was administered in varied quantities to pigeons harboring nonvirulent Trichomonas gallinae and to pigeons free of T. gallinae. Both groups responded identically with large yellow caseous lesions in the upper digestive tract which superficially resembled canker (trichomoniasis). No mycotic association with the lesions could be established in either .group from sections stained with

Some physiologic blood values of wild diving ducks
Blood samples were obtained from 54 canvasbacks (Aythya valisineria), 30 lesser scaup (A. affinis), 3 ring-necks (A. collaris), and 3 buffleheads (Bucephala albeola), which were wintering on Chesapeake Bay. These blood samples were used for: red blood cell counts (cans. 2.56 x 106/mm3; scaup 2.45 x 106/mm3; ring-necks 2.50 x 106mm3; buffiehead 2.64 x lO6/mm3), packed cell volume (cans. 52.2%; sca

Immunologic status of mourning doves following an epizootic of trichomoniasis
An epizootic of trichomoniasis in mourning doves at the Carolina Sandhills National Wildlife Refuge began in 1969 and continued into 1970. The disease was seen in 16% of the adults and 2% of the immatures in 1970, but only one immature bird out of 37 surveyed (3%) carried Trichomonas gallinae. Challenge infection of 33 doves from the epizootic area showed 85 percent to be resistant to trichomoni

Egg measurements for three endangered species
From 1967 through 1969, external dimensions of the eggs of three endangered species of birds were measured. Included were 33 eggs of the Whooping Crane (Grus americana), 158 eggs of the Aleutian Canada Goose (Branta canadensis leucopareia), and 809 eggs of the Masked Bobwhite Quail (Colinus virginiana ridgwayi). In the literature, there are only scattered reports of small samples of Masked Bobwhit

A repellent for protecting corn seed from blackbirds and crows
Methiocarb [4-(methylthio)-3,-5-xylyl N-methylcarbamate] was tested as a seed treatment for repelling blackbirds and crows (Corvus sp.) from sprouting corn in South Carolina. The test was conducted on eight fields within a 0.25-square-mile area. Marked repellency occurred; sprout damage averaged 44 percent in the control fields and 0.3 percent in the fields treated with methiocarb.
