Pesticidal residues in animal tissues
Tests with penned starlings, rats, pheasants, and ducks indicated that each species differs in sensitivity to the various pesticides. Residues in tissues are proportional to the degree of exposure during area treatment and they are also found in animals shot six or more months after treatment. The presence of more than 20-30 ppm of DDT, 20 ppm of chlordan, and 6-20 ppm of heptachlor epoxide in qua

Mallard age and sex determination from wings
This paper describes characters on the wing plumage of the mallard that indicate age and sex. A key outlines a logical order in which to check age and sex characters on wings. This method was tested and found to be more than 95 percent reliable, although it was found that considerable practice and training with known-age specimens was required to achieve this level of accuracy....The implications

Case report: Pox in the mourning dove in Maryland
Although trichomoniasis has received attention as a cause of death among mourning doves (Zenaidura macroura), ittle work has been done on other diseases of this species. Kossack and Hanson2 reported the occurrence of pox lesions in mourning doves in Illinois. Rosen3 reported that "pigeon pox" had caused a severe mortality in a mourning dove flock near Yreka, Siskiyou County, California. A severe
