Acid-fast intranuclear inclusion bodies in the kidneys of mallards fed lead shot
Acid-fast intranuclear inclusion bodies were found in the cells of the proximal convoluted tubules of the kidneys of mallards fed one, two, three or eight number 6 lead shot and maintained on cracked or whole corn and on grain-duck pellet diets. No acid-fast inclusion bodies were found in mallards fed one or three lead shot but maintained on a duck pellet ration. Dietary factors may be responsible

Spermatogenesis in bald eagles experimentally fed a diet containing DDT
When Bald Eagles were fed DDT in the diet at the level of 10 ppm (dry weight basis) for periods of 60 and 120 days, there was no interference with spermatogenic activity. Degenerative testicular changes were produced only by levels of DDT that produced abnormal neurological signs and usually resulted in death. Histological examination of these testes indicates that Bald Eagles have a seasonal test

Production of young per nest in the 1930's compares favorably with the production of young in the populations examined in 1963. It is suggested, based on historical evidence, that a decline in the numbers of these birds h
