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.

Logarithmic relationship of DDE residues to eggshell thinning
A concentration-effect relationship seems to exist between DDE in eggs and shell thinning. It seems to follow a mathematically similar pattern in different species though it seems to operate at different levels.

Some effects of aldrin-treated rice on Gulf Coast wildlife
Wildlife casualties from aldrin-dieldrin poisoning are associated with the planting of aldrin-treated rice seed along the Texas Gulf Coast. The fulvous tree duck (Dendrocygna bicolor), which depends on the rice field habitats and is highly susceptible to aldrin-dieldrin poisoning, is suffering a serious population decline in that area. Dead waterfowl, shorebirds, and passerines were collected on
