C.S. Robbins, D. Bystrak, P.H. Geissler
1986, Resource Publication 157
The Breeding Bird Survey (BBS) is an ongoing cooperative program sponsored jointly by the U.S. Fish and Wildife Service and the Canadian Wildlife Service.

Deer population in the Central Superior National Forest, 1967-1985
M.E. Nelson, L.D. Mech
1986, Research Paper NC-271
Deer were aerially censused each winter from 1976 through 1985 in a 400-sq km2 area near Isabella, Minnesota, in the Central Superior National Forest; a correction factor based on aerial observability of radio-tagged deer in the same region was then applied to the census figures. Deer numbers, which had reached...
Lethal Dietary Toxicities of Environmental Contaminants and Pesticides to Coturnix
E. F. Hill, M.B. Camardese
1986, Fish and Wildlife Technical Report No. 2
Five-day subacute dietary toxicity tests of 193 potential environmental contaminants, pesticides, organic solvents, and various adjuvants are presented for young coturnix (Japanese quail, Coturnix japonica Temminck and Schlegel). The report provides the most comprehensive data base available for avian subacute dietary toxicity tests and is primarily intended for use in...

1986, Book chapter, Raptor Conservation in the Next 50 Years
During the 50-year period 1931-80, 422,000 raptors were banded in the United States and Canada. Encounter rates were calculated, by decades of banding, for all birds reported outside of the l0-min block of latitude and longitude where they had been banded. Encounter rates for the various raptor species decreased from...
Use of miniroutes and Breeding Bird Survey data to estimate abundance
C.S. Robbins, B.A. Dowell
1986, Book chapter, Proceedings of the Second Northeastern Breeding Bird Atlas Conference
1. Information on relative abundance is easily obtained and adds greatly to the value of an atlas project. 2. The Breeding Bird Survey (BBS) provides annual counts (birds per 50 roadside stops) that can be used to: (1) map relative abundance by physiographic region within a state or province,...

Kesterton Reservoir is a series of ponds comprising 1,200 acres sitting in the grasslands of the Kesterton National Wildlife Refuge. It is bounded on the east by the San Luis Drain, a concrete-lined canal that discharges agricultural drainage into the ponds at their southern end, from which point it then...
Immunosuppressive effects of lead
J. Christian Franson
J.Scott Feierabend, A.Brooke Russell, editor(s)
1986, Book chapter, Lead poisoning in wild waterfowl - A workshop
Immunosuppressive effects of lead were reported as early as 1966, when it was noted that lead increased the sensitivity of rats to bacterial endotoxins (Selye et al. 1966). Since then a substantial body of literature has demonstrated adverse effects of lead on the immune system in a variety of laboratory...
