Procedures for the use of aircraft in wildlife biotelemetry studies Procedures for the use of aircraft in wildlife biotelemetry studies
This is a report on the state of the art methodology and on questions that arise while one is preparing to use aircraft in a biotelemetry study. In general the first step in preparing to mount an antenna on an aircraft is to consult with a certified aircraft mechanic. Aircraft certification is discussed to provide background information concerning the role of the Federal Aviation...

Use of 35-mm color aerial photography to acquire mallard sex ratio data Use of 35-mm color aerial photography to acquire mallard sex ratio data
A conventional 35-mm camera equipped with an f2.8 135-mm lens and ASA 64 color film was used to acquire sex ratio data on mallards (Anas platyrhynchos) wintering in the Platte River Valley of south-central Nebraska. Prelight focusing for a distance of 30.5 metres and setting of shutter speed at 1/2000 of a second eliminated focusing and reduced image motion problems and resulted in high...

Key to trematodes reported in waterfowl Key to trematodes reported in waterfowl
This key is the second in a series for identification of the helminths reported in waterfowl (Family Anatidae, Order Anseriformes). The first was a key to nematodes (McDonald 1974). The trematodes show the greatest variety of forms among the helminth parasites of waterfowl, including over half of all species reported; sometimes this group also includes the greatest part of the worms in a...

Observations on black-crowned night heron breeding success in a North Dakota marsh Observations on black-crowned night heron breeding success in a North Dakota marsh
Storms and mammalian predation severely reduced production in a Black-crowned Night Heron (Nycticorax nycticorax) colony in two years and drought prevented nesting in two other years from 1976 to 1980. Maximum estimated production was 2.2 young per pair in 1978, the only year production was sufficient to maintain the population.

Birds of the St. Croix River valley: Minnesota and Wisconsin Birds of the St. Croix River valley: Minnesota and Wisconsin
The St. Croix River Valley encompasses nearly 11,550 km2 in east-central Minnesota and northwestern Wisconsin. A wide range of habitats are available for birds including upland oak, lowland deciduous, maple-basswood, lowland and upland coniferous forests, natural basin wetlands, and grasslands. Situated in the north-central region of the United States, the valley is a biological...

The role of nutrient reserves in mallard reproduction The role of nutrient reserves in mallard reproduction
Mallard (Anas platyrhynchos) populations breeding in temperate North America obtain a significant part of the energy and lipid requirements of reproduction at sites occupied prior to arrival on the breeding grounds. Protein for egg formation, however, is obtained principally from the diet during the nesting period. Both sexes arrive heavy and fat in North Dakota but experience...
