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...

Improved population estimates through the use of auxiliary information Improved population estimates through the use of auxiliary information
When estimating the size of a population of birds, the investigator may have, in addition to an estimator based on a statistical sample, information on one of several auxiliary variables, such as: (1) estimates of the population made on previous occasions, (2) measures of habitat variables associated with the size of the population, and (3) estimates of the population sizes of other...

The winter season - Northern Great Plains The winter season - Northern Great Plains
This winter was hardly a winter by usual standards. At Grand Forks six record highs were set in February, a month which averaged 11°F above normal, and a -20° reading was not recorded the entire season for the first time in 50 years. Fort Peck Lake in Montana finally iced over February 12, only to begin reopening three days later (CMC). Temperatures reached into the 70s in South Dakota...

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.
