Investigating Tunisian artificial wetlands revealed a significant carrying capacity and refuge serving for the conservation of numerous wintering and endangered waterbird species of high nature conservation value, the White-headed Duck Oxyura leucocephala that has been observed with relatively high numbers representing more than 40% of the assessed Tunisian–Algerian population.

Randomness, Area, and Species Richness

Analysis of censuses of breeding birds on islands in Pymatuning Lake, a reservoir at the Pennsylvania-Ohio border, yields the conclusion that for these islands the variation of the number of resident avian species with island size is that which one would expect if the birds were distributed randomly.
Breeding Birds of Isolated Woodlots: Area and Habitat Relationships.
- Environmental ScienceEcology

Results from Illinois support previous conclusions that species that breed in forest interior habitat and winter in the tropics are most likely to be adversely affected by a reduction in forest habitat and show that bird communities in isolated tracts of forest are not random assemblages, but rather that species found in smaller woodlots are subsets ofspecies found in larger forests.

The distance of pintail nests from water was determined, and the hypothesis that male pursuit flights cause hens to nest far from water to avoid male-chasing was repudiated in favor of one that such behavior reduces nest predation.
