On territorial behavior and other factors influencing habitat distribution in birds
TLDR
In this article, the Dickcissel sex ratio is employed as an indirect index of suitability and a sex ratio index was found to be correlated positively with density, consistent with the hypothesis that territorial behavior in males of this species limits their density.Abstract:
This example is provided so that non-theorists may see actual applications of the theory previously described. The Dickcissel sex ratio is employed as an indirect index of suitability. A sex ratio index was found to be correlated positively with density. This is consistent with the hypothesis that territorial behavior in the males of this species limits their density. This study provides a valid example of how the problem can be approached and offers a first step in the eventual identification of the role of territorial behavior in the habitat distribution of a common species.read more

Adaptive selection of foraging and nesting habitat by black kites (Milvus migrans) and its implications for conservation: a multi-scale approach
TL;DR: In this article, the authors investigate selection of foraging and breeding habitat in a high-priority population in the Italian pre-Alps and find that black kites foraged preferentially near water, over extensively managed grassland and within 1 km of nest-sites.

TL;DR: It is concluded that behavioural diversification in habitat use and activity reduces intraspecific competition in preferred littoral habitats, which may facilitate the emergence of an ideal free distribution of pike along resource gradients.

TL;DR: This study indicates that risk-taking behavior is state dependent and changes temporarily to compensate for a period of food restriction, resulting in compensatory growth and a recovery of the weight loss caused by dietary restriction.

Animal dispersion in relation to social behaviour
TL;DR: Wynne-Edwards has written this interesting and important book as a sequel to his earlier (1962) Animal Dispersion in Relation to Social Behaviour, and reviewing it has proven to be a valuable task for one who normally is only at the periphery of the group selection controversy.
