The Occurence of Ecological Traps in Bird Populations: Is our Knowledge Sufficient? A Review
Journal of Landscape Ecology, 2012 Anthropogenic changes in a landscape create new cues for birds, which must permanently adapt to these. If landscape changes occur too quickly, individuals have insufficient time to develop adequate reactions.

Studies on the Reproductive Performance of a Trap-Nested Flock of Pilgrim Geese
Poultry Science, 1956 Abstract INTRODUCTION THERE has been a renewed interest in recent years in Canada and the United States in the domestic goose as a meat bird, particularly as a meat bird that can obtain a large part of its food from pasture. Interest in the goose has also increased with the discovery that geese can be used very efficiently to control weeds in such ...

Radiomarking brood‐rearing mallard females: Implications for juvenile survival
Wildlife Society Bulletin, 2012 Radiotelemetry is frequently used to measure habitat use, movements, and survival in birds; presumably, outfitting adult females with radiotransmitters does not influence juvenile survival, but this critical assumption is rarely tested.

Zoologia (Curitiba), 2018 Identification of the predators of bird nests is essential to test ecological and evolutionary hypotheses and to make practical management decisions. A variety of nest monitoring devices have been proposed but many remain difficult to set up in the field.

Species diversity and community structure in trap-nesting bees in Southern Brazil [PDF]
Apidologie, 2005 Le but de cette etude etait de recenser la faune d'abeilles solitaires qui nidifie dans des cavites pre-existantes dans trois habitats differents du Parque Municipal das Araucarias (etat du Parana, Bresil). Les principales questions abordees dans cet article sont: la composition des especes d' abeilles varie-t-elle de facon significative entre les ...
