Status and trends of the Canada Goose Branta canadensis in France
An enquiry to determine the distribution and abundance of the Canada Goose Branta candensis in France was undertaken in 2008. Responses were received from 92 out of the 96 departments. Canada Geese were reported in 56 of the 92 departments, in 8 of which the species had only appeared after 2000.

Little is known about what happens to juvenile birds after one or both of their parents are harvested by hunters during the post‐fledging dependency period. Here, we compare the fate of juvenile Canada geese Branta canadensis that lost ≥ 1 parent to hunters (orphans) during this period to other juveniles that retained both parents (non‐orphans). For 25

Evaluation of the effects of september hunting seasons on Canada geese in Nebraska
Populations of temperate‐nesting Canada geese (Branta canadensis) have increased in Nebraska, USA, resulting in an increased number of nuisance and damage complaints.

Abstract Globally, bird and aircraft collisions are a major safety hazard and monetary expense for the aviation industry. Empirical evidence suggests that the behavioral response of an animal within close proximity of an approaching vehicle is a critical factor in determining whether a collision occurs.

Quantification of avian hazards to military aircraft and implications for wildlife management. [PDF]
Collisions between birds and military aircraft are common and can have catastrophic effects. Knowledge of relative wildlife hazards to aircraft (the likelihood of aircraft damage when a species is struck) is needed before estimating wildlife strike risk (

Assessing sustainable lethal take for great blue heron in the northeastern United States
We used Prescribed Take Level (PTL) models to estimate sustainable take limits for great blue heron and aid depredation permitting decisions by the USFWS in the northeastern United States. The PTL models suggested that current lethal take levels are sustainable and that cumulative authorized regional take should not exceed 2,650 individuals per year ...

Evidence of territoriality and species interactions from spatial point-pattern analyses of subarctic-nesting geese. [PDF]
Quantifying spatial patterns of bird nests and nest fate provides insights into processes influencing a species' distribution. At Cape Churchill, Manitoba, Canada, recent declines in breeding Eastern Prairie Population Canada geese (Branta canadensis ...

A theoretical model of flock formation to understand trade‐offs between cooperation and competition
Abstract Migratory birds often form flocks during spring migration and compete for territories once they arrive at breeding sites. Understanding the emergence and structure of these flocks has important implications for avian ecology and conservation, as flocking can influence migration success, resource distribution, and population resilience. In this
