Will the availability of insular nesting sites limit reproduction in urban Canada goose populations?
Article Abstract:
The nesting success of geese in urban areas in Canada was investigated. Data from an 11-year study were analyzed to compare nesting success of geese found on the islands to those on the mainland. Results showed that nest success was similar for geese nesting on both islands and the mainland. In addition, island nesters had larger clutches than mainland nesters. It was also found that there was no difference between island nesters and mainland nesters when it comes to age, mass or prior breeding experience. These findings suggest that availability of insular nesting sites may not play a crucial role in limiting reproduction of urban Canada goose populations.

Effectiveness of volatile irritants at reducing consumption of eggs by captive coyotes
Article Abstract:
Recruitment rates of ground-nesting birds can be seriously reduced by mammalian predators. A new study of coyotes investigates the hypothesis that predators can be taught to avoid eggs by prior exposure to foods injected with an illness-producing chemical. Findings suggest that coyotes will avoid eating food associated with specific chemicals although the same food is consumed when the association is removed. Chemicals with the most deterrent potential are cinnamaldehyde and pulegone.

Will the availability of insular nesting sites limit reproduction in urban Canada goose populations?
Article Abstract:
Research using data from southern New England has compared nesting success of Canada geese nesting on islands with that of geese nesting on the mainland. No difference was found in nest success between island nests and mainland nests, and there was no difference in female age or mass between island nesters and mainland nesters. The results of this research do not support the view that only young and inexperienced Canada geese choose mainland nest sites.
