Height distribution of birds recorded by collisions with civil aircraft

Article Abstract:

Aircraft collisions with birds in the United States due to increasing populations of large bird species cause serious economic and safety connected problems. An anlaysis of bird strike reports for civil aircraft in the US undertaken to determine the distribution of strikes by height above ground level (AGL) in relation to season of year and time of day revealed that efforts to reduce strikes should concentrate on the airport environment.

Evaluation of shifts in White-Tailed deer winter yards in the Adirondack region of New York

Article Abstract:

A study was undertaken in the Adirondack region of New York to determine the changes that have taken place during winter due to urban development relevant to the movement of white-tailed deer. Results showed that areas relatively low in density of development attracted the deer due to abundant presence of natural habitat and open areas.

Lethal control of red-winged blackbirds to manage damage to sunflower: an economic evaluation

Article Abstract:

Research indicates that lethal culling of red-winged blackbird populations via spring baiting would produce negligible benefits to sunflower growers, due to the variability of culling success and direct and indirect costs.
