estimated 4 to 10+ million night migrating birds collide with
communication towers each year.
Suspected Collision Risk Factors:
U. S. Fish
and Wildlife Service (USFWS) Action
the number of communication towers increase rapidly, the Service
is focusing more attention on the bird collision issue and has
considered action under the Migratory Bird Treaty Act.
a proactive means of addressing the issue, the USFWS established
the Communication Tower Working Group (CTWG), a consortium of
federal agencies, the communication industry, environmental organizations,
private consulting firms, and other stakeholders.
Current efforts include identifying the issue and establish research
strategies that will quantify risk factors and lead to reduction
of mortality. The USFWS now has voluntary siting and technical
guidelines for communication towers and wind turbines.
Kerlinger serves as a member of the Communication Tower Working
Group and sits on the CTWG Research Subcommittee.
& Kerlinger, LLC, under contract with the USFWS, reviewed
the recent literature on the tower collisions. That
report is available on the USFWS website.
& Kerlinger are now working with several corporations to reduce
bird fatalities at communication tower sites.
