The following is from a e-newsletter sent out by Wild Ones, an organization
of natural landscapers that is based in Wisconsin. Although this is directed
to people in the United States, I thought some of the information might be
of interest to members of this list:

The U.S. Fish & Wildlife Service estimates the number of migratory birds

killed by collisions with communication towers to be between 4 million and
50

million per year. At least 96,000 towers are registered with the Federal

Communications Commission nationwide, and more are built every year. The FCC
is

seeking comments on the possible adoption of measures that would reduce
migratory

bird kills at communication towers. After many years of pressure from the
bird

conservation community, this is the first opportunity for public input.
Comments are

due by Jan. 22, 2007.

Communication towers have long been known, especially in Wisconsin, to be a
hazard

to birds, as the longest study to date was conducted here by Dr. Charles
Kemper: A

Study of Bird Mortality at a West Central Wisconsin TV Tower from 1957-1995.
Over

the 38-year period of the study, he collected 121,560 birds representing 123

species. On one night in 1963, he collected more than 12,000 birds, the
largest

single-night kill yet documented.

The number of birds killed by communications towers varies based on the type
of

lighting (medium intensity white strobe lights appears to be much better
than red

obstruction lighting systems), the use of guy wires (free-standing towers
are

better), tower height, and location of the tower. Communication devices
should be

collocated (all on one tower) whenever possible; and Environmental
Assessments

(EAs), prepared pursuant to the National Environmental Policy Act, should be

required for proposed facilities that could have adverse effects on
migratory birds.

EAs would be of particular importance for any places where there could be

cumulative impacts, such as known migratory pathways. A prime example is
along the

Gulf Coast, where birds make landfall after a lengthy and arduous migration.


FCC is seeking all comments, but prefers information based on the scientific
or

technical evidence. All comments need to include the agency name and be
identified

by WT Docket No. 03-187, FCC 06-164. To submit your comments, choose one of
the

following options. Go to http://www.regulations.gov or to

http://www.fcc.gov/cgb/ecfs/ (this is also the website to access the docket
and read

background documents) or e-mail ecfs@fcc.gov and include "get form" in the
subject

of the e-mail to receive a sample form to fill in or send via U.S. mail to
Federal

Communications Commission, 445 12th Street, SW., Washington, DC 20554.

Good background resources can be found at www.towerkill.com and at

www.fws.gov/migratorybirds/issues/towers/comtow.html or you can read the
entire

proposal on the Federal Register at
