Kirtland's warbler population holds near historic highs
|
In
July, Michigan Department of Natural Resources officials
announced Michigan's 2002 population of the endangered
Kirtland's warbler is only slightly lower than the 2001
survey.
Biologists,
researchers and volunteers counted 1,050 singing males
during the official 2002 census period, which was completed
in mid-June. This compares to last year's 1,085-a record
year for the warbler population. The lowest survey numbers
occurred in 1974 and 1987, when only 167 singing males
were found.
The
census, started in 1951, has been conducted annually
since 1971. The birds are counted by listening for their
songs. The songs can be heard over one-quarter mile
away and provide an accurate method to census the birds
with minimum disturbance. Since only the males sing,
the minimum breeding population size (males plus females)
is estimated as twice the number of singing males counted.
The
Kirtland's warbler nests have been found only in jack
pine stands located in northern Michigan. The warbler
is a ground nester, selecting stands of trees four to
20 years old, with live branches that extend to the
ground. Historically, these stands of young jack pine
were created by natural wildfires that frequently swept
through northern Michigan. Modern fire suppression programs
altered this natural process, reducing Kirtland's warbler
habitat.
