LANSING, MI - The
population of the Kirtland’s
warbler – a bird that breeds in northern Michigan – continues to
bounce back.
The Michigan Department
of Natural Resources said last week a recently released annual survey shows the
bird’s population is at a record high.
Researchers and
volunteers in Michigan counted 2,063 singing males during the official 2012
survey period – up from 1,805 males a year ago. That’s the largest single-year
increase since 2007.
The lowest numbers were
documented in both 1974 and 1987, when 167 singing males were found.
Only males sing. The DNR
figures that each male has a mate with him, so the breeding population is
generally considered to be twice the count of the singing males.
Michigan has made
special preservation efforts to help the warbler, which is considered
endangered.
