Monitoring Avian

Many of the long-term
monitoring programs for breeding landbirds indicate
declining population trends in migrant species in
eastern North America. While many trends have been
downward, the only long term program providing a measure
of productivity and estimates of survival is the
Monitoring Avian Productivity and Survivorship (MAPS)
program. The Observatory initiated one of Ohio’s first
MAPS sites in 1992 at the Navarre station. Other sites
have been added in Sandusky County, Blue Heron Reserve
in 1994, and Bowles Woods, Hamilton County in 1998.
MAPS’ objective is to document continental tendencies in
productivity and survivorship. The purpose of BSBO’s
breeding bird surveys is to not only meet national
objectives of MAPS but to address state and/or local
questions.
An important part of understanding population trends is
determining reproduction success for target species.
Utilizing the methodology developed by the Institute of
Bird Populations, constant effort mist netting allows
for comparison from site to site and year to year.
Standardization from year to year and continuation of
the study for at least twenty consecutive years at each
station are necessary in order to provide reliable
estimates of annual variations in productivity and
survivorship.
Banding operations are conducted once each ten day
period during June through early August. This time frame
reduces the confusion with major migration periods,
reduces trap biases from net familiarity, and reduces
capture interference on breeding success. These
long-term projects allow BSBO to investigate habitat
changes or succession and their effects on birds, avian
community changes, abundance, diversity, and species
richness over time in a variety of areas of Ohio.
