Cocobolo's New MoSI Banding Station

MoSI: Monitoreo de Sobrevivencia Invernal (Monitoring the Winter Survival of Neotropical Migratory Species)

Marvelwood is probably the first high school in North America to help establish and run a MoSI station in Latin America. Working with scientists from CREA as well as local students and adults from the community of LaZahina, Marvelwood Students helped map CREA's new MoSI station in the Cocobolo Nature Reserve during there visit this year. Between February 3rd through February 5th students were in the field from sunrise to sunset monitoring nets and processing both resident and migratory birds. During the banding period we captured 154 new birds, representing 61 different species.

This year the new MoSI station will only be able to operate two pulses (a pulse consists of three days of consecutive banding spaced at least three weeks apart throughout the wintering season) due to the heavy rains and mudslides in November and December. The roads leading to Cocobolo were not cleared until mid-January and new roads to the station had to be created. Next year the station will be able to operate the standard three or four pulses.

What is the MoSI program?

"About half of the bird species that breed in the temperate forests of North America over-winter in the northern Neotropics. Although these species spend more than half the year on their tropical wintering grounds, little is known about their habitat needs while there. IBP and partners across the northern Neotropics initiated the MoSI program in the winter of 2002-03 to begin to provide information on the habitat needs of migrant birds in the tropics. Through winter 2008-09, more than 60 cooperators have contributed data from > 140 stations to the program. These stations have been operated in 14 countries stretching from Mexico to Colombia (see figure below).

Distribution of banding stations that have registered with the MoSI program as of winter 2009-10.

MoSI Program Goals

MoSI is designed to address monitoring, research, and management goals.

The monitoring goal of MoSI is to provide estimates of overwintering apparent survival rates, annual apparent survival rates, and indices of physical condition for a suite of 25 landbird species in a variety of habitats and geographic regions.

Research goals of MoSI include (1) relating survival and physical condition to habitat, weather, and climate variables, (2) linking winter and breeding (from MAPS) population parameters, and (3) developing predictive population models.

Management goals of MoSI are to (1) use research results to inform habitat conservation and management, and (2) evaluate management applications.

Migratory Connectivity

In addition, to primary MoSI goals (above), biological samples and measurements collected at MoSI stations contribute to our knowledge of migratory connectivity - i.e., the determination of where local populations of breeding migratory birds spend the winter (and vise versa). MoSI cooperators have contributed thousands of cloacal swab and feather samples to the Center for Tropical Ecology at UCLA for genetic and stable isotope analyses aimed at linking breeding and wintering populations (read more here). Wing measurements taken at MoSI (and MAPS) stations also show patterns of spatial variation in body size that can lend insight into migratory connectivity. (www.birdpop.org)"
