MoSI PROGRAM

Monitoreo de Supervivencia Invernal (Overwinter survivorship) of Neotropical Migratory Birds

Funded by: The United States Fish and Wildlife Service – Upper Midwest Division

Additional Partners: the Institute for Bird Populations (IBP) with training provided by the Costa Rican Bird Observatory

Project period: 2020 – 2022

Mist netting and banding through the Institute for Bird Population’s (IBP) Monitoreo de Sobrevivencia Invernal (MoSI) Program.

According to IBP, the MoSI methodological approach of mist-netting and banding birds along established monitoring routes supplements and bolsters traditional monitoring methods already in place.  This method is specifically tailored to provide key information on the conservation challenges of neotropical migratory birds in their tropical habitats and year-round resident birds.  This approach spells out a distinct objective for this project to understanding bird declines and the factors that limit populations.

Implementation of a MoSI mist-netting and banding program will provide the vital rates of bird populations such as adult survival rates, site persistence, and population trends over the long-term (IBP 2019).

Specific activities include a MoSI training course, and regular MoSI mist-netting during two years conducted by established monitoring groups in two communities: Dos Brazos de Rio Tigre and Rancho Quemado.
