We are gearing up for our final MoSI (Monitoreo de Supervivencia Invernal in Spanish or Overwinter Migrant Survival Monitoring in English) bird banding pulse of 2025! Mist nets are a key piece of equipment but the most vulnerable to wear and tear in each banding pulse. That’s why we are asking for your help in purchasing three new mist nets (each $120 USD)
in advance of our upcoming pulse.

Thank you so much for considering a donation today!

*Please note that all of our bird banding efforts are done with the required permits from the Costa Rican government, following all the most rigorous protocols to avoid harm to the birds.
