The 2014-15 MoSI, or Monitoreo de Sobrevivencia Invernal (Monitoring of Winter Survivorship), protocol banding season for the Nicoya Peninsula Avian Research Station is now in the books. Here we have four species, in the form of Neotropical migratory warblers, that were banded and recaptured over the years at the station: the Tennessee Warbler (Oreothlypis peregrina), Black-and-white Warbler (Mniotilta varia), Prothonotary Warbler (Protonotaria citrea), and Northern Waterthrush (Parkesia noveboracen). Banding research is critical to gain an understanding of where and why they return to certain habitat types in Costa Rica. One Northern Waterthrush was recaptured this year after being banded three years ago, meaning it traveled at least an astounding 10,000 miles (and soon to be counting!) during its lifetime.
