Sean saw a painting for International Migratory Bird Day 2015 of a Blue-crowned Motmot (Momotus momota) and Black-and-white Warbler (Mniotilta varia), and he was inspired make a quick MYN-style photo of the same scene. Photographed by RTPI Affiliate Sean Graesser for the Meet Your Neighbours global biodiversity project in Costa Rica while on assignment for the Roger Tory Peterson Institute of Natural History.

Here are a couple more goodies from Twan’s yard, a male Black-and-white Warbler (Mniotilta varia) and a male Black-throated Blue Warbler (Setophaga caerulescens). Both certainly look exactly as they sound! Please be sure to eBird all of your yard birds, as Twan did.

The male is darker and more heavily streaked with more black than white.

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...
