2018 International Migratory Bird Day Festival

At Osa Birds fifth-annual International Migratory Bird Day Festival, children danced in the streets dressed as flamboyant, richly colored birds, holding feathered wings aloft.  An integral piece that gives flight to this event is the Tropical Wings annual Birdathon, a concentrated bird species count which takes place throughout the southern Pacific coastal range of Costa Rica including Osa’s sparkling Golfo Dulce and richly bird-abundant Osa Peninsula, named one of the most biologically intense areas of the world by National Geographic.

White-crowned Sparrow

New About Town This juvenile White-crowned Sparrow (Zonotrichia leucophrys) showed up mid November in the town of Rancho Quemado on the north end of the Osa Peninsula.  It was first observed by Yolanda Rodriguez Corrales who is a member of the Biological Monitoring group of the community.  This is the first time this species has come this far south in its winter range to our knowledge, and believe me, it is a topic of conversation and new visitors to the area. While morphological differences are very slight between the male and the female,...

Featured Bird: Chestnut-sided Warbler

Simplemente porque es de la famila Parulidae, la familia con más representantes de aves migratorias en la Península de Osa, les traigo la Reinita de costados castaños (Setophaga pensylvanica), la reinita y ave migratoria más común que se encuentra aquí.  De solo 10 cm de largo, esta pequeña es mas reconocida por la línea colorada (costados castaños) bien definida por los lados en el plumaje del macho. También se conoce por andar con la colita hacia arriba, de la manera muy parecida a los Polioptila (gnatcatchers). La Setophaga pensylvanica se...

Featured Bird: Black-cheeked Ant-Tanager

This months highlighted bird is very special in two ways because not only is it the bird that launches Osa Birds organizational website, but because it is also the only bird species endemic to the Osa Peninsula.  No other bird carries with it this auspicious title.  Partly because of its highly restricted range and also due to the anthropogenic pressures to its habitat, it is considered to be an endangered species according to the International Union for the Conservation of Nature and BirdLife International.  This makes this bird a high...
