We took this photograph of a Rufous Hornero's nest during the morning of October 4, 2011, at Reserva Volta Vehla. We were birding near the main clearing while waiting for the weather to improve. The Rufous Hornero uses mud or dung to build its nest in trees or on any suitable man-made object such as chain-link fences (see our Argentinean photographs), telephone or electricity poles. The nest resembles old wood-fired ovens (the Spanish word "hornero" comes from horno, meaning "oven") that can be see outside many homes in rural South America. Temperatures were in the low 70's on this cloudy, overcast morning. The Volta Velha Reserve is a popular birding spot in southern Brazil and is well-known among birders around the world. It is located in Itapoã on the northern coast of Santa Catarina state. The reserve encompasses about 2,300 acres within one of the largest areas of undisturbed Atlantic Forest (lowland rainforest on the coastal plain of Brazil) and is one of the most endangered biomes on earth.
