After leaving Aparados da Serra National Park during the late afternoon on October 9, 2011, we birded a stretch of forest about 8-9 kilometers north of Cambará do Sul (a municipality in the state Rio Grande do Sul, Brazil). This is a photograph of a White-collared Swift (Streptoprocne zonaris) with its all dark body and white collar that we saw flying above one of the wetland areas near the roadway. This large swift has a shallowly forked tail. There were thousands of small insects flying over the water, and the White-collared Swifts (along with Biscutate and Sooty Swifts) were in a feeding frenzy. Temperatures were in 80's on this partly cloudy, humid day.
