A Swallow Tanager perched and alert along the Madre Dios River in the Peruvian Rainforest. The males shiny turquoise coat seems like it would attract the females when breeding but actually it's the other way around. The female approaches the male with a fine curtsey and bobbing motion. In return, the male will also curtsey. The female then quickly flies off, and if the male follows, then they will breed and become a pair.
