In this video by Drone 5, you'll get a bird's eye look at...birds! Isla de la Gaviotas is a tiny island in the Rio de la Plata off the shore of Montevideo, Uruguay. The Rio de la Plata is a gigantic river estuary formed by the Uruguay and Paranha Rivers. Sitting just a half a kilometer from the mainland, it's a major bird site for birdwatching. Amongst the bird species to be found on and over the island are the western cattle egret, the magnificent frigatebird, and roughly a dozen others.
