Rusty-margined Flycatcher (Myiozetetes cayanensis) Science Article 1
In March-May 1999, I conducted observations on breeding ecology of Rusty-margined (Myozetetes cayanensis) and Social (M. similis) flycatchers along the coast of the Barro Colorado Island located on an artificial lake Gatun. The lake was created during the building of the Panama Canal. The island, a naturereserve, has an area of 1642 ha. It is covered mainly with moist tropical forest. A few dozen pairs of Mangrove Swallows (Tachycineta albilinea) nested near the island. Nests were placed in cavities of dead trunks, trees and branches emerging from water around the island. Such nest sites are typical of the species although the swallows may breed also in nest boxes (Ricklefs 1971, Dyrcz 1984, Turner 1989).
