White Crested Tyrannulet

Serpophaga subcristata (Vieillot)

This little flycatcher was added to the known victims of the shiny cowbird when Eugene Gerzenstein found a parasitized nest on 6 November 1960, southwest of Paso Real, on the Solis Chico River, Departamento de Canelones, Uruguay.

CROWNED SLATY-FLYCATCHER

Empidonomus aurantioatrocristatus (d'Orbigny and Lafresnaye)

To the 2 records of this flycatcher as a victim of the shiny cowbird known to us earlier (Friedmann, 1929:105) may be added 3 more: 2 from Manchalá, Tucumán, northwestern Argentina, 20 October 1925 and 10 October 1930, taken by Pablo Girard, and both now in the collections of the Museo de La Plata; and 1 found in Entre Rios, 23 December 1970, by S. Narosky.

BROWN-CRESTED FLYCATCHER

The white-crested tyrannulet (Serpophaga subcristata) is a small species of bird in the family Tyrannidae. It is found in woodland and open habitats with scatted bushes and trees in Argentina, Bolivia, Brazil, Paraguay, and Uruguay. It is closely related to the white-bellied tyrannulet, but unlike that species the belly of the white-crested tyrannulet is yellow. The recently described Straneck's tyrannulet is extremely similar to the white-crested tyrannulet and was for a long time confused with that species; the two are generally best separated by voice.
