Black-and-white Warbler female bringing pine needles to nest, photo, Jefferson National Forest, Virginia, 2010

This female Black-and-white Warbler has just arrived at the nest entrance carrying pine needles in her bill. She entered the nest and incorporated the material into her nest on the ground.  The Black-and-white Warbler nests on the ground and this nest was well-concealed both by surrounding vegetation and its integration into the background of leaf litter. The male did not participate in nest building but periodically brought the female food.

The Black-and-white Warbler, compared with most wood warblers, is very early to migrate south. According to Land, Hugh C. Birds of Guatemala 1970, the Black-and-white Warbler is a transient and winter visitor in Guatemala and arrives as early as August. I have seen the Black-and-white Warbler frequently in Guatemala, both at Tikal National Park in the northeastern lowlands of the Departamento de Peten and in the volcanic highlands around Antigua (e.g., the slopes of Volcan de Agua).

At Tikal, my wife and I observed a female Black-and-white Warbler on July 26, 1992 in the "low swamp forest" along a trail southeast of the east end of the airstrip. We also observed single female Black-and-white Warblers on August 4 and August 5, 1998, the August 5th sighting also in the low swamp forest.

Not only is Tikal a vast site of  Mayan ruins with huge pyramids, it is also a wonderful place to observe wildlife including mammals such as Central American Spider Monkey, Yucatan Black Howler (monkey), White-nosed Coati (called Pizote in Guatemala) and Red Brocket (deer), myriad species of birds, and other fascinating wildlife.

I have observed 234 species of birds at Tikal and on February 25, 1985, my wife and I observed 105 avian species without even intending to and just walking around the park on foot.


La hembra de la Reinita Trepadora está parada en la entrada del nido que está construyendo. Ella tiene hojas de pino en el pico para incorporar en la estructura del nido. La Reinita Trepadora hace su nido en el suelo y este nido estaba bien escondido tanto por la vegetación circundante como por la manera en que estaba ubicado entre las hojas secas. El macho no participaba en hacer el nido. Sin embargo, a intérvalos llevaba comida para la hembra.
