Animals of Laguna de Apoyo Nature Reserve
Basileuterus delattrii
Chestnut-capped Warbler
The only resident warbler (Family Parulidae) in Laguna de Apoyo Nature Reserve is the Chestnut-capped Warbler,
Basileuterus delattrii. This diminutive bird is found throughout the reserve, in areas where undergrowth is permitted to grow. It
occupies the lowest levels of the forest, alternating between low branches of trees and stems and branches of small shrubs and annual plants. It may
approach within a few meters of careful birdwatchers.

The Chestnut-capped Warbler has recently been described as a distinct species from the Rufous-capped Warbler,
Amphilophus rufifrons, and both names be found in recent literature referring to this bird in Nicaragua.
Most birds low in the forest have dull colors, but not the Chestnut-capped Warbler. Its bright colors are often found in the shadows,
low in the forest, along with a characteristic, repeated chip. Photo Vera Neumann.
The Chestnut-capped Warbler is very common in Laguna de Apoyo Nature Reserve, and seen in practically every birdwatching excursion.

Because the Chestnut-capped Warbler stays low in the forest and is not shy, it is also vulnerable to boys with slingshots. This poor individual was
confiscated from a group of boys in Laguna de Apoyo Nature Reserve by a park guard. Photo Wendy van Kooten.

The Chestnut-capped Warbler has a heavier bill than any of the migratory warblers which accompany it during the US winter.
