Carriker : List of the Birds of Costa Rica. 903 



Its range covers the whole of the Caribbean lowlands, down to Panama 

 and at least as far north as British Honduras, and to an altitude of about 

 2,000 feet. Like the western variety, it keeps within the heavy, dark 

 forest, on or near the ground, and is always easily recognized by its bright 

 salmon-red bill. The nest is placed on the ground, usually at the foot 

 of a small tree or shrub, and much resembles that of the Ovenbird, being 

 domed over with leaves and sticks to match the surroundings, leaving 

 only a small, well concealed opening on one side. The interior is lined 

 with fine fibres and leaves. The two eggs are dull white, speckled and 

 spotted about the larger end with burnt umber. Measurements: average, 

 25 X 17 mm.
