With the exception of T. caligatus, this is the most abundant and 

 widely distributed member of the family in Costa Rica. It is found 

 over the lowlands of both the Caribbean and Pacific from one end of 

 the country to the other, and gets up to 2,000 or 3,000 feet in occa- 

 sional instances. It is strictly a forest bird, not frequenting the open 

 woodland and scattering trees as does T. caligatus, but usually lurking 

 in the thick, dark parts of the forest, and, as a rule, keeping rather 

 near the ground. 



I found a nest of this species at El Pozo de Terraba, June 21, 1907. 

 It was in the hollow trunk of a small palm tree, broken off about five 

 feet above the ground, and excavated for a distance of about ten inches. 

 No nest was made beyond the small particles of decayed wood at the 

 bottom of the cavity, upon which lay the eggs. The two eggs were 

 fresh, white in color, slightly glossed, but not polished, and measured : 

 26x22 and 27x21 mm. 



I have also seen the nest of this species made by digging out a 

 cavity in an old termite nest.
