This is one of the handsomest of the manakins of Costa Rica and 

 has the most curious habits of any which I have ever seen. It is 

 practically confined to the Pacific slope, from the coast up over the 

 central plateau region to an altitude of perhaps 5,000 feet. It is very 

 rare in the interior and in the Terraba Valley, being most abundant 

 around the shores of the Gulf of Nicoya and in Guanacaste up to an 

 elevation of about 1,500 feet. The native name for the species is 

 "Toledo," an exact imitation of the call note of the bird. I have 

 seen the males jump up and down on a branch, their heads down, 

 wings half spread and feathers ruffled up, uttering at short intervals 

 their note of " toledo " interspersed with the most curious cracking 

 noise, produced by violently snapping the mandibles together. It 

 frequents undergrowth in the forest and scrubby second-growth in 

 particular, but is not seen so much in heavy dark forest.
