I have never seen this manakin in any part of Costa Rica except 

 the northern portion of the Caribbean watershed, from the Matina 

 River northward and from an altitude of about 500 feet to 2,500 

 feet, on the Reventazon River below Juan Vinas. They were par- 

 ticularly abundant in the forest north of Guacimo and El Hogar, 

 where a fine series was secured. They have all the usual habits of the 

 manakins, keeping near the ground, in the underbrush and low trees, 

 and prefer tangled jungle to more open forest. When any males are 

 in the vicinity they can always be detected by their odd habit of 

 cracking their mandibles together, and when doing this the elongated 

 jugular feathers are raised.
