Guapiles. We next saw two males and two females under sim- 

 ilar circumstances up the slope of Turrialba. One morning 

 while sitting at breakfast, a snowy bird was observed crossing 

 behind the house. We at once went outside and were rewarded 

 by seeing five more adult males fly across singly and join the 

 first in the top of an isolated tree in the garden. There were 

 no females and the flock soon made off silently. We did not see 

 them again nor could we find a nearby fruit tree in which they 

 might have been feeding. 



Manacus candei (Parzudaki). Cande Manakin. 



On April 15th, while following a tramway up the slope 

 about two miles north of Guapiles, a loud snapping noise was 

 heard emanating from the bush. It was a curiously familiar 

 sound and seemed worthy of investigation. On penetrating the 

 tangled underbrush for a hundred feet or so, a tiny glade was 

 disclosed, about which a number of brilliant black, white and 

 yellow birds were flitting. As soon as one perched for a second, 

 it was recognized as Manacus candei. There were about twenty 

 in the flock, the sexes approximately even. All were moving 

 actively through the bushes, feeding on insects. Often a sombre 

 green female would emit the single shrill call-note, which would 

 be answered by several males. The males, besides the call note, 

 snapped their beaks frequently, making a sharp sound, audible 

 at a considerable distance. They also made a crackling noise, 

 which seemed to be a very rapid series of beak-snappings. This 

 was sometimes followed by a curious, deep grunting note. 



The males pursued each other incessantly, moving in short, 

 swift flights accompanied by a loud buzzing sound made by the 

 emarginated outer primaries. 



Very often during a period of several weeks the birds 

 were observed in the same locality. They were never seen more 

 than two hundred or three hundred yards from their favorite 

 glade, and were never seen on the west side of the tramway. 

 There was no water there, and nothing seemed to distinguish the 

 spot from the surrounding jungle. 



One male examined was in breeding condition. The stom- 

 ach contained the remains of some small fruit, as well as the 

 hard parts of insects.
