Habits. The following notes are copied from Beebe (Tropical 

 Wild Life in British Guiana,-p. 221) :— " Idly I watched a tiny 

 bird, a flycatcher, flitting about overhead, in the very summit of 

 a iiumgo tree. Presently it dived into a bunch of moss, one of a 

 dozen on some dead branches, but did not immediately appear

 insatiable, inexplicable will-to-learn — the fluid life, as Bergson 

 would have it — overcame the sloth of the material body, and up 

 I went. I climbed swiftly, so that I might keep beyond the ever- 

 increasing area of irate ants, and finally tracked the branch. My 

 flycatcher shot out, and raising his diminutive crest, scolded me 

 roundly for my unwarranted intrusion. The nest was most 

 ingeniously hidden, and I could not find the entrance until I had
