Rhynchocyclus flaviventris flaviventris (Max.)- Yellow- 

 green Broad-bill Flycatcher. 



Several of these flycatchers were seen at La Brea and one 

 secured. Their mandibles snapped audibly when they closed 

 upon some small insect prey but their general appearance and 

 motions were of warblers rather than flycatchers. 



Todirostrum cinereum cinereum (Linn.) . Gray Tody- 

 flycatcher. 



Fairly common in the clearings about Guanoco and along 

 the railroad track. One bird perched in a low tree was very 

 tame and not alarmed at the closest inspection. It uttered a 

 single, sharp call-note, and now and then dashed out after a 

 passing insect which it seized with a loud snap of the bill. 

 Within a period of ten minutes it repeated four times a simple, 

 piping warbler-like song, sounding like ivhit-o! whit-o! whit-o! 

 These birds were breeding at this season. 



Todirostrum maculatum (Desm.). Spotted Tody-flycatcher. 



We saw several small flocks of this species on March 26th 

 along the banks of the Cafio San Juan about nine miles from its 

 mouth. They were in family parties of three to five individuals, 

 and were catching insects among the mangroves. Their call- 

 note was a loud, sharp chirp, out of all proportion to so small a 

 bird. They showed no fear of us and came within a few feet of 

 the canoe. 



This is the first time that Todirostrum maculatum has been 

 recorded from the Orinoco region; British Guiana having been 

 thought to be the northern limit of its range. 



Colopteryx galeatus (Bodd.). Helmeted Pygmy Flycatcher. 



On April 8th in the high woods back of Guanoco we first 

 observed this tiny flycatcher. A male bird was perched about 

 thirty feet up in a great tree, uttering a sharp, penetrating chirp 

 at intervals, the sound being audible a long distance away. 

 These birds seem to find a portion of their food in the calyces of 

 flowers and the crevices of the bark as well as by pursuit on the 

 wing. The Indians call them copeton. They were in breeding 

 condition. Besides its extremely long, transverse crest, this 

 pygmy flycatcher is characterized by the degenerate condition of 

 the first three primaries of the wing, which are only two-thirds 

 of the normal length of the other feathers. In its stomach were 

 a number of small insects and one round seed.
