AVES TYKANNIUyG. 789 



"The nest is placed in a fork, in the stem of a shrub from 3 to 5 feet 

 above ground. The eggs are three in number. I fancy both birds as- 

 sist in the incubation. At Rio Bueno, January seemed to be their proper 

 nesting-season, or perhaps the end of December, as I found a young 

 bird half fledged about the second week of January. This was the only 

 young bird I found, and I left it to get a little more forward ; but on re- 

 turning a few days later it was not in the nest, and I could not find it, 

 though I knew by the old birds it was near. I believe, from the conduct 

 of the latter, they suspected my intention and had concealed it, as it 

 would not otherwise have left the nest so soon. 



"These birds appear to feed entirely on insects caught on the wing, 

 though perhaps they get them on branches of trees as well, but I never 

 saw them search for food except in the air. 



"I seldom heard the song of this bird, but it is occasionally indulged 

 in by the male at the commencement of the breeding season. I cannot, 

 however, say much as regards its vocal powers, as, though not unpleas- 

 ant, the strain is so subdued as to be heard only when close at hand, and 

 the execution is bad, being very abrupt, as if the performer would not 

 trust his voice. 



"It appears to be a delicate bird and is easily killed; I do not think it 

 could be kept in confinement." (Ibis, pp. 30-31, 1897.)
