Three nests of this species collected within a few days of one an- 
other, and in the same general locality (within an area of a circle, the 
radius of which wonld not exceed 75 metres) seem to the writer excel- 
lent examples of the individual tastes of birds. Each nest is con- 
structed of material distinct not only in its character but 
also in its color. The various materials from my observations 
seemed equally abundant, yet one nest is constructed entirely of black 
fibers and each of the others of a distinct shade and texture of gray- 
ish brown fibers. Xot only was the character and color of the mater- 
ials employed in each case distinct, l)ut the builders displayed indi- 
A-idual taste in the execution and st}le of the exterior of the nest 
structure.

The writer obtained a single specimen, an adult female at Mun- 
duapo, March 15th, 1899. Xo others were observed. Specimens were, 
however, collected by both Klages and Andre on the Caura River at 
Sua])ure and l.a Pricion respectively, and there is a single example 
in the American ^Museum, collected at Pa L'nion, Caura River, by 
Klages.

A not uncommon species fre(|ucnting the sparsely wooded 
savanna regions occasionally in company with species of Myio::cfctcs. 
It was observed at various points from Ciudad Bolivar up as far as 
Caicara. 
Eye dark brown ; bill black ; feet blackish. 
A nest and set of eggs together with the female parent bird were 
collected at Caicara May 6th, 1907. The nest is an open, cup-shaped 
afifair, closely resembling that of our wood-pewee (Myiochancs vireiis). 
It was saddled on to the forks of a good sized limb, about 4.57 m. 
from the ground. The tree in which it was placed stood just at the 
edge of a belt of heavy timber bordering the river. The nest walls 
seem to be composed almost entirely of grey lichens that are bound 
together by cobwebs. There is a somewhat scant lining of fine
