Cheeks pale brownish, separated from the whitish chin and throat bj- 
a narrow dusky brownish submalar streak, sides of breast brownish, 
paler and inclined to buffy in centre of breast. Belly whitish, flanks 
bufify yellowish brown with dusky shaft streaks. Under tail-coverts pale 
yellow. 
A specimen in juvenal phmiagc, taken May 17th, in company 
with both parents, which were also collected, is olive brown above and 
wood Ijrown below with paler throat and crissum ; the wing and tail 
quills are similar to those of the adult female Init with the olive yel- 
low quill edgings less pronounced. 
The parent birds taken with the young described above indicate 
that the males begin breeding before having acquired the fully adult 
dress. The male in this case is similar to those described above as 
"immature" and is in what might be more specifically termed the first 
nuptial plumage. 
Four nests of this species were found on the 1905 expedition. 
One, which was not taken nor the eggs secured, was placed in the hol- 
low of a horizontal limb about 4.5 m. from the ground. The second, 
taken June 17th, was in a sand bank in an old nest-holc of the large 
Ivingfisher, Mcgaccrylc torquata. 45.7 cm. l)ack from the mouth. The nest, 
which was rather deeply cup-shaperl, was embedded in the sand as though 
a hole had been scratched for its reception. Inside it measured 
2.2 cm. deep by 2.9 cm. in diameter. It is constructed entirely of 
fine rootlets and dried grass-stems. The four fresh eggs found in 
this nest are short ovate in form and measure 16.5x13.5. 17x13.5 
and 17x13 and 17x13 mm. respectively. They are pale nile blue 
speclcled with vandyke and seal brown, the spots forming a ring about 
the larger end. 
The third nest was found June 17th. This was placeil about 91.5 
cm. up in a crevice between the rocks in a stone wall. The eggs 
were fresh. One is rounded ovate in shape and the remaining three 
short ovate. They measure 13x15, 13x16, 13x16 and 13.5x16.5 
mm. The color is as in the set described above, but the aggregation 
of spots alx)ut the larger ends is not so pronounced. The parent bird 
was shot as she left the nest and is the adult female described above. 
A nest found April 28, 1898, at Quiribana de Caicara contained four 
eggs with incubatiqn far advanced. This nest was situated behind 
the loose bark of an old rotten stump about 30 cm. from the ground. 
The nesting materials consisted entirely of soft dry grasses.
