CHERRIE: ORNITHOLOGY OF THE ORINOCO REGION. 3O3 
NyCTIPROGNE LEUCOFYGIA (Spix). 
Caprimiilgus leucopygus Spix, Av. Bras. II. 1823. p. 3. PL 3. 
Nyctiprognc leucopygia Berlepsch & Hartert, p. 90. 
Eye blackish ; feet dusky slate. 
This species was in the Delta Region about Las Barrancas, also at 
Ciudad Bolivar and at Caicara. During the day time these birds con- 
ceal themselves in the dense thickets bordering ponds and streams, 
where they may be found perched on horizontal branches from 30 to 
100 cm. from the ground. They perch crossways of the branch, and 
not infrequently I have seen from two to eight or ten huddled close 
beside one another all facing in the same direction. 
POD.iiGER NACUNDA (A'ieillot). 
Caprimulgus nacimda Vieill., Nouv. Diet. x. p. 240 (1817). 
Two taken at San Mateo de Caicara; male May 19th and female 
May 25th. 
Eye dark ; bill blackish ; feet dusky grey. 
On my previous visits to the Orinoco this species was observed on 
two occasions but no specimens were collected. It seems to keep entirely 
to the open savanna not even seeking the protection and concealment of 
thickets when at rest during the day. 
In my rather long experience as a collector I have met with very 
few birds as difficult to make up into good skins as the present species. 
MICROPODID.E— THE SWIFTS. 
Only three species were included in the Berlepsch and Hartert 
paper, two of which number were collected on the Orinoco proper and 
the third recorded from Suapure on the Caura River. Additional col- 
lecting will almost certainly add to this number.

Cypselus squamatus Cass., Proc. Acad. Nat. Sci. Phila. \'l. 1853. p. 369. 
Claudia squamata Berlepsch & Hartert. p. 91. 
This species was abundant about Altagracia and at Caicara where 
they were frequently observed coursing over the savannas during the 
afternoon, when the sun was hottest. They were noted in parties of 
from twenty to fifty.
