Not common ; keeps to the thickets about the borders of heavy 
woodland. Has a pleasant song that is usually delivered from the 
upper branches of some shrub or low tree. 
I find in my field notes on my first expedition to Venezuela the 
record of finding a nest and one fresh egg of this species at Caicara 
on the loth of August, 1898. The female was flushed from the nest 
and collected at the time. The nest was about 30.5 cm. from the 
ground in a tangle of thorny palm stalks. The opening or entrance 
was on one side of the somewhat bulky and roughly flask-shaped 
nest, turned slightly upward and was quite as large as the largest 
diameter of the nest cavity. The nest measured about 16.5 cm. in 
diameter by 25.4 cm. high. It was built of the dead blades of broad 
leaved grasses, sedges and other aquatic plants, lined with soft fine 
rootlets. The one egg found was white, without gloss, ovate in form 
and measured 25.5 x 17.7 mm.

I found this species not uncommon about Maipures on the upper 
river and collected specimens during December, January, February, 
March and April. The American Museum possesses birds collected 
on the Caura in September. October and February. A female taken 
April 5th had a nearly fully developed egg in the oviduct. 
Fresh birds have the eye seal brown ; bill black ; feet jiale grey. 
The only note I heard from this species was a sharp pssss.

Not observed at Bolivar but it was common at Altagracia, Ouiri- 
bana de Caicara and San Mateo de Caicara in certain restricted locali- 
ties, such as marshy places, where tall sedge-grass grows on the open 
savannas. When flushed this bird will only fly for a few yards and 
then drop into the tall grasses.
