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 pale grey. 

 The only note I heard from this species was a sharp pssss. 



Emberizoides macrourus (Gmelin).

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.
