take. Ultimately the rightful owner returned and was 

 secured. 



One egg had disappeared. The nest was vireo-like, 

 cup-shaped, suspended from the forked twigs. It was not 

 very firm, light showing through it everywhere. The mate- 

 rial was coarse grasses and thin rootlets. Cobweb was used 

 where the nest was in contact with the twigs, and several 

 dead leaves were loosely attached with this material to the 

 outside of the nest. The diameters of the nest were, 70 mm. 

 outside, and 50 mm. inside; the depths, 50 mm. outside, and 

 40 inside. 



The egg measured 21 by 15.5 mm. The ground color 

 was dull yellowish wliite, with numerous pale brown and lilac 

 markings, mostly linear, running lengthways, and more nu- 

 merous around the larger end. 



Two days later, on INIarch 10, I sat down in a small 

 glade near the same animal trail. It was early morning and 

 the sun was not near its full strength. I listened to the chirps 

 of birds drinking at a black jungle creek near by, and 

 watched a hummingbird pick cobweb in the intervals of vio- 

 lent battle with another species. Then a female manakin 

 whirred ])ast and I followed her as she fed on small berries 

 near the tops of some saplings. After fifteen minutes of 

 this fitful occupation she swooped downward, straight to a 

 tiny nest which to this moment had been invisible to me. 

 Here, suspended from a slender fork just over a pool of 

 black water she brooded two eggs. 



A week later the young birds hatched, and on March 

 20, I photographed and examined the three-days-old young. 

 One of them, a female, was reddish flesh color, with yellow 

 gape and yellowish brown legs and feet. The eyes and the 

 upper surface of the wings were dark leaden. 



The down was sparse, long and wliitish grey in color; 

 there was none on the hind leg, but a line of six, strong feath- 

 er sheaths with long down attached along the outer aspect of
