Three of these individuals are in full winter plumage, 

 while those from Ybytimi are young birds in their first 

 plumage, being thickly spotted on the breast and sides of 

 body; the grey on the middle and sides of the head in the 

 adult is here replaced by whitish and blackish lines ; the 

 chestnut collar on the hind-neck of the adult is absent in 

 the young. 



[Neatly constructed nest, lined with horse-hair, in low- 

 grown tree (occasionally but rarely on the- "round), elevation 

 about five feet. Male and female both incubate. I shot 

 a male bird once just as it left the nest. Three eggs form 

 a clutch. On one occasion I removed the second egg as 

 soon as it was laid ; in this manner the bird was induced to 

 lay four eggs and then the nest was deserted. — W. F.]
