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 ground), 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.~\
