PLATE 19 



B 



Juvenal, 6 weeks old, Damar ring-dove, St. darmrenm. Shows strong neck- 

 mark in first plumage. The neck-mark is (as In the adult turtle-dove) a sidi 

 spot, not a half collar as in the adult Damar ring. 



Juvenal blond ring, St. risoria, to compare with above. The first feathers slum 

 weaker neck-marks than the Damar ring. The mark in the Mend ring (v 

 present) is also a sick spot instead of a half collar. The turtle-doves show no 

 color in these feathers in the first plumage.
