Adult in non-hreeding plumage. — Differs from the breeding plumage 

 chiefly as follows : Upper parts earthy brown with little gloss ; under 

 parts, including tail and its coverts, white except a black plastron on 

 fore breast which extends forward on each side of neck; golden collar 

 replaced by a golden yellow band on each side; secondaries and coverts

 breeding and non-breeding plumage. 



''Young. — Generally resembles the winter plumage of the adults, but 

 is alwa3's distinguished by its rufous head, and in the first stage of 

 plumage by the sandy rufous margins to the feathers of the upper surface ; 

 the dusky band of the sides of the neck is feebly indicated and the 

 horseshoe collar on the fore neck is marked by a few spots of dusky 

 blackish ; the white on the primaries is more restricted, but the elongated 

 tips are present." (Sharpe.) 



"Quite abundant about the Laguna de Xaujan, in Mindoro. It runs 

 about over the leaves of water plants, and when approached sinks its 

 body in tlie water until only its head and tail can be seen. When wounded 

 it dives, and sometimes hangs onto water plants below the surface until 

 it dies." (Bourns and Worcester MS.) 



This jacana is abundant in Luzon in fresh-water swamps and on the 

 borders of lakes. 



Genus HYDEALECTOR ^Yagler, 1832.
