Adult in non-breeding 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 
mostly earthy brown speckled with white. 
Birds in intermediate plumage present endless combinations of the 
breeding and non-breeding plumage. 
“Young.—Generally resembles the winter plumage of the adults, but 
is always 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 Naujan, in Mindoro. It runs 
about over the leaves of water plants, and when approached sinks its 
body in the 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 HYDRALECTOR Wagler, 1832. 
This genus differs from Hydrophasianus chiefly in having a fleshy 
lappet near the base of bill and the tips of the primaries not attenuated.
