(2109) Leucopolius peronii.
THE MALAYAN KENTISH PLOVER.
Charadrius peronii Schlegel, Mus. Pays-Bas, p. 33 (1865') (Borneo).
Vernacular names. None recorded.
Description. Similar to L. a. alexandrinus but in breeding plumage the white band at the back of the neck is succeeded by a broad black band linking with the black breast-patches,, whilst in "Winter these patches are rufous and not black.
Colours of soft parts. Iris dark chocolate-brown; bill black, orange at the base; orbital skin orange feet grey, claws black (Everett).
Measurements. Wing 92 to 103 mm.; tail 39 to 41 mm.; tarsus 28 to 30 mm.; culmen 14 to 15 mm.
Female has no black band across the forehead, whilst the black band above the scapulars and the breast-patches are brown mixed with rufous.
Distribution. The islands of the Malay Archipelago, Java to the Philippines, Borneo and the Celebes.
Nidification. Whitehead obtained young birds, almost fully fledged, and three eggs in Luzon on the 26th of May. The groundcolour was " pale cream, the whole shell with small blotches, streaks and zigzag pencilling of rich sepia and pale lavender." The measurements were 30 mm. by 42 mm.
Habits. Those of the genus. This is a resident bird throughout its habitat and nowhere overlaps any breeding race of alexandrinus from which it differs only in its black collar on the back; it should, perhaps, be considered merely a subspecies of that bird.
