Hypsipetes batanensis Mearns, Phil. Jour. Sci. (1907), 2, sec. A,
357; McGregor, Ibid, 342.
Pi-uc', Batan.
Babuyan Claro (McGregor); Batan (Mearns, McGregor).
Diagnosis.--"Exactly like topotypes of Hypsipetes fugensis
Grant, but larger, and with the forehead rufescent instead of
cinereous. Measurements.--Type (skin of adult male).--Length, 262;
wing, 130; tail, 127; culmen (chord), 28; bill from anterior margin of
nostril, 20; tarsus, 26; middle toe with claw, about 27. Average of
three adult males including the type: Length, 264; wing, 128; tail,
127; culmen (chord), 28; bill from anterior margin of nostril, 26;
middle toe with claw, about 27. Adult female: Length, 245; wing, 116;
tail, 112; culmen (chord), 25; bill from anterior margin of nostril,
17.5; tarsus, 25; middle toe with claw, about 25.5." (Mearns.)
Five males measure as follows: Wing, 124 to 129; tail, 116 to 123;
culmen from base, 30 to 32; bill from nostril, 18 to 19; tarsus,
22 to 25.
Other than the size there appears to me to be no appreciable difference
between H. fugensis and H. batanensis. The Batan red-eared bulbul
is very abundant in Batan Island where it was found breeding in
May and June. The eggs are salmon-pink, spotted with shades of
umber-brown. Six eggs measure from 30.2 to 32.7 mm. in length and
from 20 to 22 mm. in width.
