The Pegu White-Eye.
Zosterops palpebrosa peguensis Stuart Baker, Ibis, 1922, p. 144 (Moulmein). Zosterops palpebrosa. Blanf. & Oates, i, p. 214 (part).
Vernacular names. None recorded.
Description. Differs from all the preceding forms of Zosterops in its very pale lemon-yellow throat and under tail-coverts. From Z. s. simplex it differs in its much brighter upper parts as well as in having a smaller, less coarse bill. In colour it is like the palpebrosa group but much darker above, where it is olive-green rather than olive-yellow.
Colours of soft parts as in the other races.
Measurements. Wing 53 to 58 mm.; culmen 9 to 10 mm.
Distribution. Southern Burma from Pegu North and East to Karenni and Maymyo. Birds from Siam, Yunnan, to Hainan and Formosa are referable to Robinson and Kloss's Z. s. williamsoni, a rather darker bird above and pure white below.
Nidification, Two nests taken by Macdonald near Thayetmyo on the 17th and 26th of June are described by him as exactly like those of the Indian White-Eye. They contained 3 and 4 eggs respectively. Twenty eggs taken by Mackenzie and Macdonald average 15.6 x 11.8 mm.: maxima 17.0 X 12.0 and 16.7 X 12.2 mm. : minima 14.0 x 11.0 and 14.3 x 10.4 mm. The eggs are of the same pale blue colour as those of the other races.
Habits. Similar to those of the other White-Eyes but it is rather more exclusively a forest bird than most.
