Three eggs of the green-backed tailorbird from Isabela Province, Luzon,
collected by Whitehead on May 29, 1894, are described as follows:
"Shape ovate. Ground-color pure white, thinly spotted and dotted
all over with brown-lake over-markings and a few pale reddish lilac
under-markings. Measurements 16 mm. by 13 mm.
"The nest of the green-backed tailorbird is of the ordinary type,
being a pocket formed by two leaves sewn together. It was placed among
the herbage by the side of a path about 8 inches [20 cm.] from the
ground. On the 19th of May a second nest was found on a small islet
in a stream where a few slender large-leaved plants were growing
just above the water. This nest contained two young birds." (Grant
and Whitehead.)
