The eggs of the Malayan Yellow-backed Sun-bird are of a broad 
oval form and without gloss. The ground-colour varies from 
pinkish-white to pale salmon-pink, and the markings are of two 
types. In one, which appears to be the commoner, the egg is 
marked with large clouds of a darker pink than the ground-colour, 
and is also spotted and otherwise marked with rich purplish-red 
and chocolate-brown. In the other, the egg is densely streaked 
and mottled with rich chestnut, and has no other markings except 
a few specks of deep purplish-red, almost black in intensity. 
Specimens measure from °52 to *6 in length, and from °4 to -43 in 
breadth.

The eggs of the Black-bellied Yellow-backed Sun-bird are of a 
somewhat lengthened oval shape and devoid of all gloss. ‘They are 
pale pink, mottled with chestnut, the markings being extremely 
dense at the broad end and forming a zone or cap at that part. In 
one or two specimens a few very fine hair-like lines may be noticed 
at the broad end. 
One example differs from the above, and resembles the eggs of 
GZ, siparaja of the first or commoner type. 
Two examples measure respectively: *65 by ‘5; *68 by °48.
