The eggs of the Australian Yellow-breasted Sun-bird are of a 
narrow oval shape and almost devoid of gloss. They are pale 
greenish-grey, mottled with brown and pale lavender. In two 
specimens the markings form a distinct zone round the broad end ; 
in another, an irregular cap; and these three examples have, 
moreover, a few black specks and lines within the zone or on the 
cap. Four eggs measure respectively: ‘68 by -47; -68 by °49; 
*63 by °43; °67 by *45. 
An egg in the Crowley Collection (said to be of this species) 
differs greatly from the above, having the ground-colour white with 
blotches and spots of lavender-grey and irregular streaks, scrolls, 
and dots of deep brown, most of the markings being concentrated 
so as to form a zone round the larger end of the shell. It measures 
*68 by “46.
