The eggs of the Amethyst Sun-bird are extremely variable. 
Two examples in the Collection are regular ovals and of a greyish 
cream-colour, longitudinally smeared with purplish-grey and 
spotted with dark sooty-brown, these markings being much blurred 
and smudged. Two other eggs are narrow ovals and of a darker 
shade of greyish cream-colour, longitudinally streaked and smeared 
with pale lavender-grey and very sparingly spotted with dark 
brown. Other specimens are of quite a different character, being 
cream-coloured, densely mottled all over with brown and lavender- 
erey. Eight examples measure from ‘69 to ‘81 in length, and from 
5 to ‘55 in breadth.
