“I observed two different family units of Ruby-cheeked Sunbird (Chalcoparia singalensis interposita); one had juveniles near-adult plumage. This pair had juveniles just beginning to moult into adults .
“The above shows the adult male with brilliant metallic emerald-green head and mantel plumage. In the background is a juvenile male.
“Above and below are also of this juvenile male – the first adult male feature to develop is metallic plumage at the scapula or marginal coverts.
“Below is another view of the back of the adult male.”
