On our query, James Eaton said:: Actually two of the same taxon here, both are ‘confusus’. Just that one is close to a cristatus - the brown crowned brown. True cristatus has the brown to the bill, birds with pale fore crown, like your bird, breed further south. Confusus crown becomes increasingly pale towards the mid-crown as you go south to lucionensis. Trust lucionensis has a grey nape too, which the second bird is very close to, but still brownish, which means it is still a confusus. Basically, confusus is an intergradation zone between cristatus and lucionensis. True lucionensis winter further east, Philippines etc, and are very scarce in Southeast Asia even - nearly all are confusus. There are some potential lucionensis from the Andamans, however. Cristatus is of course the usual winterer in India, though confusus I’ve seen in northeast and Andamans, while there are a handful of photos from Western Ghats too.
