Crimson-fronted Barbet
Small enough to sit in full view and still go unnoticed. It also goes by the name Sri Lanka Small Barbet.
Yellow-fronted Barbet
Heard everywhere in the hills, hard to find among the leaves. Follow the call up the trunk, then wait for it to move.
Red-backed Flameback
A garden bird many Sri Lankans see every week, and it lives nowhere else on Earth.
Crimson-backed Flameback
Compare it with the Red-backed Flameback. The bill colour tells them apart, and few people ever check.
Sri Lanka Grey Hornbill
A hornbill with no casque, easily overlooked for that reason. Listen for the wingbeats overhead.
