Blyth’s Kingfisher, Alcedo Hercules,
One of the very scarce target species for birders visiting NE India. We found this bird sitting on a small branch overhanging a mountain stream en-route to Tenga in Arunachal Pradesh. It was very wary and did not allow close approach. Eventually it flew off upstream and was lost to view amongst the overhanging trees.
You can see the characteristic blue ear coverts, the distinct speckling on the wing coverts and the lack of any greenish was amongst the dark blue on the wings, head and tail. The bill is also dark.
This scarce Kingfisher is at the western end of its range in NE India. It is a bird of rocky forest streams. It also occurs further east from Sikkim to SW China, North Myanmar, N. Laos, North Vietnam and Hainan.
