Have been away for some time, and just starting to catch up. I have to admit, coming across this bird not knowing what it was at the time, was an interesting experience. Northeast of Saigon by about 2 hours.
Crested Serpent Eagle is the largest raptor in Taiwan. This big bird is easily seen soaring in open country during mid morning in a sunny day. There are several eagles living near my resident, so I could photo them when they perch on the pole or tree top. This bird is not a good flyer and I saw other smaller bird harasses this gigantic raptor during the flight. Despite its name, I saw this bird hunting the snails along the river bank just outside my window.
