Red River Island, Hanoi, April 20th-May 1st

IMG_6115 (2)
Chinese Hwamei, a bird that has been hunted to near-extinction in Vietnam, but which turns up occasionally in Hanoi. This bird was singing loudly on my balcony one morning, within earshot of the Red River Island, and I saw another later the same morning in the North Wood. We must assume the origins of these two to be dubious at best!

I visited the Red River Island on eight mornings between April 20th and May 1st, spending almost all of my time in the North Wood and surrounding areas of grassland and farmland. Happily no one seemed to be bird-hunting in the area during the period, and the destruction of the North Wood has been temporarily suspended. In fact, one good strip of habitat in the wood is still completely untouched – I was told that the family who own this strip haven’t got around to cutting it down yet. The felling of the remaining trees seems inevitable but I am crossing my fingers that they wait just a couple more weeks until spring migration is over ….

On the negative side, the overgrown field immediately to the west of the North Wood – a favorite recent haunt of Japanese Quail – has now been destroyed and planted with crops, and a decent patch of trees and scrub to the south – which hosted a male Siberian Thrush early in the period – was bulldozed overnight to become just another bare earth field.

Yet more habitat destruction on the Red River Island. Until a week ago, this was an interesting patch of trees and scrub which hosted a male Siberian Thrush on April 21st.

Bianchi’s Warbler – one on 20th. Distinctive call, a soft, slightly cracked-sounding “heu”. Other seicercus warblers seen during the period didn’t call, so ID not certain, but they resembled Bianchi’s in plumage with greenish forehead and crown-stripes not extending to bill base.

White-crested Laughingthrush – one, almost certainly an escapee, on 1st, accompanied by a second bird that resembled a White-crested Laughingthrush but had apparently been dyed yellow.
Chinese Hwamei – one in the North Wood on 22nd. There is also a long-staying bird just outside the area, singing regularly in gardens near my house off Phan Lan Street, and photographed on my balcony on the same date as the North Wood bird. Presumably both birds are of dubious origin!
Dark-sided Flycatcher – singles in the North Wood on four dates.
