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.

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.

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!
