Summary of Records from Red River Island, March 5th to May 16th 2016

IMG_6124 (2)
A rare clear day in Hanoi, looking north from the edge of the North Wood towards the Red River and airport bridge (photo taken on May 16th).

Site: Red River Island, Hanoi, Vietnam (Google Maps location)
Visits/days: 43 visits covering 42 days, between March 5th and May 16th
Months (days) visited: March (15), April (18), May (10).
Species recorded: 176
General notes: At least 90% of my time was spent in the North Wood and surrounding farmland/grassland at the northern tip of the island, with infrequent visits to other areas. Almost all of my visits were between the hours of 7.00am and 12.00pm, with a typical duration of between 2 and 3 hours. I was usually alone, but sometimes joined by other birders – most often Hung Le and Joy Ghosh.

In the table below, the second column indicates the number of visits on which the bird was recorded (out of 43). The third column is the high count for that species. The fourth column contains notes about a species’ status in the area, or other general comments. Thanks to Dave Sargeant (North Thailand Birding) for inspiration about how to present this information!

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.

IMG_6123
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.

Full sightings list from my visits on April 20th, 21st, 22nd, 23rd, 25th, 27th, 29th, and May 1st:

Black-naped Monarch – 1-2 on most dates.
Blyth’s Paradise-Flycatcher – male on 25th.

Claudia’s Leaf Warbler – regular migrant throughout April but not seen since 22nd.
Grey-crowned Warbler – on 22nd, one seen and a second individual heard, distinctive soft double-note call.
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.
Asian Brown Flycatcher – common migrant with high count of 5 on 21st.
Hainan Blue Flycatcher – one on 20th was the last record of the spring – this species was commonly observed in late March/early April.

Red-throated Pipit – single over on 22nd.
Oriental Greenfinch – four on 23rd.
Eurasian Tree Sparrow – occasional individuals recorded, this species is much more common in urban areas.
