Thailand Birding: Finding A Java Sparrow

Although I have lived in Bangkok for years I have never taken the effort to go and track down any of the city’s Java Sparrows; there has long been a self-sustaining population of this species, originating from escaped caged birds. However, beyond the vague instructions of “the Don Muang area” I have never known where to look for Java Sparrows

Don Muang is the name of Bangkok’s old international airport, which is only really used for some domestic flights these days - it is in the north of the city. The area is really busy and I live quite far away, so the prospects of hunting these birds down in residential areas and along busy roads was never one that I relished. However, during a phone conversation with Phil Round yesterday, I finally remembered to ask him where I should look for Java Sparrows and he gave me details of a specific place to look that was easy to find.
With the encouragement of my wife, we went and had a look yesterday afternoon. The location is a small compound of apartments belonging to the airforce, right next to the Amari Airport hotel - easy to find. The hotel is on the opposite side of the road from the airport and there are signs for it in English after you have passed the domestic terminal and are about level with the international terminal. You can park in the car park of the Amari hotel, exit the car park and turn right, walk down the street for about 50 metres and you will see the apartments in a leafy compound.
We checked in with security, who made a bit of a song and dance about letting us in, but after a bit of a chat we entered. Java Sparrows were not obvious. After a bit of a search I spotted a pair, high up on a building, sitting above a ventilation window. Soon another pair joined them and the four of them spent a long time just sitting, preening and flitting about, occasionally disappearing beyond the boundaries of the compound but always coming back quickly. After about 30-40 minutes of watching them we left them to their business.
I understand that Java Sparrows are listed as Vulnerable by Birdlife International with a population of only 2,500-10,000 individuals in its native range, Java and Bali. Due to trapping and increased use of pesticides, Java Sparrow populations are declining; the population in Bangkok may be of significance in this light.

Thailand Birding: Asian Golden Weaver

The large majority of birders visit Thailand between the months of November and March, which is a great time for winter migrants but not so good for resident birds.

There are a few birds in particular which just are not present in the dry season or not at their best. Asian Golden Weaver is one of the latter; through the dry season months it is in non-breeding plumage and rather dull, but in the breeding season (late March to August) the male is one of the most fabulous birds of the wetlands.

Over the last few months I have been seeing small nesting colonies of Asian Golden Weavers regularly at Muang Boran Fishponds near Bangkok and Tung Bang Jak near Petchaburi. They make small, ball-shaped nests in emergent vegetation such as Typha whilst their relatives, Baya Weavers, make pipe-shaped nests in trees and Streaked Weavers make a ball with a pipe in emergent vegetation.

Anyone heading to Bueng Boraphet from March to August should also easily see this species by going to the crocodile enclosure at the fisheries research station on the north side of the lake, where they breed, their nests protected by crocodiles.
