Oriental Reed-Warbler in Laem Pak Bia Watertreatment / Thailand

Chinarohrsänger2 warblers are calling out of the reeds in the early morning in the middle of Thailand. The one is a Black-browed Reed-Warbler (Acrocephalus bistrigiceps) this is clear. Checking some older images I stumbled over an Acrocephalus-Warbler, which at the time, I called a Blunt-winged Warbler (Acrocephalus concinens). I shot the image in January 2011 in the Laem Pak Bia Watertreatment plant in middle Thailand. I checked the Helm ID-guide “Warblers of Europe, Asia, and North Africa” and I start thinking due to the streaks on the breast and the thick bill it might have been a Oriental Reed-Warbler (Acrocephalus orientalis) instead. I opened a threat in www.birdforum.com.

Quite shortly, a specialist confirmed the ID with the words “…is indeed an Oriental Reed Warbler. Note in particular combination of grey streaked breast, strong supercilium, rather heavy bill and blue-grey legs.”

In the Laem Pak Bia Watertreatment plant, there are pools designed to purify the water a biological cleaning process with reeds. The staff is very nice; the gate is already open or they open it for the incoming bird-watcher. The swampy, watery or dry, more or less large pools are a perfect place to see many of the usual but also unusual birds of Thailand. This is particularly true in the winter season. Promptly I can see White-breasted Waterhen, Ruddy-breasted Crake and Pintail Snipe. A big flock of Whiskered Tern (Chlidonias hybrida) have gathered in one of the large water basins, which are used for pre-cleaning. There they collect micro insects from the water surface. A great sighting in the first morning light. At the end of the terrain, a flooded mangrove forest is located. In the rear area, just before the mangrove forest, there are a few narrow sedimentary bassins. Just when I arrived 2 warblers are calling from within the reeds. Eventually they come to the edge of the reeds and can be observed.

Bird-lens is mainly a website to suit the growing demand for top shots of the species of the Western Palearctic. Trips to tourist and non-tourist spots like Thailand or the Seychelles to capture images of rare migrating birds are part of the program and were already very successful. More nice images you find in the gallery or in the “Pictures Shop”. Just give me a message, if Bird-lens could serve you with images also outside the range of the Western Palearctic. Images of e.g. South America are well on stock, too. The nice images you find in in the gallery are only a first impression, what you might find in the gallery in the “Picture Shop” too. Just give bird-lens.com a message, if bird-lens.com could serve you with an image needed before other pictures are online.
