มีบทความดี ๆ มาให้ทุกคนที่ห่วงใยโลกของเรา ทุกวันนี้โลกของเราร้อนขึ้น เนื่องจากการนำทรัพยากรธรรมชาติมาใช้จนเกินความพอดี เกินกว่าสมดุลทางธรรมชาติจะช่วยเรา ได้ กว่าที่เราจะรู้ตัวว่าโลกของเราเปลี่ยนแปลงก็เกือบที่จะสายเกินไป ทบทวนดูสักนิดแล้ว หันมาสร้างโลกที่น่าอยู่ให้กับลูกหลานและเพื่อนร่วมโลกของเราที่เขาไม่ได้มีส่วนสร้างภาวะโลกร้อนกับเราเถอะครับ

Although species have responded to climatic changes throughout their evolutionary history, a primary concern for wild species , bird and their ecosystems is this rapid rate of change. We gathered information on species and global warming from 143 studies for our meta-analyses. These analyses reveal a consistent temperature-related shift, or 'fingerprint', in species ranging from molluscs to mammals and from grasses to trees. Indeed, more than 80% of the species that show changes are shifting in the direction expected on the basis of known physiological constraints of species. Consequently, the balance of evidence from these studies strongly suggests that a significant impact of global warming is already discernible in animal and plant populations. The synergism of rapid temperature rise and other stresses, in particular habitat destruction, could easily disrupt the connectedness among species and lead to a reformulation of species communities, reflecting differential changes in species, and to numerous extirpations and possibly extinctions. has increased by approximately 0.6 degrees C and is projected to continue to rise at a rapid rate.

2007 Raptour & Talk I
Thai Raptor Group has organized a birding trip to survey and estimate a population of globally near-threatened White-rumped Falcon. This residential small, forest falcon is found year-round in Thailand and is currently and locally classified as vulnerable to extinction due to habitat loss or degradation. The falcon is sexually dimorphic since the female is more colorful than the male, which is unique in the bird world. The falcon nests in tree holes, built by woodpeckers and barbets. The main prey types are insects, small birds and reptiles, which are hunted by the method of perch-and-hunt technique, that is when the falcon spots a prey it will fly to catch it on tree trunks or the ground. The site is a small patch (less than 10 km2) of deciduous forest that has been encroached with agricultural fields, broadleaved evergreen forest, and a water reservoir. The event is aimed to count individuals of the falcon species, and record other residential raptor and non-raptor species.
Forty birders attended the trip, comprised 2 birder-wannabe kids, 9 university students (from Chulalongkorn, Kasetsart, and Mahidol Universities) and 29 adults. Most birders enjoyed the forest birding walk with cool weather after a downpour in the evening of 16 June, and multiple prolonged and pleasant views of the falcons in the morning of 17 June. Seven species resident raptors were sighted. Eight White-rumped Falcons were observed with 1 adult female, 5 adult male and 2 juvenile. Thus, it is likely that, at least, one brood of fledglings from a single breeding pairs is successful this year. Other raptor species found during the trip were Black-shouldered Kites, Rufous-winged Buzzards, a Black Baza, a Shikra, Collared Falconets and a juvenile Rufous-bellied Eagle. Seventy-seven species of non-raptor species were recorded. Highlights included 5 Oriental Darters, Grey-capped Woodpeckers (the tiniest Dendrocopos woodpecker in Thailand), Fulvous-breasted Woodpeckers, a fast-flying flock of Red-breasted Parakeets, graceful flight of Crested Treeswift, foraging flocks of Chestnut-bellied Nuthatches (of which its plumage is aligned with subspecies Sitta castanea neclecta), and White-browed Fantails showing the routine “steps” of tail fanning and “ flycatching dance” on tree branches and the ground.
Thai Raptor Group feels thankful to all trip-attending birders and is grateful to Leica for financial support for the trip organization and for providing attending birders its high-quality birding optics.

Appearance of Himalayan Griffon
On 31 December, 2007 around 11.40h, bird watchers on the 2000 m elevation ridge of Doi Lang, Chiang Mai, saw 8 of Himalayan Griffons fly past in a south-easterly direction, apparently having entered from Myanmar.Remarkably, another group of 18 Himalayan Griffons was seen at Mae Ngao, Mae Hongson, 1500 m, at 12:15 h on the same day by some other observers. Taken with the earlier sightings at Doi Lang (two on 15 December and one on 22 December), this suggests that at least 29 have entered Thailand this winter

Look out for the “White-faced” Plovers
A distinctive plover has been independently discovered by Peter Kennerley and David Bakewell, working over ten years apart at two widely separated sites, Singapore and Penang.

Male White-faced Plover at Laem Phak Bia (P. Ericsson)
Especially excitingly for Thai birdwatchers, when, after collaboration and careful synthesis of the evidence, the two observers went public with their findings (www.surfbirds.com/Features/plovers1108/malayplovers.html), retrospective records (from photographs taken in Thailand during 2003–2007, at Phetchaburi—Laem Phak Bia—and from Krabi) came immediately to light. Active searches for the tentatively named “White-faced Plovers” in the Inner Gulf since early December 2007 have revealed two to three further birds. One was found and photographed by Suchart Daengphayon and Somchai Nimnuan near the Artemia ponds at Laem Phak Bia on 15 December 2007, while one or two further individuals were present on the beach nearby for three successive weekends in January 2008.
Peter Kennerley and David Bakewell are to be congratulated on their remarkable find, which they are expected to formally publish soon. They consider that the “White-faced Plover” (named for the distinctive white-lored breeding males) is most likely a species with a small, probably threatened, population that breeds S. China and winters in SE Asia.
The Surfbirds article, a well-illustrated and highly detailed account of what is known, is essential reading for anyone who enjoys shorebirds and wants to search for themselves. Observers are encouraged to look for White-faced Plovers and to send their photographs (with date and location) either to BCST Records Committee or directly to the observers (Peter Kennerley: peterkennerley@onetel.net ; and David Bakewell digdeep1962@yahoo.com ).
