Go to a reference book and it will generally list them as birds of Indo-China with scarce reference to them being in Singapore. On the other hand personal reports have them thriving here. Most birders and photographers are likely more aware of the smaller, more handsome Coppersmith Barbet that repeatedly chonks from the treetops. The Lineated Barbet with the green wings and back and vertically striped buff and brown front has large eyes surrounded by a yellow hood. With this species it is easy to see the connection between dinosaurs and birds. Their call is quite strident and loud and not to be mistaken with other calls. Pok Zin noticed activity around a nest hole rather high up in a semi-dead tree. The hole was 40-50ft above ground level and you needed to start with 700mm worth of lens to catch any of the action. On the plus side you had ample time to see the incoming parent and the early morning sun was right at your back. You needed a nice blue sky in the background to get the best shots. »Barbet brood successfully raised By Graeme GUY; photographer: Pok Zin »Birds in My Backyard — Punggol 21 By James WONG »The Joys of Bird Photography By FONG Chee Wai »Black Shouldered Kites, Episode 3.

By Dennis HO Long-tailed Parakeet pair White-throated Kingfisher Pok Zin, Chee Wai and I spent regular times on the nest to try and capture the key moments. To anyone that has doubts about photographing nests we were actually so far away the birds would have hardly noticed us. There were other species of birds the barbet pair were more concerned with. Gangs of glossy starlings frequently loitered on the top branches of the tree and appeared to have interests in other holes. One of the barbets would fly amongst them to disperse them if they got to close to the active nest. Long tailed parakeets would occasionally visit the tree and check out likely nesting sites and a Coppersmith Barbet spent a good amount of time chiseling out a higher nest hole. Blue-tailed bee-eaters, masters of flight, would occasionally alight on a branch and beat a captured insect before consuming it. White-throated and Collared Kingfishers came and went as did several species of woodpeckers. At one point a Banded Woodpecker came too close to the nest hole and was chased off by one of the adult Barbets. Coucals drifted in and out of the bush and one day an unidentified raptor burst from the undergrowth in hot pursuit of a Jungle Fowl and Coucal. The tables seemingly turned the next day when the raptor was pursued by a scolding Racquet-tailed Drongo. There were the omnipresence of yellow-vented bulbul pairs and occasionally Straw-headed bulbuls sang lustily on the nearby bush-tops. 3 Hornbills were seen briefly on a nearby tree until a fragile branch broke under their combined weight and all flew off. The Barbets also saw off a female Koel who fancied their nest http://www.naturephotosociety.org.sg/ASP/Article.asp?DBAPublishDate=3/1/2006 »Keoladeo Ghana National Park, India By David BEHRENS »The Ospreys of Rottnest Island - Part 2 of 2 By Graeme GUY »The Ospreys of Rottnest Island - Part 1 of 2 By Graeme GUY »Macro Photography Not Just About Getting Close By YEO Wee Han »Africa's Best By John MILBANK »Flash as Main Light Page 1 of 5 ::::-=> WELCOME TO ASIA NATURE PHOTOGRAPHY SITE <=-:::: 11/2/08 6:49 AM under their combined weight and all flew off.

Barbets are fruit eaters and the majority of the incoming food was berries. Occasionally a large insect, to provide instant protein was delivered. Both parents, who look similar, took turns in removing beaks full of excrement. The parents flew in from all directions and sometimes would fly straight to the hole. On most occasions they preferred perching on a lower branch before flying up to the hole. Around two weeks after the possible hatching the chicks’ beaks could be seen at the nest entrance. As they grew older they would, one at a time, peer further Straw-headed and further out of the nest. »Mandai Orchid Gardens By Alex YAP »Tripod & Head for Nature Photography By Alan YEO Bulbul Phillipine Glossy Starlings Around 17 days after hatching one of the chicks just flew straight from the hole into the treetops nearby. It returned a bit later to the parents pre-feeding perch and this seemed to confuse the parent flying in with food…..one berry for the chick on the perch and the rest delivered into the nest. The next day the remaining chick or chicks had also left the nest. The parents feeding behaviour appeared to change subtly before the chicks fledged. They would often fly up to the nest hole without food…..the chick seemed to peck frustratingly at the feet of the adult. The nest action was best shot at high speed, to catch the parents coming in with food and the chick waiting with anticipation. Good light was essential and the ISO was cranked up to 800. I used the EOS 1D Mark2 with the 500mm lens and the 1.4x converter (images were too soft with the 2x converter). Speeds of 1/3200 at f10 proved to be the best. I focused on the hole and machine-gunned when the parent approached. You had to do your best to get on the same plane as the incoming bird but this was nullified somewhat by a branch that came into play behind the nest or a pesky tree on the ground that was planted in the wrong place. You just had to hope then the wings would be in the right place or the focus was good. It was a numbers game and possibly 6-10 good shots came from 1200 contenders. Most of the images shown are cropped considerably. This was a fun place to shoot as there was so much action all around and it was a learning process. The company of other like-minded photographers was also welcome. http://www.naturephotosociety.org.sg/ASP/Article.asp?DBAPublishDate=3/1/2006 Page 2 of 5 ::::-=> WELCOME TO ASIA NATURE PHOTOGRAPHY SITE <=-:::: Adult Lineated Barbet on pre-feeding perch 11/2/08 6:49 AM Delivering the berries Adults face to face Arriving at the nest hole Chasing off a passing Banded Woodpecker Poised to launch from the nest The Barbet rocket is launched http://www.naturephotosociety.org.sg/ASP/Article.asp?DBAPublishDate=3/1/2006 Page 3 of 5 ::::-=> WELCOME TO ASIA NATURE PHOTOGRAPHY SITE <=-:::: 11/2/08 6:49 AM A chick appears at the nest hole More incoming food Face to face with the hungry offspring Ready for the next feeding The conveyer belt continues http://www.naturephotosociety.org.sg/ASP/Article.asp?DBAPublishDate=3/1/2006 Page 4 of 5 ::::-=> WELCOME TO ASIA NATURE PHOTOGRAPHY SITE <=-:::: Another delivery of berries 11/2/08 6:49 AM Effluent is constantly removed from the The refuse rocket launches nest The chicks get very inquistive prior to leaving the nest Leaning from the nest prior to launching onthe maiden flight Copyright© 2002- 2008 Nature Photography Society (Singapore).
