The Buff-necked Woodpecker (Meiglyptes tukki) is a forest woodpecker species found in South-East Asia. The species is listed as a near threatened due to habitat loss. It is already locally extinct in Singapore, but can still be found in nearby Malaysia.
As the name implies, it has a buff-coloured neck patch. The male has a red submustachial stripe which the female lacks.
(Male, foraging on excavated soil embankment, with insect prey on bill. To get this shot, I has to crouch on the roadside.)
I has an encounter with a family of four of these woodpecker one morning at Panti Forest, Malaysia in July 2013. They were first seen perched on thin branches next to the roadside. There have been some excavation work done to widen drainage and as such, there were loosened earth that exposed insects.
