The least common of the tailorbirds in Borneo is the Dark-necked Tailorbird (Orthotomus atrogularis humphreysi).
“Saw a very confident male on the trail in primary forest.
“In north-east Borneo is quite different from O. a. atrogularis that occurs in Peninsular Malaysia, Sumatra and the rest of Borneo.
“Almost thought I was seeing a Mountain Tailorbird as the yellow of the underparts is extensive. Said to have more extensive black on breast but this male did not show it. It had a partner nearby and behaved as an adult.

“Phillipps (2014) states that the way to differentiate the 3 lowland Tailorbird in Borneo is to look at the tail colour – greenish in the Dark-necked Tailorbird.”
