I spotted a pair of Yellow-breasted Warblers (Seicercus montis davisoni) nesting in the montane forest at Cameron Highlands in Pahang, Malaysia.
I did not approach the nest or attempt to look at it. I stayed about 5-6 meters away. I was watching birds along a road and this pair was actively feeding young and generally comfortable with my presence; entering and exiting the nest while I was nearby.
The nest was located 2.5-3 meters on the slope/bank under the roots of over-hanging trees and bushes; the nest itself was not visible (see composite image above).
Both partners were actively bringing prey. They collected prey from 5-10 meters around the nest site and items I could identify were caterpillars, spiders and Crane Flies (Tipulidae) – see above. Much of the prey was gleaned from the under surface of leaves and ferns. After having observed numerous episodes, on this occasion and previous visits, I am now convinced that fluttering to obtain prey under foliage is a major hunting technique. They have very high-pitched calls but my recordings were poor (and old age hearing loss failed me).
