Habitat: Ex-logging trail through mixed secondary jungle bordered by primary jungle.
The Rufescent Prinia is unusual in that it makes a nest very much like that of tailorbirds. I noticed a pair carrying prey and, after some time of observation, managed to locate the nest. They had built a nest on a slope along the logging trail, 0.5-0.6 metres above ground. The nest used two leaves stitched together with silk (spider web) used to plug holes. Some of the silk was stretched and pulled into another hole or across opening of the two leaves. The nest was padded with dried grass and other vegetable matter. An overhanging leaf gave some camouflage. Stitching is not as neat or comprehensive as I am used to with the Common Tailorbird. Madoc is noted to have observed that the nest of the Rufescent Prinia is not lined with tree cotton like the Tailorbirds.
Animal prey brought to the chicks included a small grasshopper, small white objects possibly aphids, small invertebrates, etc.
Disclosure re. nesting interference:
Total time near the nest was about 50-60 seconds. Closest approach to the nest was 3 metres for some quick images. The rest of the 45 minute observation was conducted from a safe distance (excess of 15 metres) with minimal images. I did not approach the nest to look into the opening from above. - Amar
