On 29th<\/sup> April 2020, the above White-breasted Waterhen\u00a0hopped up on this\u00a0wooden fence in front of me and allowed close observation and images. It was feeding on insects on the foliage.<\/p>\n

Waterhen foraging in a pond.<\/p>\n

On the early morning of 2nd<\/sup> May, a waterhen was seen foraging in the centre of a pond covered (coated) with Lemna minor<\/em> (Common or Lesser Duckweed). It was sieving through the aquatic plants looking for snail prey, some were tiny as seen in the image below .<\/p>\n

An older video and DSLR images of a\u00a0White-breasted\u00a0Waterhen\u00a0(Uwak) making less commonly heard calls. Many of us would be familiar with the \u2018classical\u2019, calls these birds make \u2013 a cacophony of loud, raucous notes that are answered by the mate \u2013 often sounding like its local name \u201cuwak-wak-wak-wak\u201d.<\/p>\n

The bird also has larger repertoire of other calls. One that I hear infrequently is the one shown in the video and sonogram (above). They are discrete, repetitive calls made every 1.2 seconds (16 calls in 19 seconds) and last 0.2-0.3 of a second. Few authors describe them. Craig Robson (Field Guide to Birds of SE Asia 2002) alludes to them as contact calls and describes them as \u201cpwik\u201d.\u00a0Bird that made calls in Post 2 seen below.<\/p>\n
