“My wife and I first saw this Crested Goshawk (Accipiter trivirgatus peninsulae) furiously chasing a Lineated Barbet (Megalaima lineata hodgsoni) yesterday morning. The barbet was yelping in terror – a call I have not yet heard from this barbet. Not sure as to outcome as they flew into some trees.
“Note how the bird likes to sit on one foot, with the other often hidden in the feathers. Occasionally the foot will ‘peep out’ when a gust of wind blows the feathers. I thought it might be a damaged foot but yesterday’s shots show the same action but with the other foot.
“I reviewed past photographs (previous years) and saw the same posture. It does use both feet as well to perch. Wonder if this “one foot perch” is for long durations.”
