Hi Greg,
I have not observed it with black bitterns, but twice now I have observed
mangrove herons flying along, then flipping over and diving into the water,
azure kingfisher-style, before emerging having caught a fish. I have also
observed mangrove herons sitting on ropes 4-5 ft above the water and diving in
to catch fish, exactly as per the diving kingfishers. I've also seen great and
little egrets dive into the water when rapidly approached from above (eg in a
helicopter).
Hooroo,

Subject: Asian Dowitcher & Unusual Black Bittern Behaviour
Two Asian Dowitchers are presently easy to see on the North Pine River near
Brisbane. One bird was found a few days ago at this spot by Andy Jensen.
I saw a Black Bittern several times along the Noosa River at Tewantin along
with Shining Flycatcher. At one point I flushed the bittern at close quarters
and it dived into the water, with its head and neck appearing darter-like
before the bird disappeared. Has anyone else seen bitterns behaving in this way?
