Well, the black egret does. It forms a kind of circle with its wings
(imitate this by making a circle with your arms, hands touching at
finger-tips), forming a feathery umbrella. It wades around like this,
looking between its wings for fishes. Last I heard, no-one was sure
whether the bird does this to cut out glare from the sun, or whether
fishes flee into the shade, obviously not realising that a poised heron's
beak is not far above them.

Read any good ornithology book to find out more.
