I learned just now that a group of flamingos has a variety of designations. You can call a group of them a pat, a colony, a flurry, a regiment, a stand or a flock. Though my favorite is a flamboyance.
These flamingos were flying in rough formation for our benefit as we rounded the east end of Tortola in the British Virgin Islands. I was lucky to have my telephoto lens on my camera when then suddenly took flight and circled overhead.
