t’s easy to spot great egrets around Charleston — they’re those beautiful big, white shorebirds that populate the Lowcountry marshes, stabbing their bills into the water to catch fish and amphibians. But unless you spend hours birdwatching, you probably haven’t seen a great egret the way you will in Brian Koury’s photography exhibit, Birds on a Limb. “He does a lot of outstanding night shots of birds, backlit, with the light coming through the feathers,” says Charleston Artist Guild President Ron Gibb. “They’re extraordinarily nice.” Koury somehow captures the egret’s smoothness of movement, that uncanny ability to appear still even when in flight. Birds on a Limb features photos of egrets and herons flying, stretching their wings, and hunting, always making striking use of the contrast between the snowy animal and its natural setting. Though birds are the focus of this exhibition, Koury is also inspired by water in all its forms, so expect to see a couple of marsh and beach shots as well.
