Description
The Laughing Gull is a medium-sized gull known for its distinctive, cackling call that sounds like human laughter. It features a dark slate-gray back, white underparts, black wingtips, and a striking black head during the breeding season which turns white in winter. Their flight is buoyant and graceful, often soaring effortlessly over coastal waters.

Uniform pale grey or soft dove-grey vane with a white base and margins, featuring a prominent yellowish-white central rachis
Barb Structure
Pennaceous upper portion with tightly interlocked barbs and barbicels, transitioning to a plumulaceous (fluffy) downy base near the calamus
Rachis & Barb Pattern
Central rachis is robust, pale yellow-white, tapering smoothly toward the tip with good flexibility; barbs are densely packed and uniform
Texture & Surface
Smooth and soft texture with a matte finish, flexible vane that yields easily to pressure without permanent deformation
Feather Placement
Body contour feather, likely from the upper breast, mantle, or scapular region, determined by its broad shape and semi-fluffy base
