Color
The brown-headed gull’s distinctive coloration plays a vital role in its survival and behavior. The brown head provides camouflage in its coastal and wetland habitats, allowing it to blend in with the surrounding vegetation and avoid predators. The black bill contrasts with the brown head, creating a striking visual cue that is used for communication and species recognition. The white body helps to reflect sunlight, keeping the gull cool in warm climates.
The brown-headed gull’s coloration also serves as a form of sexual selection.
