Ring-billed Gull

A striking feather featuring bold dark brown and white barring, characteristic of an immature or subadult Ring-billed Gull. The adult Ring-billed Gull is a medium-sized, familiar gull with a clean white body, gray back, yellow legs, and a sharp yellow bill marked with a distinctive black ring

Distinctive white base feather with prominent, evenly spaced dark brown to blackish-brown barring across the vane and tip, typical of subadult or immature plumage

Pennaceous vane with tightly interlocked barbs and barbicels, firm and intact condition

Smooth, matte finish with firm resistance, designed to withstand flight aerodynamics and repel moisture

High-contrast dark brown transverse bars or spots on a clean white background, moderate size, and robust gull feather morphology

Coasts, lakes, rivers, agricultural fields, and urban areas such as parking lots and landfills

Widespread across North America, breeding near lakes and rivers, and wintering along coasts, southern states, and Central America

Acts as an opportunistic scavenger and predator, helping recycle organic waste and maintaining coastal and inland aquatic ecosystems

Herring Gull and California Gull, though Ring-billed Gulls are smaller and subadults display distinct, neat black-and-white patterns on their wing and tail feathers

Ring-billed Gulls are highly adaptable urban foragers, often seen congregating in large numbers in parking lots and fast-food drive-thrus where they scavenge for food

Good condition, showing minimal wear or fraying, likely a recently dropped feather from natural molting
