Seagulls, opportunistic scavenging birds found on shorelines and in parking lots, can typically live from 15 to 20 years. Seagulls are omnivores and can easily find food sources in both urban and coastal habitats. Seagulls congregate in wide open spaces to defend against predation.

Seagulls mate from April to May. Females typically lay two or three eggs that incubate for three weeks. Seagull chicks that are born in June are fully fledged and able to fly by August. Seagulls build their nests on the ground in high grass near naturally occurring obstructions to shelter them from the wind and other gulls.
