Laughing Gull

Identification

The laughing gull is a medium-sized gull measuring 36–41 cm long with a wingspan of 98–110 cm and weighing 203–371 grams. In summer plumage, adults display a striking appearance: a white body contrasted with a dark grey back and wings, and a distinctive black head. The long, pointed beak is bright red. A key field mark is the wings, which are much darker grey than other similarly-sized gulls, with black tips lacking the white crescent visible on Franklin's gull. In winter, the bold black hood is mostly lost, making identification more subtle.

Immature birds present a challenge for field identification, as they take three years to acquire full adult plumage. First-year birds are greyer below with paler heads and an all-black tail, appearing darker overall than most similar-sized gulls except Franklin's. Second-year birds can be distinguished by their wing pattern, showing more extensive black on the primary coverts, and sometimes retaining traces of black on the tail. The species takes its English name from its distinctive raucous call—a high-pitched laugh sounding like "ha... ha... ha..."—which is unmistakable once learned.

Range & habitat

Laughing gulls breed along the Atlantic coast of North America, throughout the Caribbean, and into northern South America. Two subspecies are recognized: L. a. atricilla ranges from the West Indies to the Venezuelan islands, while L. a. megalopterus occurs from southeast Canada down through Central America. Northernmost populations migrate farther south during winter months, and the species occasionally appears as a rare vagrant to western Europe.

The species shows a strong preference for breeding in large colonies on low-lying coastal islands, where they build nests from available vegetation. Colony sizes vary dramatically, ranging from just a few pairs to enormous aggregations of 25,000 birds or more, making them conspicuous features of coastal landscapes throughout their range.

Behaviour & diet

Laughing gulls are opportunistic omnivores and aggressive scavengers, taking advantage of whatever food sources are readily available in their environment. They breed in large, sometimes enormous colonies on low-lying coastal islands. Breeding begins from late April in southern populations and from mid to late May in northern regions. Both parents participate in nest construction, incubation, and chick-rearing, with eggs incubated for 22–27 days. Chicks remain near the nest for approximately five days before becoming more mobile, and fledge at around 40 days old, though both parents continue to feed and brood them throughout this period.

Best time & places to see it

Laughing gulls are most readily observed during the breeding season when they congregate in large, noisy colonies on coastal islands throughout their range. The breeding period spans from late April through June, depending on latitude. Visitors to the Caribbean, Atlantic coastal areas of North America, and coastal regions of Central America have excellent opportunities to encounter this species. Large breeding colonies make them comparatively easy to locate and observe during these months, though their raucous calls often announce their presence before they are seen.

Photography tips

The laughing gull's bold plumage and contrasting summer pattern make it an attractive photographic subject. The bright red bill and black head are particularly striking and photograph well in clear, bright light. Breeding colonies offer excellent opportunities for behaviour photography, including courtship, nest-building, and chick-feeding interactions. Photographers should be mindful that winter birds lack the distinctive black hood, which can complicate identification in off-season images. The species' gregarious nature and habituation to human presence in many coastal areas means patient photographers can often achieve close approaches and detailed shots of both adults and immatures at various plumage stages.
