Gulls in Hawaii: Meet the Rare Vagrant Species That Make It to the Islands
October 2, 2026
Anyone who grew up dodging gulls at a mainland beach picnic might assume Hawaii has the same problem. It doesn’t. Gulls in Hawaii are so uncommon that a single sighting can send local birders scrambling for their cameras, because more than likely, you won’t find seagulls in Hawaii, and there are no native gulls that call the islands their home. Unlike some other bird species, seagulls don’t normally migrate to Hawaii.
That absence has a geological explanation, not a biological one. Hawaii is the most isolated island chain on Earth, situated more than 2,000 miles from the nearest continent, North America. Another reason for the lack of seagulls in the Hawaiian Islands is the lack of a continental shelf. Gulls evolved to hunt along shallow coastal waters, and the volcanic seafloor surrounding the islands simply doesn’t offer that kind of habitat.
Every so often, though, a gull shows up anyway. Those birds that do make it have either flown on their own or got blown off course, or hitched a ride on ships. In either case they don’t stay for long. Two of the more notable vagrants on record are the ring-billed gull and Bonaparte’s gull, and both are worth a closer look.
Key Insight: Birders use the term “vagrant” for a species found far outside its normal range, usually after storms, navigational errors, or long-distance hitchhiking on vessels. A vagrant gull spotted in Hawaii is not evidence of a new resident population; it is a one-off traveler that will likely move on or perish without returning home.
Vagrant records compiled from Hawaiian bird sightings point to a short list of repeat offenders. The most common vagrants are the Ring-billed Gull, the Laughing Gull, and the Glaucous-winged Gull. Visitors hoping to spot something gull-like on a Hawaiian beach are far more likely to encounter one of the islands’ true seabirds, several of which share the white-and-gray coloring that makes gulls recognizable elsewhere. A rundown of these look-alikes is available in this guide to white birds in Hawaii, which covers species frequently mistaken for gulls by first-time visitors.
Hawaii’s isolation has also produced one of the most distinctive bird communities on the planet. Hawaii is home to over 350 bird species, including 50 different endemic birds that cannot be found anywhere else in the world. Many of those endemic species face serious survival pressure, a topic explored in more depth in this overview of endangered animals in Hawaii.
1. Ring-billed Gull
The ring-billed gull (Larus delawarensis) is one of the most frequently documented gull vagrants in the Hawaiian record, and it is also one of the most familiar gulls across the North American mainland. Its willingness to scavenge almost anywhere, from parking lots to garbage dumps, may explain why individuals occasionally end up hundreds of miles offshore.
Physical Characteristics
The Ring-billed Gull is a medium-sized gull with a white body and grey wings. The yellow bill has a black ring midway around it, which gives the bird its name. The legs are yellow, as well as the eyes, which have a red circle. The wings have black tips, as well as the tail. Ring-billed gulls are approximately 18 inches (47 cm) long.
Juveniles have mostly a mottled brown plumage and take three years to reach the plumage of the adult. Because of that lengthy maturation, birders scanning Hawaiian shorelines for a vagrant ring-billed gull need to account for several possible plumage stages, not just the clean gray-and-white adult look.
Habitat, Diet, and Nesting
Ring-billed gulls favor coasts and bays, but also inland spots like parking lots, fields, and garbage dumps, where their diet is omnivorous, including insects, small fish, rodents, crustaceans, and garbage. That flexible appetite is unusual among seabirds; for a broader look at how different species source food in the wild, see this breakdown of what birds eat to survive.
On their home range, ring-billed gulls nest in colonies generally on small islands, often mixed with other gull species. The nest is a simple scrape on the ground, and around three eggs are laid, incubated by both parents, who also share feeding duties. The breeding range covers the southern part of Canada, except most of Quebec and western British Columbia, along with the northern United States. None of that range comes anywhere close to the Pacific, which is exactly why a Hawaiian sighting counts as newsworthy among local birders.
Conservation Status and Sightings in Hawaii
Once hunted for its feathers but now protected, ring-billed gull populations have increased to the point where in some areas it is considered a pest on farms or at airports. The species has adapted well to human environments, modified its diet to include garbage, and is no longer considered at risk. That population boom on the mainland is part of why it turns up as a vagrant more often than most other gull species; more birds on the wing statistically means more chances for one to drift off course. Detailed sighting records and photo documentation from Hawaiian observers can be found through Birds of Hawaii.
Size-wise, the ring-billed gull is modest compared to many other North American birds. Readers curious how it stacks up against true giants of the continent can compare it with the species featured in this guide to the largest birds in North America.
Pro Tip: If a gull-like bird shows up on a Hawaiian beach, check the bill first. A yellow bill with a distinct black ring almost always points to a ring-billed gull rather than one of the larger vagrant species like the western or herring gull.
2. Bonaparte’s Gull
Bonaparte’s gull (Chroicocephalus philadelphia) is a different kind of visitor altogether. Where the ring-billed gull is a bulky scavenger, Bonaparte’s gull is small, buoyant, and almost tern-like in flight, making it one of the more elegant gulls that could theoretically wander into Hawaiian waters.
Physical Characteristics
It is the most common small gull through most of North America, especially inland, and breeding adults have a black head, thin white eye arcs, bright red legs, light gray upperparts, and black wingtips. At 28 to 38 cm (11 to 15 in) in length, it is one of the smallest species of gull.
Outside of breeding season, the look changes considerably. Nonbreeding adults and immatures have pinkish legs and a mostly white head with a black ear spot. That subdued winter plumage is the version most likely to be reported anywhere far from the species’ usual range, since Bonaparte’s gull spends the colder months away from its breeding grounds.
Breeding Behavior and Range
What sets this species apart from every other gull is where it builds its nest. It breeds near water in boreal forest and is the only gull that makes a stick nest in a tree. It breeds solitarily or in very loose colonies in habitats remote from human settlements, around ponds, bogs, bays, and fiords in the taiga and boreal forests of Alaska and Canada, and it winters in large flocks in coastal areas close to human activity.
During the colder months, it is often seen in large flocks along beaches, bays, coves, and lakes, feeding on small fish and invertebrates, often gracefully fluttering around and picking them off the water surface. That foraging style is reminiscent of several other coastal and inland water birds found across the mainland United States, including species profiled in this guide to water birds in Texas.
Naming and Chances of a Hawaiian Sighting
The common name honors Charles Lucien Bonaparte, a cousin of Napoleon Bonaparte who made important contributions to American ornithology while an active member of the Academy of Natural Sciences of Philadelphia during the 1820s. The scientific name traces back to the same city, where the type specimen was originally collected.
Bonaparte’s gull has not established any regular presence in Hawaii, but it isn’t entirely theoretical either. Wikipedia lists the following seagull species as ones with the potential to visit the islands, including Bonaparte’s gull. Confirmed reports remain scarce, and any individual reaching Hawaii would almost certainly be a storm-displaced bird far from the boreal lakes and rivers it normally calls home, according to the range detail documented by the U.S. Fish and Wildlife Service. Additional identification photos and seasonal range maps are available through Cornell Lab’s All About Birds.
| Feature | Ring-billed Gull | Bonaparte’s Gull |
|---|---|---|
| Length | About 18 inches (47 cm) | 11 to 15 inches (28-38 cm) |
| Bill | Yellow with a black ring | Thin and black |
| Legs | Yellow | Red (breeding), pink (nonbreeding) |
| Nesting site | Ground scrape on small islands | Stick nest built in trees |
| Typical breeding range | Southern Canada and northern US | Boreal forests of Alaska and Canada |
| Diet | Omnivorous, including garbage | Small fish and invertebrates |
The most telling difference between the two, at least for anyone scanning a Hawaiian beach, comes down to size and bill shape. A bulky bird with a thick yellow-and-black bill points toward a ring-billed gull, while anything smaller and more delicate with a thin black bill deserves a second look for Bonaparte’s gull, though the latter remains far rarer in the islands.
Neither species compares in scale to the seabirds that do call Hawaii home for part of the year. Frigatebirds and albatrosses dwarf both gull species and are a far more common sight along Hawaiian coastlines; readers interested in that size contrast can browse this list of the biggest flying birds in the world. Speed is another point of comparison worth exploring, since gulls are agile fliers built for quick maneuvering rather than raw velocity, a subject covered in this guide to the fastest birds.
Important Note: Reported gull sightings in Hawaii should always be treated with some skepticism unless documented with photos submitted to a recognized birding database. Misidentification with native seabirds like the white tern or black-footed albatross is common among visitors unfamiliar with Hawaiian wildlife.
For anyone hoping to actually witness one of these rare visitors, patience and timing matter more than location. Vagrant gulls tend to appear after major Pacific storm systems or during periods of unusual weather, when birds get pushed well outside their normal flight paths. Checking regional rare-bird alerts and following established Hawaiian birding communities remains the most reliable way to hear about a sighting before it moves on, according to observations compiled by the Hawaii Bird Guide.
Gulls in Hawaii will likely remain a rare curiosity rather than a common sight, and that scarcity is exactly what makes each documented ring-billed or Bonaparte’s gull sighting worth paying attention to. The islands’ isolation that keeps gulls away is the same isolation responsible for the unique, endemic bird life found nowhere else on Earth, according to research on the region’s geographic barriers cited by LifeOutOfTheBox.
