Gliding on extremely long, narrow wings, these largest of seabirds spend most of their lives at sea, alighting on the water when becalmed or when feeding on squid, fish and refuse. Rarely can they be seen from shore. Most species nest in large colonies on remote oceanic islands; pairs mate for life. In flight, feet and legs may not be visible.

These gull-size seabirds have longer wings than gulls; bill are topped with large nostril tubes. Rapid wingbeats alternating with stiff-winged glides present a distinctive flight pattern as these birds skim the waves in search of food. Pelagic; most species are rarely seen from shore.

Sprightly fliers, these small seabirds hover close to the water, pattering or hopping across the waves to pluck up small fish and plankton. Some species follow ships at night because the birds are attracted to strong lights similar to the behavior of moths which results in high mortality of some colonies. Identification is often difficult. Flight patterns may help to distinguish the various species, but flight can vary deceptively depending on weather.

Dabbling Ducks Surface-feeding members of the genus Anas: the familiar "puddle ducks" of freshwater shallows and, chiefly in winter, salt marshes. Dabblers feed by tipping tail-up to reach aquatic plants, seeds, and snails. They require no running start to take off but spring directly into flight. Most species show a distinguishing swatch of bright colour, the speculum, on the secondaries. Many are known to hybridize. |

Pochards Diving ducks of the genus Aythya have legs far back and far apart, which makes walking awkward. Heavy bodies requires a running start on water for takeoff. Various species hybridize; seemingly rare birds sighted outside their normal range may in fact be hybrids. |
