however, and continued prodding about in the mud. When I had come within two steps of them, they raised their heads and waddled farther off among the hummocks, from where they peered out through drooping grass. All but the bright eyes and yellow bills blended completely with the surroundings. Matthews has well said that their pattern fits in so thoroughly with the environment that it is sometimes only the movement of the conspicuous yellow bill that calls one’s attention to their presence. Many observers have noted the birds’ preference to lose themselves in the grass when they are approached, rather than to seek safety in the air, and it is likely that before the arrival of men and guns at South Georgia they used their wings only for relatively short and infrequent flights.
44: 320: 472:"The head is methodically withdrawn time and again for surveillance, but it is not unusual to see both giant petrels and pintails simultaneously picking at the same carcass. The ducks are so clever in maneuvering that not many are caught unaware. Unlike the giant petrels that acquire grisly scarlet heads while gorging on the bloody flesh, the fastidious pintails remain remarkably clean by dipping frequently into streams or pools of water." 511: 31: 367: 452: 565: 358:, a relatively recent self-introduction first recorded breeding on South Georgia in 1971. The speckled teal also has a yellow bill but differs in being smaller and more compact, with less spotting on the flanks, and having a buff bar in front of the speculum, a central white stripe on the underwing, and a shorter and less pointed tail. 470:"One might surmise that the delicate little pintails wait their turn to pick at the bones and small scraps left by the larger predators. Wrong assumption! As soon as there is a small opening in the seal carcass the ducks dive headlong into the hole, which conceals from view their bills and at times even their heads. 505:
Their speed was incredible, dashing from clump to clump like small rats, and it took considerable time to catch them. The parent meanwhile showed little concern, resting on a rock at the edge of the sea some 30 yards away. Their only natural enemy is the skua and time must have shown that so long as

Numbers have since recovered with the abandonment of South Georgia as a whaling base; the population probably exceeds 2,000 and is about as abundant as can be expected for the available habitat. The pintail was described in 1979 as being widespread in small numbers and frequenting most bays and

The back, breast and flanks are scalloped with buff; the underparts are buffy white, mottled with brown. The bill is yellow with a blue and black line on the 398:
On December 20th, 1912, I photographed a pair of teals feeding in a trickle of water which ran through tall tussock grass from the melting edge of a glacier. The birds were well hidden by the screen of grass, and I almost stumbled over them before seeing them. They appeared quite unconcerned,

The preferred habitat for raising broods is tussock-rimmed freshwater ponds where the chicks feed around the edges while the female stays in more open water. The broods are moved overland through the tussock from pond to pond. Niall Rankin, who led an expedition to South Georgia after the

The pintail is widely distributed along the north coast, and the western third of the south coast, of South Georgia, as well as on its offshore islands. It is largely absent from most of the south coast of the main island because of unfavourable topography.

Unlike other pintails, the males are similar in appearance to the females, though larger. The ducks are 45 to 65 cm in length, the males weighing 610 to 660 g, the females 460 to 610 g. Minor differences are that the male has uniformly brownish-grey
556:”Formerly this little duck was common throughout the coastal belt of the island, but as soon as whaling stations started to spring up and its flesh became appreciated the bird stood little chance of survival if it ventured near any of the populated 560:. Numbers have steadily decreased and while 40 years ago a flock of 100 teal was not an uncommon sight in the winter season, now it is unusual to see more than half a dozen together.

However, the number of rectrices in the ducks is variable, with many mainland pintails also having 16 rectrices and a few South Georgia pintails even having 18, and the three ducks are now usually 481:
South Georgia pintails breed in solitary pairs during a long breeding season from late October to early March. Their nests are frequently sited some distance away from water; they are well concealed in

I never discovered a nest with eggs, but found two ducklings on Albatross Island, about two days old, on December 18th, also another brood about a week old on March 11th.

Outside the breeding season, and when food is locally abundant, the ducks may congregate in small flocks, sometimes of up to about a hundred. Murphy noted:
