origin unknown
The first known use of godwit was in the 15th century
1 But tagging studies have demonstrated also that the godwit seems to have a knack of picking the optimum moment whenever it does arise.
2 Adults and larvae of these flies have been found in the stomachs of the dowitcher, the pectoral sandpiper, the hudsonian godwit, and the killdeer.
3 And then in May, the godwit undertakes a 6,000km trip to western Alaska to breed and nest, before returning directly to New Zealand across the Pacific in August/September.
4 Distances vary, but all told, in a year, the godwits cover some 30,000 kilometers, or nearly 18,720 miles, because they take a less direct route to return north in March.
5 But Mr Douglas has been wondering how the godwit might fare in a changed climate that also alters wind patterns in the Pacific.
6 The marbled godwit, or marlin as it is also called, is one of the largest birds of the Scolopacidæ family.
7 The epic odyssey that those transmitters recorded spurred Mr. Gill and other researchers to gather more data, both on bar-tailed godwits and other species.
8 This leads to the godwit taking on an enormous fat store before setting out on its marathons.
9 Incredibly, it is possible that three-month-old godwit juveniles fly their nonstop maiden voyage without adult supervision.
10 There should be no difficulty in distinguishing the godwit from any of the other shore birds, its long upward curved bill and brownish-barred back being features by which it may always be known.
11 Bar-tailed godwits in Russia have recently been documented flying at altitudes of three to four miles above ground.
12 Martha’s Vineyard: Nineteen snow geese at the Vineyard Golf Club in Edgartown, a marbled godwit at Eel Pond in Edgartown, and a blue-gray gnatcatcher on Clay Pit Road at Aquinnah.
13 In tidal mudflats, species such as the bar-tailed godwit - the larger birds in the photo above - refuel on worms and molluscs.
14 At Richmond Pond in Acoaxet, a Hudsonian godwit and three soras at Egypt Lane in Fairhaven.
15 The godwits probably rely on several cues for navigation, especially the sun and stars.
16 In 2007 scientists recorded a godwit flying more than 7, 000 miles (11, 500 kilometers), from Alaska to New Zealand, in nine days at an average speed of about 35 miles an hour (56 kilometers an hour).
2007年,科学家们记录了一只黑尾豫在九天之内以平均每小时35英里(56千米)的速度从阿拉斯加飞到了新西兰,飞行里程超过7000英里(11500千米)。
17 Martha’s Vineyard: a Black skimmer at Sarson’s Island, 2 Common ravens at Menemsha, and a White-eyed vireo. Nantucket: a rare western Cassin’s kingbird – one of fewer than five previous state records – in addition to a migrant Hudsonian godwit at Sesachacha Pond.
18 Frightful looked down on black ducks, mallards, bluewinged teals, plovers, godwits, yellowlegs, sandpipers—all the migrating birds that loved wetlands.
19 The godwit’s epic flight — the longest nonstop migration of a land bird in the world — lasts from eight to 10 days and nights through pounding rain, high winds and other perils.
20 It somewhat resembles the godwit in coloring, but it is more of a grayish tinge.
