New Zealand study reveals secret long-distance travel of penguins
Source: Xinhua&&
WELLINGTON, Aug. 12 (Xinhua) -- Penguins might be flightless, but they still manage to swim thousands of kilometers every winter, New Zealand scientists said Friday.
Tracking of almost 100 penguins in the Southern Ocean revealed the secret of where they went over the dark Antarctic winter, said researchers with the government's National Institute of Water and Atmospheric Research (NIWA).
Tags on the sub-Antarctic rockhopper and Snares penguins showed they travelled more than 15,000 kilometers at sea between April and October each year, said NIWA seabird ecologist Dr David Thompson.
"If they are constantly moving, this averages out at about 100 km a day, but you also have to add on to that the distances covered vertically as the birds dive to capture food," Thompson said in a statement.
The tagging program targeted rockhopper penguins at Campbell Island and Snares crested penguins, endemic to Snares Island.
While the Snares penguin population was relatively stable, rockhoppers at Campbell Island had declined by at least 21 percent since 1984, leaving just over 33,000 breeding pairs on the island.
The island was once the world's largest breeding colony of rockhoppers, the smallest of all penguin species, but between 1942 and 1984 the population dropped by about 94 percent.
It was not known what caused such a sharp decrease, but one theory was that changes in the penguins' diet might be responsible.
Thompson said they had "an extreme lifestyle."
"They come to land to breed and when they finish that, go back out to sea where they feed up for a month. Then they come back to land to sit and moult their feathers. During that period they don't eat at all," he said.
"Having basically starved themselves, they go back out to sea in poor condition. They've grown a whole new set of feathers so their plumage is fantastic, but it's quite demanding so they're really scrawny," said Thompson.
"We think winter is pretty important and that there is almost certainly something going on in the ocean causing the population to decline."
The Snares penguin headed exclusively west towards Australia, while the rockhoppers went east and covered a wider section of the ocean.
"We don't know what they're feeding on when they' we don't know if the amount of food available was more or less comparable to five or 10 years ago so this is very preliminary," said Thompson.
He planned to repeat the project and include other species, such as the erect crested penguin of the Antipodes Islands.
"The extra species will give us more information on how they relate to each other when they go away. It may be that they use different space, or it may be that populations of different islands get together at sea," he said.
"Prior to this study, we didn't have a clue where rockhoppers went in the winter, but the spaces they use in the ocean might be really important -- not only for them, but for scientists to better understand what is causing the population decline."

Please enable JavaScript to use all the features on this page., April 2011, Pages 840-844Gillnet fisheries as a major mortality factor of Magellanic penguins in wintering areasShow moreAbstractThe incidental capture in fisheries is probably the main conservation problem affecting seabirds. While the capture of albatrosses and petrels on longline hooks is well-known worldwide, the bycatch of diving seabirds in gillnets is an overlooked conservation problem. During a winter coastal fishing trip, the capture of Magellanic penguins (Spheniscus magellanicus) was recorded in driftnet and bottom setnet fisheries for the first time in southern Brazil. The highest captures rates were found in driftnets, from 146.5 to 545.5 penguins/km2 of net and a total of 56 dead penguins were recorded. In the bottom gillnet, a total of 12 birds were killed and the capture rates varied from 41.7 to 125.0 penguins/km2 of net. Although preliminary, the results presented in this paper were consistent between sets. If we consider the magnitude of driftnet and setnet fishing fleets, and that most dead penguins were adults, the impact upon Magellanic penguin populations is probably significant.Research highlights? Bycatch of diving seabirds in gillnets is an overlooked conservation problem. ? We recorded for the first time in Brazil incidental catches of Magellanic penguins. ? Capture rates occurred in both bottom and driftnet fisheries. ? A total of 68 penguins were killed in 16 sets. ?

&& There are roads and highways in every part of our country. They go up mountains, through valleys, and over rivers. In the summer, these roads can take you whenever you want to go. But in the winter, many roads must be kept clear of snow or they cannot take you anywhere. && The men who work on roads work hardest in cold weather. They must clean up the snow from the streets and highways, from roads and sidewalks. Airport runways and railways must be kept clear all the time. Large snowplows(扫雪机) are used to clear roads. They push the snow off the road and over to the side. Next time you travel in the winter time, think of the men who help you. They keep the roads and highways clear, so you can go where you want. 根据短文，回答问题 1 In winter what do the road workers work for? & &&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&& 2 Do the workers build the roads only for the airport? & &&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&& 3 what machines can clean up snow on the roads easily? & &&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&& 4 Where must snow be pushed? & &&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&& 5 Why can you take an easy trip in the winter time? & &&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&. &&&
