A decorated egg with a bird on it, given to a young married couple, is a wish for children.

Dr William Bird suggests in his study that wild places may induce impulsive behaviour in people.

Learn five species of bird, five butterflies, five trees, five bird songs.

Bird lovers, both young and old, have already responded with excitement at the news.

Some fly very long distances, including one kind of bird that flies from the remote north of the world, all the way to the distant south.

The birds will be encouraged to clean the park through the use of a small box that delivers a small amount of bird food.

Writing in the journal, the scientists describe how the storks from Germany were clearly affected by the presence of waste sites, with four out of six birds that survived for at least five months overwintering on rubbish dumps in northern Morocco, instead of migrating to the Sahel.

While many birds travelled along well-known routes to warmer climates, others stopped short and spent the winter on landfills, feeding on food waste, and the multitudes of insects that thrive on the dumps.

They have seriously polluted the places where birds spend winter.

They have led some birds to give up on migration.

They have changed the previous migration habits of certain birds.

The birds can easily eat pieces of plastic or rubber hands and they can die, said Flack.

Migrating birds affect ecosystems both at home and at their winter destinations, and disrupting the traditional routes could have unexpected side effects.

Landfill sites on the Iberian Peninsula have long attracted local white storks, but all of the Spanish birds tagged in the study flew across the Sahara Desert to the western Sahel.

In the short-term, the birds seem to benefit from overwintering ( ' , 过冬) on rubbish dumps.

For the birds, it's a very convenient way to get food.

Andrea Flack of the Max Planck Institute found that birds following traditional migration routes were more likely to die than German storks that flew only as far as northern Morocco, and spent the winter there on rubbish dumps.

Way up north in the Canadian Arctic, seabirds are picking up dangerous chemicals in the ocean and delivering them to ponds near where the birds live.

Some 10,000 pairs of the birds, called fulmars, a kind of Arctic seabird, make their nests on Devon Island, north at the Arctic circle.

People who live, hunt or fish near bird coloniesneed to be careful, the researchers say, The birds don’t mean to cause harm, but the chemicals they carry can cause major problems.

Other birds unknowingly carry seeds that cling to them for the ride.

In ponds closest to the colony, the result showed there were far more pollutants than the ponds less affected by the birds.

Canadian scientists have found a worrisome new example of the power that birds have to spread stuff around.

Birds flock together, fish school together, cattle herd together.

He captures birds only to let them go when he realizes the cruelty involved.

The bird Clark's nutcracker, for example, hides up to 100, 000 seeds per year, up to 30 kilometers away from the seed source, and has a very close symbiotic(共生的) relationship with several pine species, most 32 notably the whitebark pine.
