Migratory Birds Disperse Seeds Long Distances

Some species of plants are capable of colonising new habitats thanks to birds that transport their seeds in their plumage or digestive tract. Until recently it was known that birds could do this over short distances, but a new study shows that they are also capable of dispersing them over more than 300 kilometres. Read […]

Wetland loss, Development Put Kashmir Bird Migration at Risk

SRINAGAR, India (AP) — The cackle and cry of Kashmir’s annual bird migration has long been a welcome ruckus for those living in the Indian-controlled Himalayan territory.

Wind Industry Plans Serious Changes to Protect Bats

Migratory bats, for some reason, have a lethal attraction to wind turbines. Now, they may get help via “feathering.” New industry guidelines, to be announced Thursday, aim to save tens of thousands of bats each year by idling turbines at low wind speeds during peak bat migration season. They could reduce by a third the […]
