BioMed Central What lures a lady frog to her lover? Good looks, the sound of his voice, the size of his pad or none of the above? After weighing up their options, female strawberry poison frogs (Oophaga pumilio) bag the closest crooner they can, finds research in BioMed Central's open access journal Frontiers of Zoology.

Scientists discover unusual alliances in leks, or groups of males Leks, they're called, gatherings of males of certain animal species for competitive mating displays. But not every lek's members are competitors, scientists have learned. Some--birds called wire-tailed manakins, residents of tropical forests in the Americas--are cooperators as well as competitors. The research was funded by the National Science Foundation (NSF). "Male vertebrates often form reproductive coalitions to gain...

By John David Sutter, The Oklahoman Aug. 3--A plucky little bird in northwest Oklahoma -- known for its comical mating dances in which it patters around like a jittery wind-up toy -- has found itself pitted against an unlikely environmental foe. Huge power-generating wind turbines are expected to pop up all over the lesser prairie chicken's habitat in coming years, and biologists say the development could push the birds onto the endangered species list or even into extinction. "We're...

CHEYENNE, Wyo. (AP) - The federal government needs to impose new restrictions on oil and gas development in the West because current policies are failing to protect sage grouse, according to conservationists citing a new study of the birds in western Wyoming. With all the oil and gas development going on now and planned in the future, "care really must be taken if we're going to have these wide open ecosystems in the future," Erik Molvar, a wildlife biologist with the Biodiversity...

The Ruff (Philomachus pugnax), is a medium-sized wading bird. It is usually considered the only member of its genus Philomachus, but more recent research indicates that the Broad-billed and Sharp-tailed Sandpiper may belong there too. Their breeding habitat is bogs, marshes and wet meadows with short vegetation in northern Europe and Russia. The Ruff is migratory, wintering in southern and Western Europe, Africa and India. They are highly gregarious, with a wintering flock of 1 million birds...
