"Warmer global temperatures aren't just wiping out the habitat of polar bears and penguins. They're also affecting many species closer to home -- including some right in your back yard. In this year's State of the Birds report, issued earlier this month, researchers from the National Audubon Society, U.S. Department of Interior, Cornell Lab or Ornithology, and others studied how climate change is affecting the habitats, ranges, and populations of birds across North America. OnEarth takes a look at eight vulnerable bird species from across the continent."

"New research indicates that the middle [of the food chain] -small insectivorous birds and lizards-are critically important to overall health of an ecosystem, and actually help promote greater biomass." "Gruner and a team of other researchers looked at more than 100 studies insect predation by birds, bats or lizards and found that, regardless of the predator in question, their presence was associated with a 40 percent reduction in damage to plants. In turn, a healthy population of insectivores was linked to a 14 percent increase in plant biomass."

Global climate change poses a significant threat to migratory bird populations, which are already stressed by the loss of habitat and environmental pollution, according to a report released Thursday.

A new species of bird, the spectacled flowerpecker, has been spotted in the rainforests of Borneo.

Highlights from the National Wildlife Federation Magazine Photo Contest in 2009, including tigers, fish, birds, rabbits and bugs.

Maps in the new Atlas of Global Conservation show the diversity of bird, animal and plant species populations, which are among 80 that scientists have produced for a comprehensive look at the planet's eco-regions. The maps crosses three types of habitats that exist: terrestrial, freshwater, and marine.

The seed dispersal activities of many animals is essential for the Amazon and other forests, because, as Anderson explains: "plants rely on the seed dispersal activities of these animals (i.e. birds, bats, monkeys, tapirs, rodents, and fish) to move seeds away from the mother tree to good sites for germination […] For pioneer species like Cecropia (a genus of tree that we studied), seeds might need light gaps to germinate-that is, seeds might have very specific requirements for germination."
