Bats evolved diverse skull shapes due to echolocation, diet

University of Washington

In a paper published May 2 in Nature Communications, a University of Washington team reports that two major forces have shaped bat skulls over their evolutionary history -- echolocation and diet -- generating a huge diversity of skull shapes across more than 1,300 bat species today.

Newswise: What Drives Multiple Female Acorn Woodpeckers to Share a Nest?

What Drives Multiple Female Acorn Woodpeckers to Share a Nest?

Cornell University

Acorn Woodpeckers live in close-knit family groups and have one of the most complex breeding systems of any bird in the world. In about 20 percent of family groups, up to 3 related females may lay eggs in the same nest. They raise the chicks cooperatively with one or more related males. This behavior is known as joint nesting or “cooperative polyandry.” Only five other species of birds worldwide are known to do this. The reasons that may be driving the behavior are outlined in a study recently published in The American Naturalist.

Hybrid Species Could Prevent Darwin’s Finches Falling Prey to Invasive Parasite

Flinders University

A hybrid bird species on the Galapagos Islands could help scientists find a way to stop an invasive fly which is killing off the hatchlings of famous Darwin’s finches at an alarming rate, according to new research. 10 related species of the iconic Darwin’s finches are being threatened by the invasive fly Philornis downsi from South America, which lays its eggs into birds’ nests where the predators then hatch and devour defenceless chicks before the parents can react.

Vulture Species Coexist; Don't Compete for Resources

University of Georgia

The turkey vulture and the black vulture are able to coexist because their traits reduce the need for them to compete for nutritional resources.

Google Searches Reveal Popular Bird Species

Cornell University

Cross-referencing a decade of Google searches and citizen science observations, researchers have determined which of 621 North American bird species are currently the most popular and which characteristics of species drive human interest. Study findings have just been published in the Proceedings of the National Academy of Sciences.

Newswise: Scientists Use eBird Data to Propose Optimal Bird Conservation Plan

Scientists Use eBird Data to Propose Optimal Bird Conservation Plan

Cornell University

A new paper published today in the journal Nature Communications shows a blueprint for conserving enough habitat to protect the populations of almost one-third of the warblers, orioles, tanagers, and other birds that migrate among the Americas throughout the year. For the research, an international team of scientists used the Cornell Lab of Ornithology's global citizen science database, eBird, to calculate how to sufficiently conserve habitat across the Western Hemisphere for all the habitats these birds use throughout their annual cycle of breeding, migration, and overwintering. The study provides planners with guidance on the locations and amounts of land that must be conserved for 30 percent of the global populations for each of 117 Neotropical migratory bird species.

Got Bird Nests? Report to NestWatch!

Cornell University

Ithaca, NY—Around the world, birds are building nests and raising families—even near homes, offices, or in local parks. Anyone who finds a bird's nest can help scientists by reporting to the free NestWatch project at the Cornell Lab of Ornithology. NestWatch collects, analyzes, and distributes data, serving as a warehouse of nesting bird information. NestWatchers, in turn, get to witness the start of new life and help to preserve it with their valuable information.

Newswise: Birds’ surprising sound source

Article ID: 711085

Birds’ surprising sound source

University of Utah

Birds, although they have larynges, use a different organ to sing. Called a syrinx, it’s a uniquely avian feature. Now, a team that brings together physics, biology, computation and engineering finds that the syrinx confers an advantage: by sitting so low in the airway, the syrinx can produce sound with very high efficiency.

Study: Some Woodpeckers Imitate a Neighbor's Plumage

Cornell University

In the first global test of the idea, scientists have found evidence that some woodpeckers can evolve to look like another species of woodpecker in the same neighborhood.
