finches

In some finch species, the difference between colorful males and muted females comes down to one gene, BCO2, which encodes an enzyme that degrades carotenoids.

Gene activity is linked to songbirds’ tunes.

Scientists uncover a potential reason why redder house finches have better health.

Population reductions in species such as sparrows and blackbirds reflect a concerning pattern of declining biodiversity across the continent, researchers find.

By combining experimental data with computer models, researchers were able to predict a pathogen’s evolution toward more virulence.

Full genomes of Darwin’s Galápagos finches reveal a critical gene for beak shape and three overlooked species.

Darwin’s finches use pesticide-treated cotton to line their nests and unwittingly protect themselves against parasitic fly larvae.

Two species of songbirds pack their nests with scavenged cigarette butts that repel irksome parasites.

A round-up of recent discoveries in behavior research.
