Few people have the tenacity of ecologists Peter and Rosemary Grant, willing to spend part of each year since 1973 in a tent on a tiny, barren volcanic island in the Galapagos. Even fewer would have ...
Carotenoids are the underlying pigment for much of the enormous variety of color found across birds and form the basis for the colors red, yellow and orange. In a study published in Current Biology, ...
The 14 species of Galapagos finches that have inspired evolutionists since the days of Charles Darwin may reveal yet more. The birds may have evolved different courtship songs as byproducts of beak ...
Invasive parasites in the Galápagos Islands may leave some Darwin’s tree finches singing the blues. The nonnative Philornis downsi fly infests the birds’ nests and lays its eggs there. Fly larvae ...
Galápagos finches use their beaks to crush seeds and sing songs, so what happens to their musical trills when their beaks change to respond to new menus available under drought? Jeffrey Podos and ...
Charles Darwin developed the theory of evolution by observing finches on the Galapagos Islands and speculating how each type developed distinct characteristics to take advantage of local conditions.
Darwin's finches are among the most celebrated examples of adaptive radiation in the evolution of modern vertebrates and now a new study has provided fresh insights into their rapid development and ...
DEAR JOAN: A female house finch, I believe, that has been visiting our backyard feeders for several days in a row has a very deformed beak. It appears that her lower beak is grossly long and her upper ...
Biologist have compared the genes of large-beaked Cameroonian finches to those of their smaller-beaked counterparts, found the answer to a 20-year old mystery: 300,000 base pairs, apparently inherited ...
