When building a nest, previous experience raising chicks will influence the choices birds make, according to a new study by University of Alberta scientists. The results show that birds that have ...

In a neat experiment on bird interior design, researchers show that finches conceal their nests by deliberately choosing construction materials that blend in with the background of the nest site. The ...

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 ...

Some of the small, plain songbirds known as Darwin’s finches might protect their young from flesh-eating parasites just by staying in the nest 1. The team found fewer larvae in the nests in which ...

A tiny bird, the Glacier Finch, thrives in the Andes mountains. It builds nests directly on glaciers, a unique survival strategy. This behaviour offers protection from predators and helps regulate ...

A new study suggests that some birds prioritize social information over visual evidence when making breeding choices. A new study in The Auk: Ornithological Advances suggests that some birds ...

When we think of glaciers, polar bears and penguins often come to mind. Finches are more associated with backyards than icy ledges, but one species found a way to survive one of Earth’s most extreme ...

WASHINGTON (Reuters) - Which nest is best to eliminate a blood-sucking pest? Scientists seeking to help endangered Galapagos Islands birds survive a deadly parasitic threat put that question to the ...

A new study led by UConn researchers gives hope that some populations of Darwin's finches may be better armed to survive a devastating invasive parasite. Credit: Sarah A. Knutie et al Scientists are ...

DEAR JOAN: I’m wondering if I should remove bird nests after they are no longer in use. I have house finches — I think — in the eaves of the porch. I know they often come back the next year, but do ...

Darwin's finches on the Galápagos Islands are once again providing insights into the theory of evolution, with two studies investigating their dealings with the parasitic avian vampire fly (Philornis ...
