Darwin’s finches continue to inform and confuse

Charles Darwin’s famous Galápagos finches are once again helping us to understand the natural world. New research on these complex little birds demonstrates that our understanding of the genetic markers used to predict a species’ extinction is overly simplistic, a pressing problem at a time of unprecedented extinction rates around …

Parasites ruin some finches’ songs by chewing through the birds’ beaks

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 feast on the chicks’ blood and tissue, producing festering wounds and killing over half of the baby birds. Among …

Alert: Junk Food Is Harming Birds!

(MENAFN – The Costa Rica News) Better known as the ‘Darwin’s finches‘, it is the species of birds that, until now, most fe on food prepared for human consumption. This phenomenon occurs due to the increasing population and tourism in Costa Rica and, also, in latitudes outside of our country. …

Human activity can influence the gut microbiota of Darwin’s finches in the Galapagos

In the Galapagos Islands, Darwin’s finches drawn to junk food are experiencing changes in their gut microbiota and their body mass as compared to finches that don’t encounter human food, according to a new University of Connecticut study. The study of Darwin’s Finches, published today in Molecular Ecology, builds upon …

Human activity can influence the gut microbiota of Darwin’s finches in the Galapagos

The study of Darwin’s Finches, published today in Molecular Ecology, builds upon a study on the effects of human activity on finch diet in the same location, says Sarah Knutie, assistant professor of ecology and evolutionary biology at UConn. Researchers studied fecal samples and body mass data from female finches, …

Scientists Watched a New Bird Species Evolve on Galapagos in Just 2 Generations

Scientists in the Galápagos have observed something amazing: the evolution of a completely new species, in the wild, in real-time. And it took just two generations. Back in 2017, genomic sequencing and the analysis of physical characteristics officially confirmed the new species of Darwin’s finch, endemic to a small island …

On the Origin of Galápagos Finches – Island Conservation

Researchers have long wondered where Darwin’s Galápagos finches originated from and have identified a few possibilities, but conservationists face a different challenge in protecting the archipelago’s biodiversity. Galápagos finches are famous the world around as a prime example of the process of evolution and adaptive radiation. Long before finches inspired Darwin, they were …
