Galapagos finches caught in act of becoming new species


A population of finches on the Galapagos has been discovered in the process of becoming a new species.

This is the first example of speciation that scientists have been able to observe directly in the field.

Researchers followed the entire population of finches on a tiny Galapagos island called Daphne Major, for many years, and so they were able to watch the speciation in progress.

Bird of prey returning to Denmark in numbers


The population of red kites is taking off in Denmark, with at least 200 breeding pairs of the bird of prey now present in the country’s natural areas.

The Danish Ornithological Society (Dansk Ornitologisk Forening, DOF) has estimated that number will as much as double in coming years.

A limited number of areas across the country, including south-eastern Jutland, Funen, Bornholm and northern Jutland, are considered the current prime spots for the species.

But the growing red kite population is showing signs of spreading to other western and northern habitats, according to ornithologist Per Rasmussen, who has collected data on the animal.

In the study, published Friday in the journal Scientific Reports, paleontologists identify two different ancient birds, Gastornis and Presbyornis. Of the two birds, Gastornis is (literally) the bigger discovery.

Only 500 years ago a giant flightless bird species called the Moa lived on New Zealand.

There have been claims over the years since its extinction that there are still Moa's living there but nothing has really ever went beyond supposed sightings by people.

Hypnotizing video captures thousands of starlings zigzagging as hungry falcon attacks


Starlings are known to flock together into mesmerizing groups called “murmurations,” and then swoop and dive together in synchronized acrobatics shows.

But this group of starlings — part of a murmuration of as many as 10,000 that has gathered in West Cork, Ireland — started doing particularly impressive aerial tricks earlier this month. It was caught on video by a group of local birdwatchers, too.

These tropical hummingbirds make cricket-like sounds other birds can't hear


Researchers have found that a tropical species of hummingbird called a black jacobin makes vocal sounds with an unusually high-frequency pitch that falls outside birds' normal hearing range. It's not yet clear whether the hummingbirds can even hear themselves, the researchers say.
