Keeping urban habitats such as parks neat and tidy by removing dead wood and leaves is driving the species which live there to extinction.
Robins are a much loved Christmas icon, but wind turbines installed in their habitat are affecting their song, with worrying consequences.
Do you know this downy woodpecker?
By looking closely at traits like wing feathers and spot patterns, a computer scientist trained an algorithm to recognize individual woodpeckers.
A pink pigeon in the wild of Mauritius.
Pink pigeons may make more charismatic subjects for our adoration, but their feral relatives who keep us company in towns and cities are just as deserving.
Generations of giraffes.
It can actually be very tricky to define a species, but in the 1900s, scientists found a pretty good way.

The ibis has become an Australian cultural phenomenon. The birds' tenacity and fearlessness as environmental refugees mean they attract love and hate alike.
Not all birds have eyes on the sides of their heads – but even those that do can see straight in front of them.
Could music one day be something we experience through augmented reality, responding to the way we move through the world? Sound supplemented with colours and shapes?

Rivers are natural boundaries for evolving populations. But scientists don't agree whether they create new species or just help maintain them. Research using birds' molecular clocks provides some answers.
Both male and female birds sing to impress other birds, but as well as that, they do it for pleasure!
The Canada jay recently had its name restored, but Canada still doesn’t have a national bird.
Until very recently the Canada jay was called the gray jay. How did the bird lose its original name in the 1950s, and gain it back again, just in time for Canada Day?
London should be one giant pigeon cemetery, but you rarely see the bodies.
