Male collared flycatcher, singing for multiple females.
Biologists investigated whether birds that search for multiple mates would evolve ever more elaborate songs to attract them. What they found might have surprised Darwin.

The birds follow a few simple rules to create complex patterns.

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.
Success with conservation of Kangaroo Island’s Glossy Black-Cockatoos can now be compared with other bird conservation efforts around the country.
New research has shown how to measure conservation progress for Australia's 238 endangered bird species

Even when birds are not flying in a flock, they may observe each other to sense the world around them.

A new type of Archaeopteryx fossil helps build the case for this creature being called 'the first bird'.
The composition of black and white in a magpie’s poo differs between species. Some splatter more of the uric acid (white), some have more black (indigestible solids). It depends on their diet.
Like reptiles, birds do not have two separate exits from the body. They have one, called the cloaca. It is quite similar to the human anus but the cloaca expels both indigestible bits and toxins.
On the fence.
As both beneficiary and victim of EU policies, yellowhammers are apt symbols for Brexit's divisions.
The majestic White Ibis.
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?

Today, we're hearing about a researcher who records birdsong, how tech changes music and why song might help address Indigenous language loss.
Birds don’t fly across wide Amazonian rivers like the Rio Negro.

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.
