There are hundreds of variations on the basic 'flavour' of bird migration.
Migrating to Europe changed the immune systems of birds who no longer needed to worry about African diseases.
The male cardinal tenderly feeding his mate is just one example of the hard work wild animals undertake in springtime. That work often benefits humans.
Wild animals are hard at work this spring. Here's how their hard labour benefits humans, and why we should be more appreciative.

City living isn't for everyone, but certain birds can prosper in the environment.
Tundra swans, which nest in the Arctic and migrate south in fall, alight at Mattamuskeet National Wildlife Refuge in North Carolina.
The Interior Department is narrowing protection for migratory birds to cover only deliberate harm such as hunting, but not threats like development or pollution that kill millions of birds yearly.

Birds can usually sense when they are not feeling well and like many other creatures, seem to seek out-of-the-way places to be alone.
A drone image of a breeding colony of Greater Crested Terns. Researchers used plastic bird decoys to replicate this species in an experiment that compared different ways of counting wildlife.
A few thousand fake ducks, a group of experienced wildlife spotters and a drone have proven the usefulness and accuracy of drones for wildlife monitoring.
A drying climate caused a mass extinction among plants, but paved the way for the ancestors of modern reptiles, mammals, and birds.
African penguins appear to move away from areas where seismic underwater surveys are happening.
Loud noise from underwater seismic surveys can drive penguins from their normal foraging grounds.

In our increasingly noisy world, how do you make sure that your voice is heard? If you’re a bird, that depends on the type of noise and what you’re trying to say.
Super-black feathers on these guys are like looking into a dark cave.

Crested pigeons make a rapid trilling sound when they take flight that can be used to warn others of danger. But what is it that makes the sound?
