Hummingbirds are 325 species of tiny, colourful, tropical birds which sip nectar from flowers.
Hummingbirds are the most amazing aerial acrobats, hovering and twisting i ii front of flowers.
The bee hummingbird is the world’s smallest bird – including its long bill, i measures just 5 cm.
To hover, horned sungem hummingbirds beat their wings 90 times per second.
Hummingbirds have long bills to suck nectar from flowers.
Swifts and hummingbirds are on the wing so much that their feet have become weak – which is why they are called Apodiformes, meaning ‘footless ones’.
Swifts are among the fastest flying birds. Spine-tailed swifts of eastern Asia have been recorded at 240 km/h.
Swifts use their short, gaping bills to catch insects on the wing.
Swifts may fly through the night without landing. They may even sleep on the wing. European swifts fly all the way to Africa and back without stopping.
When swifts land, they cling to vertical surfaces such as walls, cliffs and trees.
Swifts winter in Africa, then fly north and east to Europe and Asia to breed. Their feet are so small and weak that they can hardly perch on twigs. Great dusky swifts nest and roost behind waterfalls, and have to fly through the water to exit their nests
