4. Swallow-Tailed Hummingbird

The swallow-tailed hummingbird (Eupetomena macroura) lives in east and central South America. It prefers semi-open areas, sparse woodland, coastal regions, and gardens, but will avoid dense rainforest. It has a long forked tail that comprises half of the bird's 16 cm length. Its plumage is a mixture of green, blue, and purple, and its wings flap at approximately 20 beats per second, allowing it to hover while feeding on flower nectar. They are aggressive towards other birds and will `dive-bomb' or pester birds as large as hawks!

3. Poison Dart Frog

The poison dart frog (pictured: Dendrobates azureus) lives in Central and South American rainforests, growing to between 1.5 and 6 cm in length. Indigenous people used the frog's toxic secretions to poison the tips of blow-darts, giving the frog its name. The secretions, which are being studied in medical trials, might also be used as muscle relaxants, appetite suppressants, and heart stimulants. Their bright colors form `aposematic patterns', which serve to ward off predators by suggesting an unpalatable toxicity. There are around 175 closely related species of poison dart frog which vary in size and coloration. The most colorful are the 5 within the dendrobates genus.
