| 1. Picture this: You're hungry, and you need to go look for some food. Your favourite food is worms, and you know there are some in easy reach – but you can't see them because they're hiding. What do you do? If you're a Bassian thrush, you fart at them. According to Janey Levy's book “Really Strange Birds” these birds have adapted their foraging techniques to rely in part on generating enough gas to startle earthworms into moving. If the worms move, then the birds can find and eat them. | |
| 2. With a wingspan of up to 2.90 m, seen from far away, California Condors are sometimes mistaken for small aircrafts. | |
| 3. Native to the Amazon, hoatzin babies have tiny claws on their wings – as well as on their feet. Since their nests are in trees that frequently overhang water, it's a safety feature for when predators try to eat the babies. Baby hoatzins can simply hop down into the water, then climb back up the tree when it's safe. The wing claws disappear as the birds mature – once they can fly, they no longer need them. | |
| 4. The bearded vulture's (bārdainais grifs) diet consists of 70 to 90% bone, and it is the only bird in the world whose diet is like this, according to the World Wildlife Federation. It bashes larger bones into smaller, more manageable pieces by dropping them from a height so they shatter, and then eats the marrow and bone fragments on the ground. | |
| 5. Pigeons can recognize human faces. And not only that, but they can also use touch screens – and apparently even learn to read. In a paper published in the Proceedings of the National Academy of Sciences, scientists established that pigeons can learn to recognize around 50 words – and crucially, that they can distinguish words from non-words. |
