In the forests of Brazil lives a moth that drinks tears of birds. It perches quietly at the back of an antbird at night – when the bird’s not very active – and uses its long, flexible proboscis to lap up its tears. Don’t believe me? See for yourself!
I have a new video story up at Science magazine about an amazing moth caterpillar that fights off things that try to eat it, including beetles that are called ‘caterpillar hunters’. Check it out, folks!
The accompanying short story is available to read here.
Animals struggle during winters. No surprise there. But it isn’t a shortage of food alone that bothers them. This January was pretty harsh with temperatures lingering below zero for days on end and that meant ice was everywhere. Even the city lakes were covered in ice. When it comes to birds, you may think “that’s no problem, they can fly.” But icy conditions made it really hard for some. From the antics that played out on the ice, it seemed highly sensible of these swans to break their way through the ice than to walk over it or take off on the slippery runway:
The blue-capped cordon-bleu (Uraeginthus cyanocephalus) has a special talent. Not only can it sing, it can shake a leg or two. For its courtship display, it holds a piece of nesting material in its beak, points its head upward, moves up and down, and sings. Both males and females bob and sing like this, and choose their partner…
Study explains how wandering ants guide a group of food gatherers back to the nest.
When out of their nest, workers of the longhorn crazy ant (Paratrechina longicornis) band together toward a common goal: to bring food back to the nest. But even when a few of these long-legged, silver-haired ants (of Ant-Man fame) team up to carry a large item—such as a wasp—they often lose their way home.
