1 . New Caledonian crows are well-known for using different types of tools for preying (捕食) from tree holes and other hiding places. While they firmly hold their tools in the bill, they need to put them down to eat. This is when crows are at risk of losing their tools by accidentally dropping them or having them stolen by other crows.

In an earlier study, researchers in the UK had discovered that crows keep their tools safe when not needed, using one of two “safekeeping” strategies—they either securely hold them trapped underfoot, or temporarily put them into a nearby hole or behind bark. But are crows more careful when handling particularly valuable tools?

“Many of us will fuss (大惊小怪) about a brand-new phone, making sure it does not get scratched, dropped or lost. But we may handle an old phone with a cracked screen quite carelessly,” said lead author Barbara Klump from the Max Planck Institute of Animal Behavior, Germany.

Crows at one of the team’s long-term study sites use two different kinds of stick tools: complex hooked tools and basic non-hooked tools. The former are painstakingly crafted from a relatively scarce plant species, while the latter are simply twigs (细枝) sourced from the forest floor. “Hooked tools are not only more costly to obtain, but they are also much more efficient,” explained Barbara Klump. “Depending on the foraging (觅食) task, crows can get prey with these tools up to ten times faster than with non-hooked tools.”

In their new study, the researchers now discovered that New Caledonian crows are more likely to keep valuable hooked tools safe between uses than the more basic non-hooked tools. “It was exciting to see crows are just a bit more careful with tools that are more efficient and more costly to replace. This suggests that they have some conception of the relative value’ of different tool types,” noted study co-author James St Clair.

This is the first study to investigate how animals handle and store tools of different kinds, providing a new way to measure how much they value these objects.

Have you wondered how your body knows when to wake up or why you need the toilet less at night? Influencing by light, body clocks use the sun to help your body to run on time.

Falling     1     the 15th day of the 8th lunar month, the traditional Chinese Mid-Autumn festival is all about the full moon and family reunion it represents.
