This is an example of sequential tool use, which represents a higher cognitive function compared to many other forms of tool use and is the first time this has been observed in non-trained animals. Tool use has been observed in a non-foraging context, providing the first report of multi-context tool use in birds.
Tool use by animals is a phenomenon in which an animal uses any kind of tool in order to achieve a goal such as acquiring food and water, grooming, defense, communication, recreation or construction. [42] Originally thought to be a skill possessed only by humans, some tool use requires a sophisticated level of cognition. [43]
Captive bolt stunners are safer to use for operators in most red meat slaughter situations. There is no danger of ricochet or over-penetration as there is with regular firearms. The cartridges typically use 2 to 3 grains (130 to 190 mg) of smokeless powder but can use up to 7 grains (450 mg) in the case of large animals, such as bulls. The ...
More broadly, the researchers argue, tracking wildlife is important in understanding the unpredictable ways animals adapt to that changing planet — and a vital tool for ecology in the future ...

Among tool using otters, up to 21% of the day can be spent engaging in tool use. [10] In a study conducted from Alaska to Southern California, sixteen otter populations demonstrated that individual diet specializations are much more likely to be present in environments of rocky habitat over soft sediment substrates.

Bone awl. In archaeology, bone tools have been documented from the advent of Homo sapiens and are also known from Homo neanderthalensis contexts or even earlier. Bone has been used for making tools by virtually all hunter-gatherer societies, even when other materials were readily available.
Although tool use was long assumed to be a uniquely human trait, there is now much evidence that many animals use tools, including mammals, birds, fish, cephalopods and insects. Discussions of tool use often involve a debate about what constitutes a "tool", and they often consider the relation of tool use to the animal's intelligence and brain ...
