Corvids are known for their cognitive flexibility, and many have innovated various forms of
tool use. Here, we review tool use and tooling in common ravens (Corvus corax) and …

Play behaviour and tool using in birds, two well-delineated and amply researched
behaviours, have generally been associated with cognitive abilities. In this study, these …

Background There has been a long history of anecdotal reports in the field of natural history
and comparative (evolutionary) animal behavior. Although, at the time of writing there is an …

Tooling is associated with complex cognitive abilities, occurring most regularly in large-
brained mammals and birds. Among birds, self-care tooling is seemingly rare in the wild …

Comparative analysis of higher cognitive abilities in animals provides for assessment of the
evolutionary underpinnings of the formation of human thought and language. This review …

A recent article by Fayet et al.(1) reports two observations of wild puffins (Fratercula arctica)
from two geographical locations touching different body parts with a stick. The behaviors are …

Recent reports on tool use in nonforaging contexts have led researchers to reconsider the
proximate drivers of instrumental object manipulation. In this study, we explore the …

Tool use is taxonomically associated with high behavioural flexibility and innovativeness,
and its prevalence is greater in primates and some bird species. This association, however …

Tool use is a central topic in research on cognitive evolution and behavioral ecology in non-
human animals. Originally thought to be a uniquely human phenomenon, many other …

Tool use by animals, traditionally studied mainly in captive primates due to its relevance to
human evolution, has been investigated in both free-ranging and captive mammals. Here, I …
