Laboratory-raised Northeirn blue jays (Cyanocitta cristata) have been observed tearing pieces from pages of newspaper and utilizing them as tools to rake in food pellets which were otherwise out of reach. The frequency of this behavior was dependenit upon the motivational state of the jay and the presence of food pellets. 

Topics from this paper

Tool use in captive crows
Four common crows were trained to peck a key for food reward and showed innovative behavior, in that they persistently wedged the tool between the edge of the response panel and the key, so that it acted as a lever. Expand
Manufacture and use of hook-tools by New Caledonian crows
TOOL behaviour in wild birds has been described as mostly stereotyped1,2, and tool manufacture involves little modification of material3–5. Here I report in New Caledonian crows Corvus moneduloidesExpand
Idle Lobster Traps Kill Blue Jays
Abstract We report observations of Blue Jay (Cyanocitta cristata) mortality in idle lobster traps stored on Merepoint Neck in the Town of Brunswick, Maine. Three of nine individual Blue Jays foundExpand
Corvids Using Objects to Displace Gulls from Nests
Two observations of corvids, a Fish Crow (Corvus ossifragus) and a Common Raven (C. corax), attempting to displace nesting gulls by using objects are reported. Expand

What a parrot's mind adds to play: the urge to produce novelty fosters tool use acquisition in kea.
Motivational and cognitive aspects of spontaneous tool-use acquisition in species that do not do so habitually, remain an open but most relevant question. To address this, we studied captive keaExpand
Insightful problem solving and creative tool modification by captive nontool-using rooks
It is shown that rooks, a species that does not use tools in the wild appears to possess an understanding of tools rivaling habitual tool users such as New Caledonian crows and chimpanzees, suggesting that the ability to represent tools may be a domain-general cognitive capacity rather than an adaptive specialization. Expand
Do woodpecker finches acquire tool-use by social learning?
The results suggest that tool–use behaviour depends on a very specific learning disposition that involves trial–and–error learning during a sensitive phase early in ontogeny. Expand
Tools and brains in birds
It is shown that relative size of the neostriatum and whole brain distinguish the true and borderline categories in birds using tools to obtain food or water and that the complex cognitive processes involved in tool use may have repeatedly co-evolved with large brains in several orders of birds.

Key pecking for food was shaped in four crows within a conventional operant-conditioning test chamber and the behavior of two crows was shaped so that they approached the matchsticks, picked one up in their beaks, approached the response key with the matchstick in theirBeak, and finally operated the responseKey by poking the match Stick through the screen.

Use of Tools by the Egyptian Vulture, Neophron percnopterus
THE use of natural objects as tools by free-living vertebrates has, so far as we know, been reported for four species only—the chimpanzee, Pan troglodytes; the gorilla, Gorilla gorilla; theExpand
