Numerous broken shells of a rare endemic snail Placostylus fibratus, a species rated as vulnerable, were scattered around rocky beds of dry creeks in rainforest of New Caledonian. We set a video camera near one site to identify the predator. We recorded a New Caledonian crow Corvus moneduloides dropping and consuming the snail. This is the first direct evidence of the crow dropping of this native species. The assumed weight of snails relative to the crow is exceptionally heavy among prey… Expand

Figures from this paper

New Caledonian crows infer the weight of objects from observing their movements in a breeze
The results suggest that birds used pre-existing knowledge about the behaviour exhibited by differently weighted objects in the wind to infer their weight, using this information to guide their choices. Expand
On the origins of physical cognition in corvids
Physical cognition involves a host of cognitive abilities that enable understanding and manipulation of the physical world. Corvids, the bird family that includes crows, ravens and jays, are renownedExpand
Complex Avian Behaviour and Cognition: A Mapping Sentence Approach
This chapter considers how mapping sentences and facet theory may be used to understand complex avian cognitive behaviour when it is thought of in this sophisticated sense. Expand


A review of the ecology and conservation of Placostylus ( Mollusca : Gastropoda : Bulimulidae ) in New Caledonia
Land snails of the genus Placostylus Beck, 1837 are found only in the Western Pacific, from the Melanesian Plateau to New Zealand. While the ecology of the New Zealand Placostylus species isExpand
Shell-Dropping Behavior of Western Gulls (Larus occidentalis)
-Westem Gulls (Larus occidentalis) at Bodega Bay, California drop shelled prey items to break them. I presented Washington clams (Saxidomus nuttalli) of known weight to free-flying gulls toExpand
New Caledonian Crows drop candle-nuts onto rock from communally used forks on branches
New behaviour associated with animals dropping objects from a height is reported: the placing of objects on a substrate to release them, and the repeated dropping of objects from the same release position in three-dimensional space by the use of forks in branches. Expand
Avian prey-dropping behavior. II. American crows and walnuts
American crows forage in this way on two species of walnuts in central California, USA, and adjusted the height from which they dropped nuts in ways that decreased the likelihood of kleptoparasitism and increased the energy obtained from each nut. Expand
The social structure of New Caledonian crows
New Caledonian (NC) crows, Corvus moneduloides, have impressive tool-manufacturing and tool-using skills in the wild, and captive birds have displayed exceptional cognitive abilities in experimentalExpand
Selection and Dropping of Whelks By Northwestern Crows
Prey selection, dropping behaviour and dropping site selection was investigated in Northwestern crows (Corvus caurinus) feeding on whelks (Thais lamellosa). Crows selected only the largest whelksExpand
Shell Dropping: Decision-Making and Optimal Foraging in Northwestern Crows
Decision-making and optimal foraging was investigated in Northwestern crows feeding on whelks (Corvus caurinus) and foraging efficiency was close to the maximum value attainable for crows. 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
Avian prey-dropping behavior. I. The effects of prey characteristics and prey loss
This paper presents the first theoretical framework for avian prey-dropping systems that incorporates the diversity of prey characteristics and social situations, and results indicated that quantitative and qualitative differences in item breakability and potential kleptoparasitism should have a significant effect on the height and pattern of prey dropping.

Evidence that crows have diversified and cumulatively changed the design of their pandanus tools is presented, suggesting that pandanus Tools have gone through a process of cumulative change from a common historical origin. Expand
