New Caledonian crows are one of the few species that make and use tools in the wild. Tool types differ across their range in an overlapping pattern, suggesting that tool designs are copied with a high fidelity and may be transmitted across generations, thus allowing for cumulative changes to occur to the lineage of each tool type over time (cumulative technological culture hypothesis). However, little is known about how these crows learn to make such tools, how this information is transmitted to others, or what they know about the problems they solve. I present results from two experiments on wild-caught New Caledonian crows examining what information observers attend to, how social information is transmitted among juveniles and adults, and whether they attend to causal information when solving foraging problems.
