Corvid caching: Insights from a cognitive model.

Journal of Experimental Psychology: Animal Behavior Processes, 2011
Caching and recovery of food by corvids is well-studied, but some ambiguous results remain. To help clarify these, we built a computational cognitive model. It is inspired by similar models built for humans, and it assumes that memory strength depends on frequency and recency of use.

Corvid cognition

WIREs Cognitive Science, 2014
Numerous myths and legends across the world have suggested that corvids are intelligent. However, it is only in the last two decades that their cognition has become the subject of serious scientific investigation. Here I review what we currently know about the temporal, social, and physical cognition of this group.

Transmission dynamics of West Nile virus in mosquitoes and corvids and non-corvids

Journal of Mathematical Biology, 2013
There are more than 300 avian species that can transmit West Nile virus (WNv). In general, the corvid and non-corvid families of birds have different responses to the virus, with corvids suffering a higher disease-induced mortality rate. By taking both corvids and non-corvids as the primary reservoir hosts and mosquitoes as vectors; we formulate and ...
