Caching is very common in almost all Corvid genera worldwide. de Kort and Clayton (2006) performed tests with captivated birds and compared it with literature sources. Nucifraga, Perisoreus, Garrulus, Cyanocitta and Gymnorhinus are thereafter highly specialized cachers. No caching is known for the South-American genus Calocitta. All others are moderate cachers, as their ancestor might have been too (see Fig 1 in de Kort and Clayton, 2006).H
