Nicola Clayton is a psychologist who studies western scrub jays, Aphelocoma
coerulescens, and has done experiments strongly suggesting that the birds plan ahead.

Animals that are likely to be important dispersers of nuts in temperate Holarctic forests include rodents belonging to Sciurus, Spermophilus, Tamias, Apodemus, and Peromyscus, and corvids belonging to Garrulus, Cyanocitta, Aphelocoma
, Nucifraga, and Corvus.
Other bird species endemic to the Sierra Madre del Sur massif of central Guerrero include the jay Aphelocoma
guerrerensis, the woodcreeper Xiphocolaptes omiltemensis, and the hummingbirds Eupherusa poliocerca and Lophornis brachylopha, although only the latter two are recognized broadly by ornithological authorities (Navarro-Siguenza and Peterson 2004, Peterson and Navarro-Siguenza 2009).
