when birds have more food available than they are 
able or willing to eat at once, especially if the food is 
of a kind that will remain edible for some lime 
(Goodwin 1976). This behavior is poorly documented 
in Cyarutcomx jays. Caching behavior was observed 
in captivity by the Tufted Jay. but it does not appear 
to have been observed in the wild (Crossin 1967). 
Anjos (1991) observed this behavior in Azure Jays in 
both captivity and in the wild; this species was 
observed storing seeds of Araucaria crngustifolia in 
the canopy of the MF (Anjos 1991). The Flush- 
crested Jay caches the seed of A. angustifoliu on the 
ground, and it should be considered as an incidental 
disperser ol this tree species. Some seedlings of A. 
angustifolia were recorded in places, around the 
animal breeding center at KEP, where individual 
Plush-crested Jays were observed caching seeds of 
this tree species. 
The Plush-crested Jay exhibited variations in: (I) 
forest strata occupancy (preference for the under- 
story and middle level ol the forest, frequently 
using the ground where there was human food 
supplementation); (2) territory and home range 
sizes (both smaller when food supplementation was 
available); and (3) foraging behaviors (more 
diverse in less disturbed habitats). These charac¬ 
teristics demonstrate the plasticity of this species in 
habitat use, similar to most species of Corvidae.
