Little information. Foraging behavior has not been described. More generally, the behavior is similar to that of other jays (Ridgely and Tudor 1989). The Cayenne Jay moves "silently, almost stealthily, through mid. or lower levels of [the] forest, [although] at other times straggling along while calling noisily" (Hilty 2003). Haverschmidt (1968) described it as shy and difficult to observe.

There are no data on territory size or spacing. Cayenne Jays appear to exhibit group territoriality (Bosque and Molina 2002).

No information.

The Cayenne Jay demonstrates many characteristics of communal breeders. They occur in family groups when breeding with more than 2 individuals feeding nestlings. No aggression between group members near the nest has been observed. Individuals also participate in allopreening (Bosque and Molina 2002).

Little information. Bosque and Molina (2002) induced group mobbing behavior in Cayenne Jays by placing a preserved specimen of a boa (Boa constrictor) beneath an active nest.
