Very little information. Gray-crowned Woodpecker often is inconspicuous, relatively inactive, and easily overlooked, more often heard than seen (Howell and Webb 1995, Gorman 2014). It forages at all levels (Howell and Webb 1995), including on the ground (Gorman 2014).
There is no published information on territorial defense, maintenance, or fidelity, or for territory or home range size, for Gray-crowned Woodpecker, apart from Schaldach's remark that "they apparently cover relatively enormous individual territories".
Undescribed. Gray-crowned Woodpecker presumably is at least socially monogamous.
Social and interspecific behavior
