The red-crowned woodpecker is a very diligent little bird, moving up and down the trunk of the tree at times while working, frequently changing trees along the branches, showing a preference for larger trees. It uses its chisel-like beak to pry open pieces of bark and search for insects below, sometimes descending to the forest floor and, over short distances, watching for traces of bugs in the fragments of bark that fall on the woodland.

The life of the red-crowned woodpecker differs greatly from that of other North American woodpeckers, being unique in that they are social birds, living in groups of two to five. Each family group roosts together, usually in the hollow cavities of ancient pine trees, which are often more than 100 years old. The female birds lay two eggs each year from late April to early June in a tree hole, with all members of the family helping to feed the chicks.
