The Falconer is a Ranger archetype from Ultimate Combat. In the description there are three new animal tricks: Roam, Distract, and Swooping Charge. Are these tricks available to any PC with an animal companion? A quick read I would say no, but there are now more tricks available from Animal Archive and more PC options with animal companions in the Advanced Class Guide.
I ask because I'm looking at building a Hunter with a falcon animal companion.
