There is one thing I'm confused with, and I apologize if this was answered before in another post.
"At 1st level, a falconer earns the trust and companionship of a bird of prey. The bird can be of any type of large hunting or scavenging bird (even a vulture). This ability functions like the druid animal companion ability (which is part of the nature bond class feature), but the falconer must take the bird animal companion, and that companion has only half the normal hit points."
And Hunter's Bond at 4th restores the bird to full HP. The question I have, is the Ranger's effective Druid level equal to his Ranger level, or still with the -3?
