Bipedal humanoid birds with wings, clawed hands and feet, and an avian head with a sharp beak, kenku are mischievous creatures which habitually use their limited magical powers to annoy and inconvenience humans, though their intent is not usually to kill.
If a group of kenku is encountered, its members will depend on the group size. A small group will contain two creatures of 2 HD and two of 3 HD or three and two respectively; a group of 6 or 7 will contain a leader of 4 HD, two creatures of 3 HD and three or four of 2 HD while a group of 8 will contain a supreme leader of 5 HD.
Kenku over 2 HD have additional magical powers in the form of spell-like and innate abilities.
It is rumored that kenku of more than 5 HD exist with even greater magical powers. Kenku lairs so far discovered have been small underground caverns but it is believed that larger caverns, deeper underground, contain larger numbers of the beasts in a formalized social structure.
Particularly adventurous kenku have been known to their change shape power to assume the form of a god and accept offerings from credulous worshipers, and this is but one example of the bizarre uses to which kenku, and particularly the younger of the species, have put this power.
Again, these powers are sometimes put to unusual uses, but these kenku tend to be older (the innate abilities develop with age and suitable training) and less reckless in their activities.
Kenku favor kidnapping as a source of funds. They will freely give treasure but this is rarely genuine and will crumble to a valueless dust within a day. They will appear helpful to humans and will offer nonverbal advice, though this is usually carefully designed to mislead and to tempt the party into danger and/or difficulties. As a rough guide, the approximate chance of a kenku actually aiding humans is 5% although this will vary with the circumstances.
Kenku do not speak; they appear to communicate with each other on the telepathic level.
