don't think i posted this already. their skills underwent a big change from 3.0 to 3.5 - monstrous humanoids formerly had "2x Int (+2/extra HD)", and now only have "2+Intx4 +2+Int/HD" - a big difference! for a 2-HD kenku would have been 22 before, and is now only 10. keeping that in mind, here is the before and after picture:
3.0: Disguise +6, Escape Artist +4, Hide +6, Listen +3, Move Silently +6, Open Lock +4, Pick Pocket +4, Spot +3 (only bonus is Disguise +4 racial)
3.5: Disguise +6, Escape Artist +4, Hide +6, Listen +4, Move Silently +6, Open Lock +4, Search +4, Sleight of Hand +6, Spot +4
Skills: Kenku receive a +4 racial bonus to Hide, Disguise, Listen, Move Silently, Search, and Sleight of Hand checks.
