I have a pecking noise when I crank it cold. on 2005 Toyota 4Runner

The noise will last around 8-10 seconds and then go away. Is it a lifter, evac pump or what? It's not valves loud for that. It has done this for ages and is really annoying, although it doesn't seem to be hurting anything (yet that is).
