From Pathfinder Wiki

Other trees that can be used for whistle-making include:

Alder, aspen, and poplar
These species can also be used for making slip-bark whistles. As with any slip-bark whistle though, they should be made in the spring or early summer when the sap is up. After that, it's too difficult to slip the bark off the wood.
Elderberry
Elderberry has a pithy core that can be easily removed. In this case, the bark is not used as the outer sheath, but rather, the whole twig is. You must find another piece of wood to fit tightly into the pith and shave off the top edge of it to make the whistle.
Sumac
If you select a sumac tree, make sure it is not a poison sumac tree (Rhus vernix). All parts of the poison sumac contain the same resin as poison ivy and can cause a person to suffer from an itchy rash. Poison sumac has white berries. If the sumac has red berries, it is OK to use and will not cause a rash.
