Stampeding Wildebeests and Skyshroud Behemoth fading timing upkeep magic

[riolu]

if I have Stampeding Wildebeests and Skyshroud Behemoth, at the turn that the behemoth is supposed to fade away can I return it to my hand or do both abilities happen simulatenoulsy and the behemoth will die before i have chance to return it to my hand?

Since you control both triggered abilities, you can put them on the stack in any order you choose, so you can bounce the Behemoth before you have to sacrifice it.
