In an adventure I'm running, the characters will probably retrieve arrows from skeleton archers. In their quivers, one of the arrows is a +1 arrow.
How can the characters differentiate magic items from normal items? Is it only a visual clue? Do they have to cast the Detect Magic and Identify spells?

This is answered by the Identifying a Magic Item section on page 136 of the DMG (I won't quote the entire text):
In the end whether a PC can differentiate a magic item from a nonmagic one comes down to how the DM wants to present the item and details about the item and whether the PC actually "handles" the item. Short of that, Detect Magic would give a PC a visual on if an item is magical without them having to handle it first.
