It can, but probably won't. When Winged Rhynos is summoned, the turn player still has Priority, so when he passes, Bottomless Trap Hole can be used against the summon. Winged Rhynos though has a Quick effect that he can chain to BTH's activation, meaning he will remove himself from the field and BTH will resolve without effect.
Even if a second BTH was chained to Winged Rhynos' activation, Winged Rhynos could activate again in chain to that.

So, it would depend upon the type of deck you planned to use or went up against, but most people would choose "Bottomless Trap Hole".
