To the guy with the blood wyv looking for the ice wyv, yes, ice wyverns are still tamable.

However, NESTS ARE NOT GURANTEED TO SPAWN. You'll need to look at the multiple different spawn points for nests, and hope a nest spawns. I'd recommend using the Ark Wiki's list of nest spawns, they are usually listed on the "Resource Map". If you've checked all locations and they still haven't spawned, kill the ice wyverns and then fly far away to unload the zone, and come back to reload it. I personally, however, would not recommend getting an ice wyvern at all, as they are widely considered the worst wyvern type. Go for Lightning or Poison instead!
