Ostrich & Archeology

Since Mojang has added both the copper golem and the frog, both a vote loser, i have a suggestion if the ostrich will be added, it is that we can add a suspicious dirt, which would spawn on savannah biome. Ostriches would spawn on that biome, and they have the ability to sniff and located suspicious blocks ( sand/gravel ), i suggest also adding a suspicious dirt/grass block for this, this would make archeology more fun and easy for players
