Rabbi Yitzchak Hershkowitz, who runs the Chabad Center in Los Cabos, Mexico,  reports having found a kosher para adumah that would be ready when Mashiach arrives.

The rav found the red heifer while visiting a local farm in search of chalav yisrael. While milking a cow, he saw it with a young shepherd on the farm. He learned it has not yet calved and he rushed to document the animal.

The last red heifer that was believed kosher was in New Jersey about two years ago. However, it gave birth to a black cow shortly after its second birthday and hence, rejected as a para adumah.

That tag on the cow's ear makes me suspicious that this might invalidate the cow. Any experts on Para Aduma that know if it's a halachic problem.
As far as the Para Aduma in New Jersey I heard it was invalidated for other reasons.
