According to the Orthodox Union, there are several species known as “quail.” Among those commercially available in the United States, the coturnix is accepted to be kosher. They further advise that the eggs of this quail look different from those of the bobwhite and button quails, which are not recognized as kosher.

White eggs belonging to the bobwhite are easily identifiable and may not be eaten. However, one must be adept at identifying the differences between the splotches on a button quail egg and those on a kosher coturnix egg.
