ITHACA, N.Y. -- The tiny Belding's ground squirrels appear to be "kissing". Instead, they are sniffing to analyze secretions from facial scent glands, hoping to learn from the complex odor bouquet who is family and who's not. More remarkably, they are determining in a matter of seconds precisely who is close-enough kin to risk their lives helping -- and perhaps even whether they are too closely related to for mating.
The above story is based on materials provided by Cornell University. Note: Materials may be edited for content and length.
