Here is a sequence of photos showing a greeting between a mother coyote and her yearling offspring, a male. The full-grown pup is 17 months old. Not only is there plenty of affection, but the yearling shows very strong submissive behavior: coming in from below, constantly seeking mouth contact. Interestingly, each coyote appears to close its mouth over the other’s — but one does it from a crouched position. The mother is on the right-hand side in all of these photos.
