Many species regurgitate food for their youngsters, including wolves, wild-dogs, gulls, bats and apes.
For coyotes, regurgitated food is a kind of pablum or baby food which is fed to them as the milk-weaning period ends at about 6 weeks of age. And regurgitated food usually ends as the parents begin bringing in more and more whole prey, and as the youngsters become proficient at hunting for themselves.
In this video, Mom rushes in to feed her brood and they know what’s coming: two of her three four-month-old pups dance with excitement around her, barely able to contain themselves, one emitting little vocalizations of anticipation. As the youngsters close-in excitedly towards Mom’s mouth, she has to weave herself through them to find space where she is able to regurgitate the large quantity of food which she has brought to them in her belly. Before it’s even all out, they dig in. . . . and she partakes in the banquet! Soon the third pup appears. There is sibling competitiveness, and in the end Mom begins to groom one of the pups.
It’s really cool that this occurred right in front of my field camera!

Incredibly cool. Amazing footage. I wonder why the third pup wasn’t more attuned. Probably not a good sign for it.

Third pup could have been napping, exhausted from play, in the bushes. :)) All three are very healthy.
