That is so sweet - and touching! - hearing the mama's cries, seeing her circling around, seeing the reunion.
The thread title reminded me of a time when I assisted in what we thought was a rescue of an abandoned fawn, not knowing that a doe will often leave her young alone for periods of time. Our worry was that there were some wild dogs in the area that could threaten the baby. But it was actually the wrong thing to do, and I have always regretted it.
