This 3 minute video shows the birth at a wide angle taken on a gopro camera mounted on top of the bunker/desalinator building. The camera is in a weatherproof housing so the sound is not very good.
At 0:45 the pup is out
At 1:40 Chunk starts climbing over the pathway
And at 2:27 Chunk comes in contact with the pup
