Towards the end of July we start to see the Harbor Seal mothers hauling out on the island near us. By the end of August they're mostly gone. Sometimes we see a mother on the shore and then soon after, a mother and a pup. Presumably she's just given birth. The pups can swim within hours of birth but they tend to hang around on shore a lot at first. Harbor Seals have a single pup that the mother cares for. The males don't help.
Here is one of the first pregnant ones this year.
And a mother and young pup.
Harbor Seals vary a lot in color, darkness, and pattern. They tend to look darker colored when wet, and lighter when dry. The younger pups have loose skin which they rapidly grow into feeding on their rich mother's milk.
I think this is another pregnant one
visited by a mother and pup. Harbor Seals are normally solitary but at this time the mothers and pups are often seen together.
By the end of August the pups are getting almost as big as the adults.
Note: It might look like I'm getting very close to the seals, but I'm not. These photos were all taken from the mainland which is about 200 feet from the island. I just have a big telephoto lens. If the pups are approached too closely the mother can abandon them. The worst offenders are kayakers and paddle boarders getting within a few feet to get cell phone photos. These seals are accustomed to humans but they are still wild animals. In a recent incident, one tourist kicked a seal pup off a dock and a second tourist jumped into the water to "rescue" it. Craziness. Just keep your distance and let them be.
