One sign of spring is the appearance of the first Harbor Seal pups.Here's a photo of a newborn pup. It's important to keep humans and dogs off the beaches where these pups are born. At The Sea Ranch, near Shell Beach, docents are on the bluffs to inform people about their presence.

Here the newborn is nursing. Doesn't the mom look blissful?

And lambs appear at The Sea Ranch flock. Life is good when all you have to do is munch the fresh grasses!

I'll be sharing more photos of spring with you in the days ahead. Thanks to Allen for allowing me to share his photos with you here. To see more of Allen's nature photography, here is his website: http://allenvinson.smugmug.com/
