TITLE: Great Blue Herons nesting at Stowe Lake, GG Park, San Francisco
DESCRIPTION: What follows are a series shots taken over an hour showing the males going out, bringing back sticks for the nests and at the end, a coupling between one pair. I witnessed three couplings in the hour and 15 minutes that I was there.
