Upper Newport Bay is an estuary that is an important staging area for migrating birds in winter. In summer the walking trails brought me close to bush birds and raptors. Turkey Vultures, Red Tailed Hawks and Osprey circled overhead, but the marine layer made distant photos a dull grey. I still haven't identified many of the little brown birds, but the Anna's Humingbirds were numerous. Anna's are the most common hummingbird in Southern California. The way the light fell made a spectacular difference to the colours they displayed, a small turn of the head and the colour was gone.
