I saw this female Coastal Bushtit in Delta Ponds and felt fortunate to capture it with my camera. They are very active and are not still for long. You will see them moving about in low branches of vegetation in woodlands, pond edges, and parks, where they search for insects and some seeds.
Cool Facts (from 'All About Birds' - https://www.allaboutbirds.org/guide/Bushtit/lifehistory)
"•Bushtits are social birds that live year-round in flocks of 10 to 40 birds. They range widely in winter, sometimes moving considerable distances to escape cold weather. When nesting, a pair usually tolerates other flock members near the nest.
•The oldest known Bushtit was a female, and at least 9 years, 1 month old when it was recaptured and rereleased during banding operations in California."
