I was at the Brickworks today. Bluebirds were present (6-10). they were a pain to track and follow, but I got some amazing views at the end.
Also noted were 2 raptors (no time to ID them), myrtle warblers, robins, a mockingbird, goldfinches, juncos, 2 wood ducks, cardinal, hairy woodpecker, various sparrows and ruby-crowned kinglets that gave an excellent show.
my bluebird photos will be posted at the end of the week. just an FYI
