Along with some red-winged blackbirds. I believe these are mourning doves. Or they could be Eurasian collared-doves.
About Lloyd Kahn
Lloyd Kahn started building his own home in the early '60s and went on to publish books showing homeowners how they could build their own homes with their own hands. He got his start in publishing by working as the shelter editor of the
Whole Earth Catalog with Stewart Brand in the late '60s. He has since authored six highly-graphic books on homemade building, all of which are interrelated. The books, "The Shelter Library Of Building Books," include
Shelter,
Shelter II (1978),
Home Work (2004),
Builders of the Pacific Coast (2008),
Tiny Homes (2012), and
Tiny Homes on the Move (2014). Lloyd operates from Northern California studio built of recycled lumber, set in the midst of a vegetable garden, and hooked into the world via five Mac computers. You can check out videos (one with over 450,000 views) on Lloyd by doing a search on YouTube:
Eurasian Collared Doves, I think. Just a few years ago, these were rarities here in coastal BC. Birders would come from all over to see one. Now we have hundreds of them and they seem to be driving the local feral pigeons away. I guess you can still make pigeon pie from them though.
