At least that is what the answer was when I asked for Bird ID on a Southern California Face Book birding group. I had never seen one up close that I can remember.
While my wife stalked the wild Pokemon I sat in the car and read or took pictures out the window in between driving her to various locations. A whole flock of these little guys, with a few sparrows were hanging around the gate of the "California Citrus State Historic Park" in Riverside, CA. It is 400 acres toatal with 248 acres in orchards with a visitor center, picnic areas, trails, a huge variety of different citrus fruits and a large fruit stand where they sell fruit from the park's trees. The land is hilly with over 100' differences in elevation.
This is from one side of the street across the street and then about 8-10 feet to the fence. They are small, just a bit bigger than a Lesser Goldfinch. So these are extreme crops.
It was cloudy bright with the light level going up and down but never bright enough for distinct shadows. Sort of like being in a giant soft box. (I almost always keep the camera on manual - RAW, with ISO on Auto while I set SS and f-stop.) Processing is in LR and PS.
All four shots are with Canon 5DIV, Tamron 150-600 G2 @ 600 hand held or resting on the car door out the driver's window.
#1 1/400 @ f/9.0, ISO 2500
#2 1/400 @ f/9.0, ISO 2000
#3 1/400 @ f/9,0, ISO 1600
#4 1/200 @ f/6.3, ISO 400

I recently photographed an African Collared Dove hanging around with Mourning Doves at Bolsa Chica this Fall. Beautiful nearly white dove with red eye. I’d never seen one before. One of your posts mentioning the collared doves made me aware of the possibility that this is what I was seeing. I do believe human actions contribute to but are not the sole cause of global warming. I don’t know how much human intervention can hope to mitigate the warming trend. I agree that all these factors contribute to the changes in species distributions, etc. Other factors (banning DDT, for example) can be very positive human adjustments to human caused problems. I’m reminded of this every time I watch both Brown Pelicans and American White Pelicans flocking here at Bolsa Chica and elsewhere along the coast.

In Feb last year I saw Mourning Doves, Eurasian Collared Doves, African Collared Doves and Band Tailed Pigeons in my back yard at once along with house finches and at two types of sparrows. I got one frame with three of species at once. Two totally out of focus, but three of them together within about 2 feet of each other and the fourth species was perched over head waiting its turn.
Sort of co-op feeding, the finches and sparrows on the feeders being messy and tossing food all over and the doves and pigeons underneath the various feeders doing ground clean up.
