Although I have never really been into my 'yardlist', we have intermittently maintained seed and hummingbird feeders in our backyard, usually at the initiative of my wife, Remy. Since we moved to our current address, we have made a bit more effort and have had a few birds of interest, including six species of hummingbird and occasional visits by one or two White-winged Doves. However, we have had very little out of the ordinary with respect to seed-eating species, despite backing on to agricultural fields and having a regular flock of White-crowned Sparrows.
This fall, I have put more effort into making sure the feeder is filled regularly and also scattering seed around on the ground so the sparrows can easily access it, without having to wait for the House Finches to displace seed from the feeder.
This proved effective as I quickly built up a small flock of White-crowned Sparrows and juncos, as well as attracting the usual suspects to the feeder itself. Interestingly House Sparrows may be heading the same way in my part of California as they have back in their native UK as they have become distinctly less common locally, with just a couple showing up at the feeder.
After a few days, I noticed a Song Sparrow appearing among the sparrows and a further day or so later I saw a Lincoln's Sparrow. This was the first time there had been one in the yard for a few years. After seeing a high frequency of Lincoln's Sparrows sightings, I began to suspect there might be two. I upped my watching efforts a bit more and confirmed this. While doing so I noticed a largish sparrow that apparently had a fairly well-marked supercilium but with underside streaking much less well-defined than that expected for a Song Sparrow. Suspecting a young White-throated Sparrow, I went off to grab my binoculars and was able to confirm it indeed was. The bird hung around for the next couple of hours and I was able to get some pretty nice photos through the window.
White-throated Sparrows are uncommon but widespread winterers southwards from SW Washington State along the west coast. However, they thin out considerably as one heads further south in California. There are several other birders in Goleta and Santa Barbara who have them visit regularly but I suspect their yards are in areas with more trees and bushes. White-throated (and Golden-crowned) Sparrows definitely prefer more densely vegetated habitat to White-crowned Sparrows and I suspect this is why I have never seen one in the yard before. Golden-crowned is also a very occasional visitor, usually in late winter or early spring when natural food sources are diminished. As far as I can tell, the White-throated Sparrow just dropped by for the day.
