Just yesterday I was commenting on not having seen an American Tree sparrow in the backyard for a few years now and therefore ... what gives? They used to be common and their visits reliable. I started noticing a dearth of these little birds after about 2015. I might still find one in a park or a designated hot spot, but never many of them at once. Even eBird only occasionally mentions Tree sparrows, where perhaps one might be reported by someone at a location but never in numbers.
This morning at about 9 o'clock I spotted a single ATS in the backyard. It didn't go anywhere near the feeder for a good 90 minutes and then visited only once, apparently finding the competition with chickadees, juncos, a Downy and a WBNH just too much to endure. The neighbours cat may have played a role in there as well. Anyway, the day after my complaint I saw my FOY Tree sparrow. I wonder if it will be back tomorrow? A few days ago a flock of goldfinch dropped by and utilized the feeder for about 5 minutes and then the whole flock disappeared. What? My grub is not good enough for you?
