[Tweeters] Mixed junco/house finch flock

[Joshua Rosenau via Tweeters]

I’ve noticed lately that a group of juncos (8 or a dozen) has been gathering in my yard, usually close to what I take to be a family group of house finches. They seem to all be foraging together, though I suppose it could just be a random assemblage. I don’t see any unique food source they’re clustering around, though. Just wondered if this was typical or something others had seen elsewhere. 

Thanks all,
Josh
