I'm guessing you meant tree sparrows. (If not, you're going to have a stampede of birders to your house!) There's a flock of five or possibly six of these feisty little birds that spends a good part of every day at and under my feeders. They stick together faithfully all day and presumably all night, but when they're at the feeders each aggressively defends its own little patch of seed against its flock mates. They seem much more tolerant of the lone junco who keeps insinuating himself in their midst.
