Yes, they are. During breeding season, they maintain and defend territories against other males, and are one of species most notorious for attacking their own reflections in car windows and other reflective surfaces. In the winter, they will sometimes bully other birds out of the way at feeders. They are not nearly as aggressive as blue jays, but they are more pushy than most finches, for example.

During breeding season they are. Over the winter, not so much. They will gather in groups around feeders, and while they establish something of a pecking order, they are much more tolerant of each others' presence - although this may because what's being seen is a family group. I don't know that anyone has studied winter groups in that much depth.

All birds are territorial during the breeding season. All maintain and defend territories against other birds.
