I have been witnessing for several weeks an all out war between an adult
male Rufous and an immature male Rufous at my feeders. It is not a normal
territorial battle that you might expect. It seems that on most occasions
one will wait for the other to go to the feeder. Then will make an all out
charge to drive to other away. Sometimes the attack will come as one
approaches the feeder. They always fly off into the neighbors yard, but
one is usually back within minutes to feed undisturbed. My theory is that
the immature is the son of the adult and is challenging dad for the
territory and mom. Any ideas out there?
