My collection of local birds is about 25 species so far. They are fun to watch because they display interesting behaviors and sometimes seem to have personalities like this grumpy YELLOW RUMP WARBLER (left). The names can be pretty funny too. This immature is also called the MYRTLE WARBLER. Or it may be a BAY BREASTED or a BLACKPOLE - these guys are tricky. If you see a glaring error please make a comment.
On the right is an immature
