1. A bird feeder comprising: a seed reservoir having a wall with at least a first feed port and a second feed port therein through which birds can access seed held within the reservoir, said first and second feed ports being spaced apart and in generally vertical alignment with one another; a perch positioned adjacent the first and second feed ports and extending outwardly from the reservoir wall, said perch being fixed with respect to and supported on the reservoir wall, said perch being between, vertically aligned with, and generally equally spaced away from said first and second feed ports; and an adjustable port element rotatable with respect to the reservoir wall, said adjustable port element configured to rotate between a first position in which the port element allows birds to access feed through one of the first and second feed ports only while hanging upside down from the perch, and a second position in which the port element allows birds to access feed from the other of the first and second feed ports while standing in an upright position on the perch, said adjustable port element including a mounting end rotatable around said perch and a second end distal from said mounting end, said second end having a blocking structure that prevents access to said first feed port or said second feed port as the adjustable port element is rotated around the perch into one of said first and second positions.
