Reading the Graph: Who do Red-winged Blackbirds try to displace? Recall a displacement is when one bird tries to dislodge another bird and it can be either successful or unsuccessful. The orange bars show displacements in which the Red-winged Blackbird was successful and the blue bars show the displacements in which the Red-winged Blackbird was unsuccessful. The length of each bar indicates the number of displacements and the species listed on the vertical axis are the species that the Red-winged Blackbird tried to displace.
