High spin states of {sup 144}Dy have been studied through in-beam {gamma}-ray spectroscopy by using the reaction {sup 92}Mo({sup 56}Fe,2p2n). It has been found that the continuation of the ground-state band forks into three {delta}I=2 bands above the 8{sup +} state. This forking has been attributed to the alignments of {pi}h{sub 11/2}{sup 2} or {nu}h{sub 11/2}{sup -2} configurations with the help of the systematics in neighboring nuclei. Additionally a negative-parity sideband of {delta}I=2 cascades has been observed to start from the 5{sup (-)} state and continue to a dipole band above the (13{sup -}) state through another negative-parity sideband of {delta}I=2 cascades in between. These structures have been discussed from the viewpoint of a competition between ''Magnetic Rotation'' and ''Anti-magnetic Rotation'' based on a classical particles-plus-rotor model.
