Hybrid morphology radio sources - follow-up VLBA observations
  Hybrid sources that present FR I - like jet on the one side of the radio core
and FR II - like on the other are rare class of objects that may posses key to
understanding the origin of FR division. We presents information connected with
the new high resolution VLBA follow-up observations of 5 recently discovered
hybrid sources. We believe that sources which exhibit two different
morphologies at the opposite side of the radio core are FR II type objects
evolving in non-uniform high-density environment.
