È stato studiato il comportamento di homing in colombi viaggiatori cui era stata asportata bilateralmente la porzione dorsomediale del telencefalo, corrispondente all'ippocampo di mammiferi. I risultati dimostrano che la struttura asportata gioca un ruolo critico in quello stadio del processo di homing mediante il quale il colombo rientra nella propria voliera una volta giunto nelle sue immediate vicinanze.
