The Raven, a clever bird.

Now here's a bird with attitude. Both Ravens, and Crows, can recognise faces and human voices, and have the ability to pass this information on to future generations.

"And the raven, never flitting, still is sitting, still is sitting
On the pallid bust of Pallas just above my chamber door;
And his eyes have all the seeming of a demon's that is dreaming,
And the lamp-light o'er him streaming throws his shadow on the floor;
And my soul from out that shadow that lies floating on the floor
Shall be lifted - nevermore!" Edgar Allan Poe
