The Caucasian Eagle was another offspring of Typhon and Echidna.
It was also a sibling of the Hydra, the Sphinx, etc. It lived
in the Caucasas Mountains and said to be huge.
It didn't have a very large part in mythology except that
its job was to rip out the liver of the Titan Prometheus
every day and devour it. It diligently did that until killed
by the hero Heracles who happened to be passing by and felt
sorry for Prometheus.
