How big would you say the bird was?
Perhaps you spotted the famed "Thunderbird"

Cryptozoologist Loren Coleman claims that sightings of Mothman continue, and told USA Today he re-interviewed witnesses described in Keel's book who said Mothman was "a huge creature about 7 feet tall with huge wings and red eyes" and that "they could see the creature flapping right behind them" as they fled from it.
Wildlife biologist Dr. Robert L. Smith at West Virginia University told reporters that descriptions and sightings all fit the Sandhill Crane, a large American crane almost as high as a man with a seven foot wingspan featuring circles of reddish coloring around the eyes, and that the bird may have wandered out of its migration route.

The liger is the largest known cat in the world.[1] Imprinted genes may be a factor contributing to huge liger size.[4] These are genes that may or may not be expressed on the parent they are inherited from, and that occasionally play a role in issues of hybrid growth. For example, in some dog breed crosses, genes that are expressed only when maternally-inherited cause the young to grow larger than is typical for either parent breed. This growth is not seen in the paternal breeds, as such genes are normally "counteracted" by genes inherited from the female of the appropriate breed.[5]
