Agree. Sorry for this dumb question..what does the seaweed/plant signify though? Got a story for the Liverbird?
,Above the heart of Liverpool the eponymous fowl flaps its wings, a landmark for mariners atop the famous building which bears its name, a heraldic device for schools and colleges, the badge of my own 23rd Armoured Brigade, a totem for the city and the Corporation, borne on the coat of arms of ancient tramcars, but false and fictitious as the roc and dodo. The 'Liver' in Liverpool is a corruption of the word used by the aborigines of the area, who being Ancient Britons spoke. Welsh. to describe the geographical location of the original hamlet, Llethr-pwll, (Still in Welsh, Lerpwll, "the slope by the creek"), still preserved in a nearby area as Litherland.)
Then what kind of bird was it meant to be? The story begins on Mount Ida, near Troy, where Zeus the King of the Gods espied a handsome youth and sent down an eagle to pick up the child Canymede and carry him up to Olympus to be his cupbearer. Now the Lords of Stanley in South Lancashire happened to be the hereditary cupbearers to the Kings of England, and one of them was advised by a wise man, presumably a monk with classical knowledge , that this legend was appropriate to his feudal duty, so he adopted as his blazon the Eagle and Child, a device still seen on many inn signs locally.
But when it came to designing the seal some local craftsman, who had probably never seen an eagle, drew a bird which rather resembled a duck, and not knowing that the eagle carries large items of prey in its talons, attached the strange burden to its beak. Subsequent copyists did little to improve the device, so that the 'child, looked more like a fish, a twig or a leaf and the carrier looked like a cormorant, a bird which I often saw before the war in the estuary, an apt sample of Mersey marine life. Then by artist's license the legs were lengthened and the shape was more like that of the heron. Hence by a false derivation the product of an artist's imagination was immortalised as a Liver Bird.
