Buzzard = Kite ?

Hi all
A quick question. Whilst speaking with a local here in Wales this morning, we spotted a Buzzard wheeling overhead and pointed it out to him. Oh you mean the Kite ? We were somewhat surprised that a local could mistake a Buzzard for Kite, until he explained that it was a Big Kite due to its wide wings and "fingers" at the end of the wing, Red Kites were the small Kite and had forked tails so were easy to distinguish from Big Kites. As anyone else come across this name for Buzzards ?
