Hey, come on, dirty minds.. there are other meanings; my favorite clean meaning - about which I can comfortably (usually animatedly) talk to me Mum, is... you guessed it - or would've if you'd not have yer minds in the gutter(s), 'Spaw, etc.. - is HUMMINGBIRD!

Seriously, "hummer" is also an old slang term for these "jewels of the air," & my 74 yr old Mom has just discovered birding (NOT brit slang... guess there's no way out!).

Cheers, BK
