11 grammes of joy
Blue Tits weigh 11 grammes, although it’s a little more when one’s fully laden with an egg.
Try describing a Blue Tit: a small bird which is blue, green, yellow and white with a pronounced wing bar, eye stripe, cheek patch, coloured crest, dark legs… it really is ornamentation gone wild.
There’s not a lot else they could throw in to get attention, is there? Apart from an ultra-violet crest in the males, which is invisible to us, of course.
