Long-tailed Tit
Aegithalos caudatus
Let's start with the modern 'birder' name for this charming bird, 'Lollipop', with that long tail and pink other end it is a fitting epithet.
Of all the numerous archaic names we have for this beautiful and cheerful little bird 'Bum Towel' is perhaps the least complimentary. I mean seriously guys what are you thinking? Apparently, this was used because of its colour, as was Bell ringer and Millithrum or Miller's Thumb.
From the penduline shape of its nest it was also called Bottle tit, Jack in a bottle, Pudding bag, Poke pudding and Poke bag. Lastly, we have Long-tailed mag, Long-pod, long-tailed mufflin, Mumruffin, Ragamuffin, Fuffit. The last four because of the tufted feathers around the neck resemble a muffler.
