Chitty.

"Wren, Troglodytes troglodytes
Other Names:
There are many names for a Wren, Jenny probably being the most common, but others are Chitty Wren in the north country; Cutty (North and West England) and Stumpit (Lancashire) from it’s short tail; Tom Tit (Norfolk) and Tintie (Nottinghamshire) from it’s small size; and Crackadee (Devon) from it’s song, which is said to have the most notes of any birdsong in the world. Also Cracky and Crackit from the same region."
This villain plagues me damnear every day, by appearing around the time I'm either getting Breakfast or washing up Breakfast gear. As a general rule it stays JUST long enough to grab camera, change lens and get back to window.
Fooled it this time, I was in kitchen at a different time , and the lens wasn't to change, having been trying to capture the many hues of a Starling
Thank (insert Deity of choice) for the "Extra photos" facility.
