Do you not get something like 30 days to register a birth (I think this was extended during lockdown). How much of a Jakie do you have to be be that you are not sober enough in 30 days to register a name properly
Have to admit I am stumped. Bouncing tail is interesting though, very few birds do that- wagtails, dipper and sandpipers are the only ones I can think of.
I would guess a juvenile of some sort although not sure of what with the description
