They're definitely nest building. One is in an ash tree visible from
my
study window. It tweaks off twigs and flies off with them to my study
chimney!
I'd forgotten this charming but destructive habit of theirs!

Mine are fighting up on the roof as I write, the noise and banging is
incredible :-)

We are convinced our local Jackdaws (we have hundreds around us) swear at us
down the chimneys since we fitted bird guards to them all.
