I like 'em !
Used to have a pet one as a lad !
Can call one of the local daws to the bird table from several gardens away !
They can be gluttons on the bird table but i now only feed in hard weather .
The term evil* i reserve (wrongly) for the carrion crows , magpies and black backed gulls.
Daws are saints compared to the local gulls.
*wild animals are rarely evil, just not living to our rules.
Ps
How many gulls would you like me to send to solve your jackdaw problem?
Got lots !
