I’m with you Mavis, I’m scared of them too. I reckon they’d have my eyes out if they got close enough.Yes, brazen! That's the word. Just aggressive for zero reason too. I detest pigeons, they scare me so much and I'm one of those people who walks along screaming if they come near me, its embarrassing but these guys are bad news, I honestly think they look for vulnerability.
Monga bird flu only goes for ducks and such I think.
I hate saying it but someone needs to shoot them.
