I think that’s where ours are in summer as well. I do hear them in the mornings but don’t see them so much as in winter, when they’re regular visitors to the balcony. I don’t feed so much in the summer as I actually want to be able to use my own balcony!
Yeah, I understand about using your balcony without cleaning it up several times each 24 hours. Mmh, they'll be somewhere where their special purpose beak shape is being put to excellent use to feed themselves, but also issuing forth their inimitable sounds of fervent social interactions! 😆
