We like to feed the birds but have had problems with pigeons, parakeets and squirrels. The squirrels can defeat almost anything. They used to avoid the balconies but this lot have discovered (or become willing to) climb up the walls or jump from a nearby tree.
So, the latest plan is to hang a feeder, probably a Squirrel Buster Mini, from the bottom of the balcony above, in the best possible position and as high as possible, probably with a clear baffle above it.
I think this should work for the pigeons and hopefully the squirrels. But parakeets may give it a go - to repel them, I’d need to go for a guarded feeder rather than a spring-loaded one.
Any suggestions or alternative approaches?
