Attracting birds high up
We live on the 19th floor with a 'french balcony' (doors opening up to a balcony fence but no actual balcony) and we enjoy watching birds. We know we probably won't attract many birds, if any, at this height. Nevertheless we'd like to try and see if we can get some up here.
I bought a balcony box in which I plan to plant some plants which attract birds (through their berries, seeds or the insects they attract). Maybe we need self-pollinating plants because not many bees might make it up here.
The space in the balcony box is limited. We plan to attach some type of small bird feeder to the box.
Does anyone have any ideas which types of plants would help us attract birds? Preferably something low maintenance and nice to look at.
Thanks a lot!
