This young pigeon showed up in our yard a few weeks ago. It was searching for food pretty much all day below a feeder that's hanging in the garden, desperately looking for scraps that the finches and tits would leave. I felt a bit sorry for it. When it made its way to the balcony i gave it some seeds but quickly stopped doing so again, because it started squatting the balcony for the whole day. I don't want it to think that life is about hanging out on the balcony, waiting for someone to show up with seeds.
A few days ago then i was watering the balcony plants in the evening and noticed pigeon shit on the basil. I looked up and there it was sleeping:

(was a lot darker than it seems on the photo)
It must have slept there the night before already. I moved the basil and built some kind of poo catcher. Quite impressive how much poo it left in a night ๐
It stayed for about five nights but yesterday it did not show up, i guess it was too busy on the balcony. Still leaving the poo catcher for now in case it shows up again tonight.
I both like your thoughts on what the pigeon is doing and also your food cage.
Thanks, yeah i have been very happy with the feeder, i have removed it a couple weeks ago, but for the winter season i am going to build a new one like that, just a bit roomier and with more sticks to perch on towards the balcony windows.

Here's a better view of it:
V cool, dig it
