I received a pair of budgies as a gift, they're around a few months old and can fly.
Loved these guys more than anything, every day I change their food, put them in partial sun, cover them at night in a quite room, place foraging grass and seeds at the bottom of the cage to make them feel home, give them a small bathing container of water, give them fresh organic spinach and lettuce, etc
Anyway, last week I placed some grass at the bottom of the cage and when I closed the cage, it had a little tab that you need to put force to fully close else it's open around 2cm high.
After a few hours I came to give them food and noticed one missing - devastating.
How will this baby survive on its own, food/water…spent the whole day wandering around the neighbourhood playing budgie sounds on a wireless speaker, placed notes on the neighbourhood trees. placed food and water at the front, no sign.
it's the 3rd day today, ive spend the last 3 days going around on my bike looking around, shattering
It's a life lesson. They happen. Similiar happened to me with a bird as a kid. Not much you can do but put notices up online, neighbourhood, and be prepared (net or whatever) to try and catch and if it comes around to visit it's friend. Mine did, but i could not quite catch him, saw him maybe once or twice but then never again.
If it was properly tame you would have a decent chance of someone returning it. I recall some kind of parrot befriended my dad, it came inside he looked after it etc and found the owner looking for it online (need to be careful in verifying owners, lots of shady buggers out there).
