Wroclaw Park in Lubin

Today we went do the park called Wroclaw. It is in Lubin. About 20 min drive from my home town. Some parts of it are very nice. It's been recently redone and has massive figures of dinosaurs lovely playground and mini zoo. But this part made me a bit sad. There are wild birds in the cages. They should be free. Not locked up. Specially storks. They are my favourite birds and it was upsetting to seeing them like this. It's nearly time for them to flight to warm countries ....
My dad thinks that they there probably because they sick or old. Hope he is right. Hope they are there for them own good
