Hello I have a birds’ nest on my balcony (in one of the upper corners), they are sparrows, and they already have babies, I can hear them. Unfortunately, every time we go out on the balcony, the parents fly away, so it seems we cannot really avoid disturbing them… At least for now they keep on returning, and I have put some water and sunflower seeds on the top of a nearby cabinet…. I am a bit worried whether there is any risk for the babies to fall on the marble floor of the balcony once they start to learn to fly… Do you have any advice? 😊 Thank you so much!!
