Hello, Apologies in advance if this seems like a stupid question, I've only just recently started taking notice of nature and during lockdown I have been putting out sunflower hearts on a bird feeder tray in the garden, end of March. They absolutely LOVED it, I had collared doves, wood pigeons, songbirds, sparrows, jackdaws, blackbirds, a parakeet and even a cheeky squirrel! As word got around the neighbourhood, more birds kept coming and I found myself having to top up the bird feeder EVERY DAY. I was going through 10kg of food a month at least. This started to become quite pricey and as a result I have stopped in July. Someone told me that in summer birds are not so reliant on help for food, but some of the baby collared doves who hatched at the time I put the food out and have been feeding off it ever since, keep coming back. There's no food there and I'm worried that because they kind of born into having the food there accessible, they won't have the life skills to hunt for it elsewhere. Is this true? Will they be able to survive without me feeding them now? And what is there other food source option what do collared doves usually eat in the wild? Thank you and will appreciate any help to put my mind at ease!
