Hello Pigeon Lovers! I recently discovered a nest, parents and 2 babies outside my window in a planter attached to my high rise building back in mid March. I have had front row seats to their entire lives the past 6 weeks and I've loved every minute. The mother left awhile ago, but the dad has been here daily raising the babies. They finally started flying and have gone to the building across the street but always back here to mine where they sleep, with the father here nearby as well. I also noticed another bird around just yesterday and wondered if they were finding mates already. This morning they all left early, but only 1 returned late this afternoon. The father has since been back to check on him twice, but left again and has not returned. My question is, is it normal for them to leave and start their lives at different times? Would the father abandon the one that is left here? This is hopefully unrelated but I have noticed a louse fly in it's feathers, and it has a few small mud balls on 3 of its toes. Is there any chance it could be ill and that is why it's still here alone? I had made a point of not feeding them (other than water) as I didn't want to interfere, so I have not cleaned their space yet either. Maybe I need to clean and disinfect the area now. I am just wondering if all this is a normal. It's sad to see only one here sleeping all alone tonight for the very first time. Any insight would be greatly appreciated. Thank you and have a nice evening!
