Welcoming a new chick - young Pigeon to this beau World !!

During Covid pandemic, I watched with horror and helplessness a young one unable to properly bring out its child -  it  is so commonly seen and known but its scientific name would make it unintelligible – ‘clade Columbidae’ – it is the common Pigeon.  That time, its egg kept in the shade of a window in the house opposite to me just fell down after 10 or 12 days, again watched such bungling couple of times and thought these Pigeons are incapable of upbringing.
