TRUE! Well, kind of:
Pigeons do not produce milk. Like other birds, pigeons lack mammary glands and do not nurse their young with milk. Instead, pigeons feed their chicks with a substance known as "pigeon milk," a secretion produced in their crops (a part of their digestive system). Pigeon milk is regurgitated and fed to the chicks during the early days of their lives, providing essential nutrients for their growth. It's not true milk as mammals produce, but a unique adaptation in pigeon parenting.
