Do pigeons lactate for their young?

Pigeons do indeed produce a substance known as "pigeon milk," which is not milk in the traditional sense but a nutritious secretion from the lining of the crop, a special pouch in the throat. Both male and female pigeons produce this substance to feed their chicks. Pigeon milk is rich in proteins and fats, making it highly suitable for the rapid growth of their young during the first few weeks after hatching.

This ability to produce pigeon milk is unique to a few bird species, including pigeons and doves, and plays a critical role in parental care. The chicks rely entirely on this food source until they are old enough to consume solid food, highlighting the importance of this nutritive secretion in the early stages of their development.
