Solution

The correct option is D Crop glands
a crop gland can be defined as an expanded, muscular pouch near the gullet or throat in the birds. It is a part of the digestive tract, essentially an enlarged part of the oesophagus. The crop is used to temporarily store food. Not all birds have a crop. In adult doves and pigeons, the crop can produce crop milk to feed newly hatched birds.
Both female and male pigeons produce a nutrient rich substance in their crop to feed their young (squabs). This substance has been likened to lactation in mammals and is referred to as pigeon ‘milk’. This ‘milk’ is essential for the growth and development of the pigeon squab and without it, they fail to thrive.
