You won't find milk like this in the grocery store 🥛 Crop milk is secreted from the digestive tracts of some birds (like flamingos) and regurgitated to feed young chicks. Sounds tasty, right? Both male and female flamingos can feed the chicks this way. This high-protein smoothie contains a chemical called canthaxanthin which gives it its red coloration. #gotmilk #stinkypinkies #flamingos #sdzsafaripark | San Diego Zoo Safari Park
