Hand-Rearing Young Pigeons and Doves

Feral Rock Dove Chicks in NestA ThatBirdBlog reader in Bangkok, Thailand recently contacted me concerning the hand-rearing of Zebra Dove nestling whose parents had been attacked by a crow.  The incident reminded me that spring is on the way, and with it will come a number of calls concerning young pigeons and doves (or “squabs”), that have fallen from their nests or have otherwise become orphaned.  Those who keep pigeons and doves as pets, or who “fly” them as a hobby, are also sometimes called upon to raise abandoned nestlings.

Crop Milk

Pigeons and doves depart radically from other birds when it comes to rearing their chicks.  Rather than providing them with insects or fruit, breeding adults produce a semi-solid nestling food known as pigeon milk or crop milk.  While not related to mammalian milk, there certainly are some parallels.

The “milk” is secreted from the lining of the crop, which is a food storage organ located at the end of the esophagus (base of the throat) of most birds.  It is higher in protein (38%) and fat (58%) than both cow and human milk, and allows for very rapid growth.  Crop milk also contains several vitamins and minerals, and is produced by both males and females.

Birds in several other families have also evolved a milk-like nestling food.  Interestingly, that produced by Flamingos contains red and white blood cells.

Foster Parents

This is all very interesting, but the unique nature of crop milk renders it difficult to duplicate.  Consequently, orphaned pigeons and doves can be troublesome to hand-rear.

In fact, at the Bronx Zoo I used Ring-necked Doves as “foster parents” for chicks of the highly-endangered Pink Pigeon…this proved far more effective than hand-rearing.  By the time the Pink Pigeon squabs were ready to fledge, they were twice the size of their foster parents.  I still do not understand how the little Ring-necks produced so much food (I was working on a “double-clutching” experiment at the time.  The first Pink Pigeon clutch was pulled, so that the female would produce another batch of eggs.).

Artificial Crop Milk

Columba livia 22 daysIf you need to raise a squab and lack a foster parent, I suggest contacting a licensed wildlife rehabilitator (please see the National Bird Rehabilitatiors for help in locating someone).  Squabs feed in an unusual manner, making it quite easy for beginners to introduce formula into the trachea rather than the esophagus.

Folks with some experience may wish to try preparing their own crop milk.  A formula known as MacMilk has proven very useful.  It contains, among other ingredients, yogurt, egg yolk, baby food and cod liver oil.  Please see the article below for instructions on its preparation and use.

Commercially prepared crop milk replacements are also sometimes available…check the National Pigeon Association or similar organizations for leads.

I believe that I was born with an intense interest in animals, as neither I nor any of my family can recall a time when I was not fascinated by creatures large and small. One might imagine this to be an unfortunate set of circumstances for a person born and raised in the Bronx, but, in actuality, quite the opposite was true. Most importantly, my family encouraged both my interest and the extensive menagerie that sprung from it. My mother and grandmother somehow found ways to cope with the skunks, flying squirrels, octopus, caimans and countless other odd creatures that routinely arrived un-announced at our front door. Assisting in hand-feeding hatchling praying mantises and in eradicating hoards of mosquitoes (I once thought I had discovered “fresh-water brine shrimp” and stocked my tanks with thousands of mosquito larvae!) became second nature to them. My mother went on to become a serious naturalist, and has helped thousands learn about wildlife in her 16 years as a volunteer at the Bronx Zoo. My grandfather actively conspired in my zoo-buildings efforts, regularly appearing with chipmunks, boa constrictors, turtles rescued from the Fulton Fish Market and, especially, unusual marine creatures. It was his passion for seahorses that led me to write a book about them years later. Thank you very much, for a complete biography of my experience click here.
