Mind. Blown.

I read a fact the other day that blew my mind.

I was reading an article on Audubon’s website called “Who Wins the Feeder War?” by Nell Durfee. In this article, Durfee explains about a new study in feeder hierarchy. The author then presents 5 “duels” you may observe at a feeder along with some facts about each bird. You can read the article at http://www.audubon.org/news/who-wins-feeder-war.

I am reading and enjoying this article and get to Mourning Dove vs. House Sparrow. I click on the Mourning Dove and read a really crazy fact. And I quote:

“Store large amounts of food in crop (record is 17,000-plus seeds in one dove)”

17,000-plus seeds?! Woah!! Mind blown.

So of course I needed to investigate this amazing fact further. I stumbled upon a Washington Post article from January 2012 called “Mourning doves: Gluttons of the bird feeder” by Patterson Clark (you can read that article here).

In one day, a Mourning Dove can consumes as much as 20% of their own body weight. In order to do this, they need to store food in a crop. A crop is a specialized area that is found in some bird species. It is an enlargement of the lower esophagus that aids in food storage so that the bird can move safely. The food will stay in the crop until the bird is ready to either pass the food into its stomach or regurgitate it to its young. In some birds, cells in the crop lining will help produce a “crop milk” that is rich in lipid to feed to their young.

It’s fascinating that this record-setting Mourning Dove fit over 17,000 seeds in its crop! The avian body is amazing. Mourning Doves love seeds and will happy devour as much food as possible from your feeder. They prefer platform feeders, ones with a perch, or just simple flat ground.

Next time you check your feeder, keep a careful lookout for the gluttonous Mourning Dove. They might try to eat you out of house and home using their crops!;-)

I am an avid birder, teacher, and nature lover. I primarily go birding in New Jersey and Pennsylvania, but love to travel. I am currently a biology student with interests in conservation biology, ornithology, and environmental sciences. My dream is to go birding in all 50 states.
