What an honor it is to be in the company of mourning doves and to witness them enjoying the amenities in my rooftop garden, such as one of the water sources I provide.
Most birds drink by dipping their bill in water and throwing their head back to swallow. Pigeons and doves are able to immerse their beaks and can drink continuously (as seen in the next image of a mourning dove).
As you can see, the eye-lids of mourning doves are blue!
This is one of many facts that is discussed in both the digital (iBook and ePub) and softcover version of Words In Our Beak Volume One.
Moreover, Volume Two of the book series is now available! Both volumes one and two are in hardcover format (as seen below) and can be purchased any place where books are sold.
