While visiting the San Diego Safari Park with my sister last year, I spotted these beautiful flamingos at sleep and/or resting with their heads laying on their back.
Looking at a wider shot I took of them, I also realized that some of them were sleeping in this uncomfortable position with only one leg on the ground and their other leg tucked just below their bodies.
Now I can sleep while in a sitting position, but there is no way that I can sleep standing up and on one leg.
One theory as to why Flamingos sleep this way is that it keeps them warm during colder weather. However, some experts have observed them to sleep/rest on one leg during warm months too. Bless their hearts. I guess only these beautiful birds truly know the reason why they sleep the way that they do.
