Blissfully Yours

The word “bliss” inspired today’s photo!  I decided to share with you a photo of my bird Siri, napping on her perch. She was so “blissfully” unaware that I took my phone and layed it right near the top of her head, and she didn’t even stir.  Isn’t it amazing how birds can sleep perched like this and not fall?  There is a wonderful article which explains the fact that their legs and feet work on something akin to a pulley system.  When their legs are out and extended (as they often are before landing), their feet open.  However, when they are in a more crouched position, their feet automatically close and can “clamp” onto things.  This works very well for raptors when they extend their legs to reach for prey and then pull the catch close, so it can be held tightly.  Click here for that article, if you’re intrigued enough to learn more! (Note: there is some evidence that not every single bird species has this “pulley system” in place.  The European Starling was found to be an exception, as you can read in the article I mentioned)
