2nd Top Post of 2012January 3, 2013
This post was another favorite for 2012. It is the study of a Bird Feather. Just like a human hair, the individual strands (hairs) are linked together with minuscule hooks to form a solid feather. Amazing stuff!
Recent discussions with Dr. Bob, and the excessive heat these days, has sparked me to re-study how Birds deal with this extreme heat of summer. Not having sweat glands, they use a number of techniques to cool themselves down. The term for what Birds do to cool-off is called Gular Fluttering. You can read more on this specific subject with Dr. Bob’s discussions on the Audubon Society Blog, at: http://archive.audubonmagazine.org/ask/ask0007.html
All this talk of Birds dealing with the extreme heat of summer, sparked me to redo a PDF file we had on the web site. The file was a study of the details of a Bird’s Feather. A nice close-up and examination of the make-up of an individual feather.
I have always been intrigued by Bird feathers. Their shapes, colors and delicate yet many uses. I have collected feathers since I was a young Scout, and never stopped for the rest of my life.
I hope you find the Bird Feather study interesting and get a better understanding on how a Bird uses it’s various feathers to fly, maneuver and keep warm & cool through the different seasons and temperatures.
