This spring I have been out capturing images of a couple different species of grouse. In my last column I wrote about the Greater Prairie Chicken, a species of bird that was once widespread and numbered in the millions and is now barely hanging on and extinct in much of its former range. This time I am looking at the Sharp-tailed Grouse.
Once again, I found myself getting up at four a.m., packing up what I will need for the morning and heading out to my old truck in the dark. A short drive later, I arrived at the location where I would find the second grouse species of the spring. When I opened my truck door, I could immediately hear several male Sharp-tailed Grouse (Tympanuchus phasianellus) calling in the dark.
After a short walk, I arrived at the location. I needed to assess approximately where the sun would be rising so I could place my chair blind in the best location with the sun at my back. This will provide the best light on the dancing grouse when the sun rises. Working quickly, I set up the chair blind and set up the tripod and mounted the 600 mm lens and camera.
I covered up and waited in the dark for the birds to arrive and the sun to rise. Within one minute I could hear and start to see the first of the Sharp-tailed Grouse walking and flying up to the dancing ground. The dancing ground, also called a lek, is typically made up of short grass vegetation. A lek is a communal area in which two or more males will gather and perform a courtship display. This isn’t limited to grouse species. Many species of birds, insects and mammals use a lekking performance area when it comes to mating. The grouse are just the most well-known species for using a lek.
On this particular morning, I counted 25 male Sharp-tailed Grouse that came to display on the lek. The males would pair up and face off. Within the lek are micro territories with the most dominant male at the center and satellite males surrounding the dominant one. The least dominant males are on the outer edge of the circle.
The most complex and fascinating of the males display is the “tail rattling” or dancing display. Each male leans forward and lifts a set of feathers on its neck to expose a pinkish to purple patch of skin. It cocks its tail feathers upwards, with the undertail feathers, called tail coverts, exposed and for maximum visibility. The male then starts a series of rapid short steps, about 18 to 20 per second, causing him to move forward in a curving or arching direction. At the same time, the male vibrates its tail, producing a clicking or rattling sound with an associated scraping noise created by scraping overlapping tail feathers. It sounds like a baby rattle. The best part of this is, all the males perform this stepping and tail rattling display at the same time, so what you see is what looks like a bunch of windup toy birds spinning in circles and at the same time it sounds like a snake pit filled with rattle snakes.
For the next three hours I sat in my blind capturing images and video of these amazing birds, all along marveling at the intricacies of their behaviors while capturing the strength and beauty of the amazing Sharp-tailed Grouse. Until next time…
