Montana Birding Weekend on the Prairie

If you would really like to get an experience birding on some of the best remaining prairie in North America here is your opportunity. This is a fund raising event for the Nature Conservancy of Montana and promises to be a great weekend (Click on the image below to enlarge).

More Grouse

A few more grouse photos until I get my computer back from the repair shop and can have a bit more time to actually compose a decent post. First I had the Sharptail Grouse, then the hybrid grouse, now it is time for the big guys - the Greater Sage-Grouse.

More Hybrid photos

Frankengrouse

This morning I surveyed a lek and saw this.

This hybrid Greater Sage-Grouse/Sharptail Grouse had been found at this lek last year and I made sure I got out to see it this year. It was very interesting watching the behavior of this bird compared to the sage-grouse he was hanging out with.
I could hear him in the dark before I could see him although the strange garbled sound was merely something different at that point. As the light got better I was able to watch him roam around the lek unchallenged by the sage-grouse as he chased around to where the female grouse were arriving. He was ignored by both the male and female sage-grouse as he strutted around until he stepped over some invisible line and was promptly thumped by one of the male sage-grouse.
His plumage was an interesting mix of both species. The breast feathers of his upper breast had the dark arrowhead pattern of a sharptail, but puffed out and looking spiked like the worn feathers on the breast of a sage-grouse without the yellow cervical apteria. There was no really apparent purple apteria on his neck but the neck feathers were dark and appeared splayed to where the apteria should be. The overall plumage was much like that described for two hybrid specimens previously described in Montana (Eng 1971).
His display was an interesting mix of behaviors to match his plumage. He began his display with a half-hearted foot stomping while leaning forward like a Sharp-tailed Grouse but then he stood up and leaned back to pull his wings along his side like a sage-grouse. His vocalizations were a short choking gurgle. He also tried to chuckle like a sharptail but that sounded off too.
He certainly tried hard. He displayed in earnest all around the lek, but no one seemed interested. He was at least able to bully some of the younger sage-grouse and I watched in drive off at least one individual a few times.



My friend Krissy thought the Frankengrouse label was a bit harsh and suggested I should call it "Pat" but that reference implies gender confusion and this bird was certainly all male - a mish-mash of parts and misunderstood so I am sticking with Frankengrouse.

Ah, April!

As much as Julie hates April, I really like it. It is the month when the grouse really start dancing and I get a good excuse to get out of office and actually be a biologist again. The early morning stuff is a bit of a drag but watching the sunrise more than makes up for it. And getting to watch the grouse.
This morning I headed out to do some Greater Sage-Grouse lek surveys. It was another gorgeous morning and one lek I surveys was full of birds, so much that they had spilled out into a new area. It looks like from our early surveys that the number of displaying males are up quite a bit from last year.





This female grouse was hiding out in the grass near the lek. I think I observed more female grouse on the leks this morning than I have in all my previous years. This is usually about the week of peak female attendance at the leks and it certainly seemed like I caught it about right this year.


On the way home I found a Short-eared owl was hanging out in a CRP field.

More Sharptails

Last night I set my pop-up blind near the Sharptail Grouse lek I had scouted that morning. Then I hoped the wind wouldn't come up during the night and send it off to points unknown. As I made my way across the prairie this morning in the early pre-dawn light, I could tell that hadn't happened and my blind was just as I had left it the night before. I had to hurry up the low hill to beat the fast approaching dawn and the eastern horizon was already showing the pale bruised colors signaling the approaching sunrise. No birds flushed from the lek when I unzipped the blind and settled in but within a few minutes I could hear birds displaying on the lek in front of me and within a few minutes more they were displaying all around me.



I settled in and waited for the sun to break the horizon and provide me with enough light to take some photos. The wait gave me lots of time to just watch the birds displaying. I could hear the chuckles, growls, and grouse gobbles in the areas around the blind I couldn't see and I knew the males were facing off with each other because the birds in front of me were doing the same thing.



After settling the stare down one of the two would notice another male approaching his particular chunk of turf and he would dash over to settle the dispute.








Occasionally I could here the flash of wings and the feathery thwacks as a scuffle broke out. Then I would hear the sound of approaching flight from the incoming females and then the dancing would begin in earnest. It sounded like an unorganized drum roll of padded drumsticks on tiny snare drums, and when they were close, I could hear the purple air sacs popping as they displayed.



The first photos were bluish before the sun cleared the horizon and then the gold sunrise lit the birds up. But only for a few minutes before the sun slid into the scattered clouds overhead.









There was a lot of dancing early on but then as the females stopped coming to the lek and the day got longer, the males spent more time staring at each other rather than dancing. Occasional fights would break out but for the most part they were done dancing. Some even appeared tired and would stop and settle in for a quick shut eye.



Or a scratch.



Or a stretch.



About 8:00 am they were all done and they quickly departed as a group over the hill.

Sharp-tailed Grouse

This morning I had intentions of getting up early and going back to the Sharp-tailed Grouse lek I visited last week. It just didn't happen. I was able to get up early enough to check out a lek site that I hadn't been to in a number of years and found a good number of birds there.



After a week of traveling and meetings I was certainly ready to have some time out, but I had to get back early for a fireman meeting (new truck!) and then take care of the boys for the day. Tomorrow though..
