The other night while driving down from a great day of songbird banding, hawk watching, and trapping at Intermountain Bird Observatory’s Lucky Peak Migration Site, my friend Tempe Reagan and I came upon a number of Common Poorwill sitting in the road. I’ve had the experience of flushing “Goatsuckers” from dirt roads before, but I’ve never tried taking any photographs.

When we spotted another bird I slowed the truck early and slowly crept forward, pushing my luck for a better look. After I was nearly too close, I stopped the truck and slowly opened the door. Quietly I crept to the front of the vehicle and began taking photos. The bird seemed non-plussed by my movement, so I decided to push my luck further. I got low to get a proper angle of the bird, and soon found myself on my belly almost too close to the bird to take any photos.

I think Tempe was amused at the sight of me laying in the dirt road. I’m happy she took the photos and was willing to share, because it shows how tolerant these birds can be. I’ve heard stories of folks walking up to poorwills and nighthawks on dirt roads, being very quiet and careful, and capturing the birds before they could fly. I’ve never done this myself, but the ability to get photographs is good enough for me.

Although the truck lights seem ultra bright, they did not create much light for my camera to work with. I cranked the ISO and lowered my aperture and shutter speed as low as possible. I came away with some neat photos, although next time I bet a short video clip would be even more satisfying.

Intermountain Bird Observatory’s Long-billed Curlew Study

I was fortunate to tag along with Jay Carlisle and the IBO crew yesterday afternoon to trap and outfit a female Long-billed Curlew- Numenius americana, with a GPS transmitter. IBO has been tracking Curlews for a little over a year now, with the focus of understanding their movements and why there has been a general population decline.

This is a great project, headed by a great institution. I encourage everyone to take a moment to learn about the effort and consider supporting the work of IBO.

The Long-billed Curlew is an exceptional bird. Let’s do our part to make sure it has a future in the changing west.

Sharp-tailed Grouse Lek

by Bryce W. Robinson

 

Yesterday, I had the privilege of getting up at 4 AM to join Jay Carlisle and Heidi Ware on a trip to visit a Sharp-tailed Grouse lek in western Idaho. We arrived on the lek before sunrise, just in time to hear the beginning dances of the lekking grouse. As the sun rose the grouse surrounded us, chucking in unison and stamping their feet.

If you’ve never been to a Sharp-tailed Grouse lek, you must. It is a bizarre performance as the birds face off with a nemesis to exhibit their fitness and attract the attention of a lady.

The peculiarity of this display is reason enough to ensure that open natural landscapes, such as the sagebrush steppe in western Idaho is preserved. Spread the word and the images of natural wonders such as these grouse, so that even those not so interested in wildlife will recognize the benefit of conserving the wild world.

A Communal Roost of the Great Horned Owl

by Bryce W. Robinson

 

I’d like to share this video of a solitary roosting Great Horned Owl to introduce a story and celebrate a career goal accomplished for both Caitlin Davis, and myself.

In December 2012, Caitlin and I were conducting Golden Eagle surveys in the west desert of Utah. One evening on our survey route near the border of Nevada and Great Basin National Park, we came upon a roosting pair of Great Horned Owls. These owls sat in a small string of trees about 30 m in length. Soon after we discovered the roosting pair, we noticed an additional four owls in the same tree line. A total of six owls sat together in close proximity, and soon after we counted the birds, I knew the significance of what we had found.

Because I knew that Great Horned Owls are extremely territorial, I looked into the literature hoping to find any reports of similar roosting behavior. After what seemed to be an exhaustive search, I had found no reports of any communal roosting behavior for the Great Horned Owl, or any other Bubo species.

I discussed the idea of reporting the findings with Steve Slater, Shawn Hawks, and Markus Mika at HawkWatch International. They were supportive of the idea, so with little hesitation I wrote a short report of the roost and submitted it for publication to the Journal of Raptor Research.

The report was accepted, and has now been published in the latest issue of the JRR. Caitlin and I are extremely grateful to everyone who helped us get the word out in the proper fashion by talking out ideas, and revising the manuscript. It was a fun process, and I look forward to repeating it again in the future.
