May 4-11, 2002The leader and creator of the tour is Bill Clark, also known as William S. Clark, co-author of A Photographic Guide to North American Raptors and other useful books. Our vacation photographs are not in his world class category but we hope they will give you a tiny taste of the wonders that await you on a visit to this unique area known for its very high concentration of nesting raptors, including hawks, falcons, eagles, and owls.It's a shame we have to say this, but please note that our photographs are copyrighted. Of course you are always free to link to our photographs and to our trip report, but please do not use our photographs or words without our permission. Thanks!The Snake River Birds of Prey National Conservation Area is said to be home to the largest concentration of nesting raptors in North America. I don't know where you would see more Prairie Falcons. The raptors we observed included Turkey Vulture, Osprey, Bald Eagle, Northern Harrier, Sharp-shinned Hawk, Cooper's Hawk, Swainson's Hawk, Red-tailed Hawk, Ferruginous Hawk, Golden Eagle, American Kestrel, Peregrine Falcon, Prairie Falcon. Owl species included Barn Owl, Western Screech-Owl, Great Horned Owl, Burrowing Owl, and Long-eared Owl. Two other possible species are Goshawk and Short-eared Owl but we didn't luck into an encounter with either of these species on our trip. My total number of bird species was 126, and most of the folks saw a couple more species, because I'm a little slow sometimes. Since this was my first birding trip to the Northwest, I added many new "lifers" to my list. To check out my complete list of 126 species, click here. ![]() Black-billed Magpie by Roger Williams, copyright 2002, all rights reserved However, a bald list of species does not convey the excitement of observing the courtship, nest-building, and chick rearing of so many powerful birds. We had a fascinating glimpse into the private "at home" personal lives of these birds of prey. There was always a lot of action, as small birds defended their territories by chasing away larger birds that they viewed as threats to their young. For instance, a male Northern Harrier was being pestered by Red-winged Blackbirds. He captured some prey, presumably to bring to the female. As he was flying, he suddenly dropped the prey and attacked a Swainson's Hawk that had come into view. The Harrier won that round but on another day, we observed a Raven steal an egg from the Harrier nest. The day after that, the Harrier was busy building a new nest in a nearby tree. Whether it was a Long-billed Curlew chasing an American Raven or a Prairie Falcon chasing a Great Horned Owl and then a Red-tailed Hawk, it seemed that somebody was always getting territorial with somebody else!

May 5, 2002The first day in a new area is always a big one. We checked the area around Swan Falls, where we saw the Great-Tailed Grackles who recently invaded the area, and then took a float trip down the Snake River to see the breeding cliffs. There were Prairie Falcons nesting in the area, a Western Screech Owl peeking out of a nest box at eye level, a Great Horned Owlet loitering in the cliffs, and much, much more. New life birds included Lewis' Woodpecker, Prairie Falcons, Western Grebe, Chukar, Lazuli Bunting, probably more but I haven't organized my old bird lists yet.
There were plenty of Swainson's Hawks pairing up and working on nests, so we had a great opportunity to study the different plumages displayed by these wonderful birds. For dinner we had our Cinco de Mayo celebration at Case Ole complete with some very strong margaritas!
May 6, 2002We visited many Swainson's Hawk and Ferruginous Hawk nest sites.
May 7, 2002Today was the coldest May 7 in Boise, Idaho since records have been kept. There were even snow flurries with large fluffy white snowflakes falling on our intrepid crew. But we couldn't be stopped -- we forged right ahead with our viewing of multiple raptor species. We observed Osprey nesting platforms, American Raven stealing an egg from a Northern Harrier, a Prairie Falcon catching and eating prey, and Golden Eagles hunting and being "mobbed" by smaller birds as they put on a real show for the tourists! We had dinner once again at Table Rock, where a radio station was offering a great beer promotion.
May 8, 2002We visited the World Prey of Bird Center, which started out by breeding Peregrine Falcons. Now that these birds are recovered, they've gotten into breeding California Condors and educating the public about other birds of prey.
A big highlight of the day was the baby Great Horned Owl with his mother hovering (well, perched actually but metaphorically hovering) in the background.
May 9, 2002Thursday started with a "bang" when we observed the Peregrine Falcon pair who live in the skyscraper across the street from the capitol building. The first day we observed them, we pulled our van up to the capitol building, despite the barriers. Don't do that. A lot of western capitols received truck bomb threats after September 11, and they had to put up barricades and get security guards to chase people off. This morning, we found a better place to park, and it was well worth it. Both male and female were present. We observed the birds copulating and then the male directed the female's attention to a food cache he had put over the nest box. She finally got the idea, and we could see the feathers flying as she feasted on well-aged Mourning Dove.
Today we headed up to Lake Cascade for a breath-taking, if sometimes windy experience.
Red-naped Sapsuckers were working very hard very close to the road:
We also saw four adorable baby foxes by the roadside, as well as a couple of adult
ones here and there along the way:
For dinner, we tried The Grape Escape, a wine-tasting bar near the capitol with live music and a great selection of wine.
May 10, 2002Back into the Snake River Canyon we go in search of owls and other raptors. Did you ever see a Barn Owl nesting in an actual cliff instead of in a barn or an old broken-down radar installation or something of that sort? Hey, we saw two!

As we entered the Western Screech Owl nesting area, an unexpected Great Horned Owl came swooping in very close, with a Prairie Falcon hot on its heels. Having chased off the owl menace, the Prairie Falcon then amused itself by harassing a pair of Red-Tailed Hawks which were trying to enjoy their courtship flight. It is always inspiring to watch a much smaller bird fearlessly dealing with any perceived threats to its breeding territory. Dinner at Table Rock again.
May 11, 2002The tour was officially over but we didn't have to get to the airport until noon, so we took some time in the morning to say goodbye to the Mallards that live in the University Inn swimming pool:
