CoBus Bird Breeding Atlas Counts

July 1 to July 21

CoBus has two groups out conducting BBS Counts. I am putting together trip reports of both groups. Information is partly reported hearsay and partly personal experience. Groups have included Bryan Ehlmann, Sue Ehlmann, Gary Weston, Richard Stevens, Gary Zeeto, Roger Danka, Bill Cryder, Jerry Petrosky, Randy Cross, and at times several others. A few birders have participated in both groups.

For those who have not heard, CoBus is planning to publish an addendum to the Colorado Bird Breeding Atlas II (Called BBS IIc). Plans are to publish this about 120 days after the BBS II is published.

For the sake of brevity, I will list locations of BBS IIc counts and any uncommon birds reported. A complete list would last for pages and pages. Look for BBS IIc. I will call groups Group A and Group B; rather than label #1 and #2.

And to catch up:

Group A (Bryan & Sue Ehlmann at the time)

June 11: Black Canyon Gunnison National Park (Northern Pygmy-Owl, Dusky Grouse)
June 12: Box Canyon (Black Swift)
June 13: Silverton (Calliope Hummingbird)
June 14: Yellow Jacket Canyon (Lucy's Warbler, Scott's Oriole, Black-throated Sparrow)
June 14: J Road Bridge (Black Phoebe)
June 15: Wildcat Canyon (Acorn Woodpecker); Lake Havilland (Williamson's Sapsucker, American Three-toed Woodpecker)
June 20: Uravan (Black Swift, Rufous Hummingbird)
June 23: Dry Creek Basin
June 24: Upper San Miguel Drainage
June 26: Norwood
June 27: Slick Rock (Black-throated Gray Warbler, Black-throated Sparrow)
June 28: Barkelew Draw (Grace's Warbler, Common Nighthawk, Ash-throated Flycatcher)
June 29: Beaver Park (Purple Martin)
June 30: Ouray (Eastern Kingbird)

Note: Recommended hours of birding per section are 20 to 40 hours. Most birders performed 20 hours on their block in one day. It was noted whether additional time would increase the number of species found. Travel time within a block was included in birding time. Birders kept their eyes and ears open for birds during their travel time. Several hours were spent on owling in each block.
