Smith (AOS), Ben Smith (BSm), Rebecca son's at Greeley, Weld 9 Jun (J. Karr, S. Manwar- ing) and Barr 2 Jul (TF) and an incredibly rare summer Taverner's at Boyd Lake, Larimer 4 Jun (CS). Out-of-place Wood Ducks in Colorado included singles in the mountains in Chaffee, Teller, and Park and a female with a brood of 5 in Elevenmile Canyon, Park 9 Jun (DSu). In Wyoming, Wood Ducks continued to demon- strate that the species may be more regular than rare in Jackson Hole, Teton, where there were seven reports of 1-3 from fve valley locations 9 Jun–27 Jul (m.ob.). Mexican Duck genes con- tinue to be found in Colorado, with Montezuma being the focus this season. A male Mallard x Mexican Duck hybrid was at Denny Lake 4 Jun, and 2 were at Totten Reservoir 5 Jun, but a fe- male Mexican Duck photographed with brood in tow at Totten Reservoir 5 Jun (all SGM) pro- vided the frst confrmation of breeding in the Region. Estimates of 40 Blue-winged Teal, 50 Northern Pintails, and 60 Green-winged Teal at Carmody Lake, Fremont 29 Jul (AL) all made for record summer eBird counts for Wyoming. Redheads are considered very rare breeders on Wyoming's e. plains, so the 16 at three differ- ent Goshen Hole locations, Goshen 10 Jun, and a single there 23 Jun (SB, LM), are of interest. Ring-necked Ducks are rarely encountered in summer in Wyoming away from their high- elevation breeding areas in the nw. and s.; this year's reports included singles at Bump Sullivan W.H.M.S., Goshen 10 Jun (SB, LM); Keyhole Dam, Crook 23 Jun (J. Blakeman); and Johnson 16 Jun (Bethany & Brooke Nelson). Seven were in the Big Horn Mountains, Big Horn 16 Jul (M. Robbins), where summer status is a mystery, while an estimated 50 at a roadside pull-off near Alum Creek, Yellowstone, Park 11 Jun (M. & S. Kuzio) provided a Wyoming record sum- mer eBird tally. Providing just the ffth Colorado summer report of the species, a male Greater Scaup was noted at LUNA Reservoir, sw. Weld 8 Jun (SGM), while pairs at Meeboer Lake, Albany 15 Jun (SB, LM) and at Rock Cut Pond, Uinta 20 Jun (frst latilong record; ph. MF) provided just the ffth and sixth Wyoming summer re- cords. Buffeheads are very rarely encountered grants, breeders, oversummering nonbreeders, wanderers, early fall migrants, enigmatic occur- rences, and outright rarities, and this summer was not an exception. Such phenomena were, perhaps, best illustrated in Wyoming by Stilt Sandpiper, possible second breeding record of Cattle Egret, Greater Scaup, Lesser Black- backed Gull, Sanderling, Western Screech-Owl, and the state's second Eastern Wood-Pewee, re- spectively. In Colorado, the list might include Greater Scaup, Common Ground-Dove, Greater and Lesser Yellowlegs, Common Goldeneye, Pa- cifc Wren, and the state's frst breeding record of Red-necked Grebe. Widespread phenomena occurring in one or both states included contin- ued breeding range expansion of Black-chinned Hummingbird, Least Flycatcher, Bushtit, Blue- gray Gnatcatcher, and Lesser Goldfnch, while those species exhibiting more modest expan- sions included Willow Flycatcher, Ovenbird, and Clay-colored Sparrow. Abbreviations: Barr (Barr Lake and S.P., Ad- ams); Crow Valley (Crow Valley campground, Pawnee N.G., Weld); Goldeneye (Goldeneye Reservoir, Goshen, WY); Plains (plains of Colo- rado); Prewitt (Prewitt Reservoir, Washington unless noted); Table Mountain (Table Mountain Wildlife Habitat Management Area, Goshen, WY); Tamarack (Tamarack Ranch S.W.A., Lo- gan); West Slope (w. of the Rockies, Colorado); Yellowstone (Yellowstone N.P., Park/Teton, WY). Due to reporting biases, all locations can be assumed to be in Colorado except that each Wyoming location is noted as such the frst time noted. Only the observer(s) initially fnd- ing and identifying cited records are identifed here. Undocumented reports from Colorado of Colorado B.R.C. (C.B.R.C.) review species that we deem correct are summarized at this report's end. Thanks to Doug Faulkner and Ann John- son for providing C.B.R.C. information. WATERFOWL THROUGH IBIS Summer Snow Geese were noted in Logan, Phil- lips, and Sedgwick (m.ob.), but much rarer were Cackling Geese, including presumed Richard- Tony Leukering Matt Fraker –––––––––––––––––––––––––––––––––––––– J une provided a distinct temperature gradi- ent in the Region, ranging from below aver- age in the n. half of Wyoming through near average in southern Wyoming and the north- eastern quadrant of Colorado to above aver- age in the rest of Colorado. July also exhibited a gradient, but in the perpendicular direction, with the eastern and central parts of both states being near average, while the western bits of both were above. Wyoming started the season with essentially no drought categorization, but by the end of the season a fnger of moderate drought (bordered by abnormally dry) had crept into the south-central part of the state. Colorado saw moderation in its various drought categorizations, with the northeastern quadrant being released from all drought categories dur- ing the season. Southeastern Colorado, which began the season under drought categorization ranging from severe through extreme to ex- ceptional, saw the extent of all three categories reduced in extent but not eliminated. Most of the rest of southern Colorado remained under abnormally dry or moderate drought conditions by the end of the season. Summer is a particularly interesting season due to the incredible mix of late spring mi- Colorado & Wyoming
