Wyoming had a banner Swamp Sparrow fall with singles seen 10 Sep at EKW, Natrona (ZH), 15 Oct in Albany (CP), and 18 Oct in Cheyenne, Laramie 18 Oct (CG) bringing the state's fall record total to 10. Wyoming's second modern October report of a Western Tanager occurred 10 Oct in Laramie, Albany (SB). Wyoming's sixth fall Northern Car - dinal, and the first away from the Casper area, spent the season in Torrington, Goshen, from at least 14 Aug–3 Oct (KA, ZH). An Indigo Bun - ting at WHR, Laramie 6 Sep (TF) provided Wyo- ming's second modern fall record of this species. Great-tailed Grackles first began showing up in Wyoming annually during 2012 and have been seasonally increasing ever since with the fall of 2015 presenting a record number of reports (nine) and birds (48) including a report both late and large of 15 birds 29 Oct near Laramie, Alba - ny (CB). Wyoming's fall White-winged Crossbill presence was decent again for the second year in a row, with five reports involving eight birds ranging from 3 Oct–12 Nov (m.obs.). Common Redpolls also gave Wyoming a solid showing with 12 reports involving 88 birds from 26 Oct– 25 Nov (m.obs.). Lesser Goldfinches away from their typical fall haunts in the south and SE of Wyoming were found in Washakie with two there 3 Aug (CJG) and a single 12 Aug (SH), while six in Green River, Sweetwater 3 Nov (JK, ph.) made for a very rare November report for the state. enne, Laramie 13 Oct (JA-R) and in Washakie 14 Oct (SMc). The Wyoming White-throated Sparrow fall passage was marked by seven re - ports involving 10 birds from 14 Sep–29 Nov (m.obs.). A Savannah Sparrow documented 19 SA During the third week of August, lights from an oil rig in an area that will remain undisclosed caused a flight to exhaustion of several species, possibly due to smoky conditions in the sky that evening. A Wyoming Fish and Game employee (who also will remain anonymous) was invited by the workers to come and assess what died during the flight. The employee found: 10 Eared Grebes 24 Wilson's Warblers 4 MacGillvray's Warblers 1 Yellow Warbler 1 Cassin's Vireo 2 Chipping Sparrows The workers had not experienced this phenomenon before, and the employee recommended turning off the lights if they ever did see such a flight in the future, which they were wiling to do. Unfortunate - ly this event demonstrates that even in the remote wilderness of Wyoming, migrating birds can still find lethal distractive threats. recorded, representing above-average fall totals. Two Black Scoters, not annual, were a great find in Ravalli, MT 19 Oct (ph. ER). Long-tailed Ducks were unusually scarce, with only 1-2 at Browns L., MT 31 Oct–4 Nov (ph. NK, NS). A Mountain Quail reportedly heard at L.P. 14 Oct (JC) was exciting, because this Regionally rare and sensitive species was considered extirpated in sw. Idaho several decades ago. Highlights of the season included single Red-throated Loons at Browns L., MT 31 Oct–4 Nov (ph, NS, CWo) and Flathead, MT 3 Nov (ph, CH). A seasonal average of 7 Pacific Loons were reported. A Brown Pelican that strayed to L. Pend Orielle, Bonner, ID 11-14 Nov (ph., †TM) will provide Idaho's second record. A third record for Idaho was furnished by a Little Blue Heron at Boi - se 25 Oct–20 Nov (RLR, m. ob.). Extralimital Green Herons visited the Gem State at Kuna 25 Sep (ph., †MR) and near Boise 11-12 Oct (†LA). Rare American Golden-Plovers came through w. Montana, with 2 in Lake 10 Aug (CH, BR) David Trochlell –––––––––––––––––––––––––––––––––––––– T he Region experienced a fall season with fairly average precipitation, but this was accompanied by unusually warm temperatures in lower elevation areas through Idaho & Western Montana October and cooler than usual temperatures in November. Evidently birds responded to the prolonged mild weather by delaying their passage through the Region, causing many to linger to record-late dates. Arguably waterfowl were most profoundly affected, since lakes and reservoirs remained ice-free until quite late into the fall. Despite the vagaries of the weather, the season will be long remembered as the most eventful season for rare birds in memory, as evidenced by an incredible 20 that warranted boldface type in this report. WATERFOWL THROUGH JAEGERS Greater White-fronted Geese put in an unusu- ally good showing in w. Montana, with small numbers seen at Harrison Res. 23 Sep (HC, LAH, JP) and Cottonwood Res. 27 Sep (NB). Routinely scarce in autumn, Cackling Geese were notable in Lewiston, ID 14-27 Nov (KCa, CL) and Lake, MT 17 Nov (PR). A total of 12 Surf Scoters and 12 White-winged Scoters were
