N O R T H A M E R I C A N B I R D S 94 til at least 28 Aug (B. Rodrigues), and one at Madera Canyon that was last detected 15 Sep (m. ob.). A new Plain-capped Starthroat was discovered in Patagonia 9 Sep (ph. R. Moore), and remained until 19 Oct; this species has be - come a rare but regular late-summer visitor to canyons in se. Arizona. Several Lucifer Hum - mingbirds were detected at usual known loca- tions, such as Ash Canyon and Portal, but one at a feeder at Tubac 14 Sep–3 Oct (ph. S. Carna - han, C. Smith) was of note because it was well away from any suspected breeding locations, while one at a feeder at Bisbee 26 Oct (SW) was considered late. Outstanding was two different Ruby-throated Hummingbirds in se. Arizona this fall, representing only the fourth and fifth records for the state; one male was at Whitetail Canyon in the Chiricahua Mts., 24-27 Sep (RT; ph. J. Lewis), and another imm. male was at Bisbee 26 Oct (ph. SW). Violet-crowned Hum - mingbirds have been known to disperse n. after the breeding season and often show up at feed - ers; singles were found this fall at Catalina 17 Sep (R. Bowers), Tucson 21 Sep (R. Modica, J. Conway), and Oro Valley 4 Oct–3 Nov (ph. K. Rishor). A White-eared Hummingbird at Miller Canyon was last reported 21 Aug (BJ), while another was in Korn Canyon on the w. side of the Huachuca Mts. 25 Aug (T. Helentjaris). GALLINULES THROUGH FALCONS A Purple Gallinule discovered at Granite Ba- sin L. 17-20 Sep (ph. CT, BP, D. Rasmussen, S. Hosner), provided the northernmost record for the state. A high, early count of 145 Sand - hill Cranes was obtained at Cibola 11 Oct (L. Story). An American Avocet at Black Mountain Power Plant, Golden Valley near Kingman, 27 Nov (ph. M&P Brock) was very late for n. Ari - zona. An above average 7 Black-bellied Plovers were found around the state this fall, with one at Vicksburg 8-9 Aug (LHa; ph. DVP), one at Ehrenberg 21 Aug (EH), 2 at Willcox 3-4 Sep (REW), one at Wellton 26 Sep (ph. JCo), an - other at Willcox 26-28 Sep (J. Smith, R. Beck), gos Park, Glendale, 20 Nov (ph. L. Hoeniger). Up to three Mexican Mallards were at the n. end of L. Havasu 1 Aug–4 Oct (LHa, DVP), one was at Rotary Park in Lake Havasu City 10 Sep (ph. LHa, DVP), and one was at Parker Dam 24 Oct–21 Nov (LHa, DVP); this form that breeds in southeastern Arizona and New Mexico has been spreading to the northwest, and has only recently become established along the Colo - rado River. A Blue-winged Teal at the n. end of L. Havasu 1 Aug (LHa, DVP) was considered early, as was a Northern Shoveler at Yuma 12 Aug (S. Hosner). A high count of 177 Redheads (including many ducklings) were present at the n. end of L. Havasu 1 Aug (LHa, DVP); it is only recently that Redhead has been established as a regular breeding bird along the Colorado River in w. Arizona. A high count of 292 Greater Scaup was obtained in Bill Williams Delta 21 Nov (DVP); this location has become the best location in recent years along the Colorado R. for wintering Greaters, a shift s. from the Davis Dam area, which was this species' stronghold in the state historically. One Greater Scaup was at Alamo L. 27 Nov (CS); it is casual at best away from the Colorado R. during fall and winter. A Surf Scoter was discovered along the Lower Salt R. at Pebble Beach 30 Oct–3 Nov (ph. R. O'Donnell), and another was at Patagonia L. 29 Nov (D. Cleary); this species is scarce in Arizona away from the Colorado River. The only record of Surf Scoter from along the river this fall was a single bird at Bill Williams Delta 21 Nov (DVP). A Black Scoter at Upper L. Mary, outside Flag - staff 7 Nov (JWi, M. Philippart, T. Blows) pro- vided one of the few records in the state from n. Arizona. The high count for the season of Red- breasted Mergansers along the Colorado R. was 13 at Bill Williams Delta 21 Nov (DVP). Gambel's Quail were reported more widely along the Arizona Strip in nw. Arizona than pre - viously; of interest were 15 at Salaratus Draw 18 Sep, 7 at Big Dike Res. 29 Sep, and 3 near Robinson Canyon 2 Oct (S. Langston). A single Horned Grebe was at Ashurst L. outside Flag - staff 17 Nov (ph. T. Linda); this species is ca- sual in Arizona away from the Colorado River. Individual Ruddy Ground-Doves were found at Oxbow Campground near Cibola 2-5 Sep (ph. J. Crawford), at Hidden Shores Golf course near Yuma 11 Oct–16 Nov (ph. CMc), at Sweetwa - ter Wetlands, Tucson, 7 Nov (B. Buck), and at Tolleson 25-26 Nov (WG, ph. BJ); this species remains annual in the state in small numbers, mostly during fall and winter. The Buff-collared Nightjar that summered at California Gulch was last reported 1 Oct (LH, M. Kehl). Three different Plain-capped Starthroats found during summer lingered into the fall, in - cluding one at Ash Canyon that was last seen 15 Aug (RBe), one at Portal that remained un - Gary H. Rosenberg –––––––––––––––––––––––––––––––––––––– T he fall was characterized by the continu- ation of several pairs of Rufous-capped Warblers that appear to be breeding in several canyon in southeastern Arizona; they may be going through a similar expansion as a resident in the state as Black-capped Gnat - catchers went through during the past decade. Some fine rarities were found, including Arizo - na's fourth and fifth Ruby-throated Humming- birds, northern Arizona's first Purple Gallinule, a continuing Tufted Flycatcher, and a number of fun warblers including two Golden-wingeds, two Blue-wingeds, a Blackburnian, a Yellow- throated, and a new Slate-throated Redstart. A few species that were once considered rarities in the state, such as Eastern Phoebe, Clay-col - ored Sparrow, and Painted Bunting, continue their expansion, and were seen in increasing numbers again this fall. I would like to take this time to thank Mark M. Stevenson for his many years of help writing the Arizona report, and making the information published herein as accurate as possible. WATERFOWL THROUGH HUMMINGBIRDS Five Greater White-fronted Geese were at Ci- bola 15 Nov (L. Arnold), where they are con- sidered rare. The Ross's Goose that was located in Yuma during the summer remained until 30 Aug (HD). Another Ross's Goose was at Alamo L. 26 Nov (ph. CS), where it has been reported infrequently. A Brant was a pleasant surprise at the Amado STP 16 Nov (ph. LH, J. Hays); there have been only 16 previous Arizona records, most of which have occurred along the Colo - rado River. Six Tundra Swans were at Alamo L. 25 Nov (ph. CS); this species is casual to rare in Arizona away from the Colorado River. Casual in the state, a Eurasian Wigeon was at Dos La - Arizona This Purple Gallinule was present at Granite Basin L. near Prescott 17-20 Sep 2015, providing the farthest north record for Arizona.
