V O L U M E 6 9 ( 2 0 1 6 ) • N U M B E R S 3 / 4 461 A R I Z O N A Burk); this provides a fifteenth Arizona record and the northernmost anywhere. Single Hood - ed Warblers were at 'Ahakhav Tribal Reserve near Parker 18 Apr (ph. J. Swackhammer), at Cibola N.W.R. 5 May (ph. C. Dodge), and at Las Cienegas 8 May (KK); this species contin - ues to be a very rare regular spring migrant in the state. No fewer than 15 American Redstarts and 7 Northern Parulas were reported state - wide, about normal for a spring. A male Chest- nut-sided Warbler was along Tonto Creek e. of Payson 16 May (T. Conlin, fide B. Ison), and a female was in the Chiricahua Mountains be - tween East Turkey Creek and Onion Saddle 20 May (ph. A. VanNorstrand); this species is de - cidedly rarer during spring than fall/winter. A male Black-throated Blue Warbler discovered in South Fork of Cave Creek Canyon 17 Feb was relocated 12 Mar and remained until 7 Apr (K. Morales, m.ob.), confirming local winter - ing. Only 2 Palm Warblers, rare to casual in the state, were reported: one at Sweetwater 3 May (L. Safford) and one along the Little Colorado River upstream from Cameron 12 May (CL). A nesting pair of Yellow-rumped Warblers at Ramsey Canyon 29 May (M. Phil - lips) was of interest, as this species is a local and rare breeder in the Huachuca Mountains. The Yellow-throated Warbler that wintered in Patagonia was again reported 21-23 Apr (R. P. Moore). A Fan-tailed Warbler was netted in Ramsey Canyon 31 May (ph. W. Leitner); this will establish a tenth Arizona record, many of which are from late May. Rufous-capped War - blers continued in Florida, Hunter, and Miller Canyons; this species appears to be establish - ing itself in the state as a resident, much as did Black-capped Gnatcatcher during the past de - cade. A singing male Slate-throated Redstart was at Soldier Trail, Santa Catalina Mountains 19-20 Mar (ph. PS; ph. AC, L. Hays, K. Mur - phy, J. Smith); there have been only 11 previ- ous records for the state, but this record repre- sents the fifth in the past three years. Botteri's Sparrows were detected at numer- ous sites in se. Arizona by early Mar, which Montosa Canyon, California Gulch, and near Patagonia. A late Ruby-crowned Kinglet was in California Gulch 22 May (DS). Two Eastern Bluebirds in Continental Wash 4 Mar (LH) were away from know breeding ar - eas in the state and thought possibly to be of the "eastern" (nominate) subspecies. No fewer than 9 Rufous-backed Robins were reported during the spring season, some lingering win - tering birds found previously: 2 were at Portal 13 Mar–12 May (S. Koenon, R. Stripper; ph. NMC, DJ), one was along Cienega Creek 25 Mar–6 Apr (MA), one was in lower Ash Can - yon 24-30 Apr (RBe; ph. S. Finnegan), and one was in Florida Canyon 24-26 Apr (ph. L. Beth). Individual Varied Thrushes, a ca - sual winter species in the state, were at Oak Creek Canyon 14 Mar (ph. J. Tanner), Bear Wallow, Santa Catalina Mountains 2-3 Apr (L. Figueroa, D. Touret; ph. J. Vogt), and Ajo 6 Apr (J. Veverka). Five Gray Catbirds were reported statewide, about average for a single spring. Brown Thrasher is a rare to casual visitor to the state; this spring, one that was discovered dur - ing the winter at Gilbert Water Ranch was last seen 27 Mar (m.ob.), one was in the Rincon Mountains 25 Mar–6 Apr (ph. PS), one was at Sedona 5 May (ph. J. Tanner), and one was at Becker Lake, Springerville 26 May (D. To - uret). A one-day-wonder Blue Mockingbird was photographed in lower Ramsey Canyon 21 May (ph. M. Reynolds), a fourth record for Arizona if accepted. Olive Warbler is another species expanding northward and westward, as evidenced by additional recent records from the Hualapai Mountains 6 Mar (DVP) and 12- 24 May (fide DVP). A Lapland Longspur and a Chestnut-collared Longspur were seen near the South Rim of the Grand Canyon 4 Apr (BG), both first local records. Another Chest - nut-collared along Stateline Rd., Portal 18 May (DS) was very late for se. Arizona. WARBLERS THROUGH FINCHES Ovenbirds were in Oak Creek Canyon 12-13 May (J. Grahame, T. Linda; ph. V. Nelson) and at Willcox 16-17 May (ph. M&L Jar - rett); this species is a rare migrant in the state. The Louisiana Waterthrush that wintered in Sabino Canyon was last reported 19 Mar (m.ob.), and the one wintering along the San Pedro River was also last reported 19 Mar (m.ob.). No fewer than 18 Northern Waterthrushes and 15 Black-and-white Warblers were seen during the spring statewide; both of these species have become rare regular migrants in the state. Quite exciting was the discovery of a singing male Cres - cent-chested Warbler at Granite Basin Lake, Yavapai 16-17 May (ph. CST, S. the Bill Williams River (Black Rail Marsh) 23 Mar+ (v.r. A. Eberly, J. Tobin, M. Lester); this individual was considered to be a continuing individual. A Tropical Kingbird was at Havasu N.W.R. 29 May (LHa); this species continues to expand northward and westward in Arizona. A pair of Thick-billed Kingbirds returned to Portal, w. of normal breeding areas in the state, 2 May+ (DS; ph. M. Decker). The only Scissor- tailed Flycatcher of the season, a bird that is ca - sual as a spring and summer visitor in the state, was near Lake Pleasant 31 May (ph. KR, CR). At least one and perhaps 2 White-eyed Vire - os were present at Portal 19 May–1 Jun+ (REW, K. Miller); this species has become more regu - lar in the state in recent years. Numerous Gray Vireos were reported as migrants this spring from a variety of "lowland" locations, and one in La Milagrosa Canyon, Santa Catalina Moun - tains 13-21 Apr (ph. PS) may represent a new breeding location. A Yellow-throated Vireo at Ramsey Canyon 25 May (ph. M. Meyers) was the only one reported during the spring; this species has become more regular in the state in recent years. No fewer than 10 reports of Hut - ton's Vireos were received from the Hualapai Mountains 6 Mar–14 May (DVP; m.ob.), con - firming this species' expansion into this moun- tain range as a breeding species. Elsewhere, one was along the Bill Williams River 24 Apr (K. Murphy), and 2 were nearby along the river 2 May (LHa); Hutton's Vireo has generally ex - panded northward and westward within the state. A Red-eyed Vireo, rare to casual in the state, was at the Cameron Trading Post 17 May (ph. C. Babbitt). A Purple Martin at Lake Havasu City 15 May (B. Willcox) was casual locally. A major push of Tree Swallows passed through the state along the L.C.R.V, with an estimated 500,000+ at Lake Havasu 8 Apr (DVP, LHa), and 1,200,000 estimated at Picacho State Rec - reation Area n. of Yuma 15 Apr (LHa); these are extraordinary numbers for the state! Late reports of Red-breasted Nuthatches at Patago - nia 27 Apr (D. & D. Hamilton) and at Tucson 5 May (J. Higgins) were likely late lingering win - tering birds. Six Pacific Wrens and 6 Winter Wrens were reported statewide, mostly in Mar and early Apr; both species have been found to winter in Arizona in about equal numbers, and we recommend using diagnostic vocaliza - tions to distinguish them. The Sinaloa Wren wintering along the Santa Cruz River near Tu - bac was last reported 23 May (m.ob.), and the one at Huachuca Canyon was last reported 3 May (m.ob.); both of these individuals have vanished and reappeared multiple times since their discoveries. Black-capped Gnatcatchers continue at all of the recent known breeding areas, including Florida Canyon, Proctor Rd., This Crescent-chested Warbler at Granite Basin Lake near Prescott 16-17 (here 17) May 2015 provided the fifteenth (and northernmost) record of this species in Arizona.
