N O R T H A M E R I C A N B I R D S 42 O N TA R I O at Kenora, Kenora on 25 Sep (CJSM), fur- nishing just the fifth provincial record. Fish Crows, which just a few years ago were an extreme rarity and only expected in spring migration in the extreme sw., continue to increase with one bird present at Oungah, Chatham-Kent 26 Nov (PWD) plus 4 at Fort Erie, Niagara 15 Nov+ (NGM, m.ob.). Com- mon Ravens, spreading the opposite direc- tion of Fish Crows, are now so routine in s. Ontario it seems like a waste to mention them, but one discovered at Holiday Beach C.A. 22 Oct (JMD) was noteworthy as Essex seems to be one of the last parts of the prov- ince where they are still unusual. There were not many noteworthy counts or dates of the common swallows in the province, with perhaps the exception being a count of 4070 Purple Martins near Leam- ington, Essex 16 Aug (JMBe) which, while high, was well below the estimated 30,000 last year around the same time. After a re- cord fall in 2012, Cave Swallows had been virtually absent with just one record during the past two falls, but they were again pres- ent in force with 14 reports totalling at least 40 individuals. These reports were as fol - lows: one at P.P.N.P. 7 Nov (JDV, JMBe, JLH, KJR), 3 at Kincardine, Bruce 12 Nov (JAT), 2 at Erieau, Chatham-Kent 13 Nov (BAM, SRC, GTS), one at Thornbury, Grey 13 Nov (LR), 4 at Oakville, Halton 14 Nov (m.ob.), one at Mississauga, Peel 14 Nov (m.ob.), 2 at Lurgan Beach, Bruce 19 Nov (MTB), 23 at several locations near Rondeau P.P., Cha- tham-Kent (m.ob.), and 3 at Oakville, Halton 20-24 Nov (m.ob.). It appeared as though there was a small Shuniah 20 Oct+ (PJT, DT), and Nipigon 10 Nov (RS, MS). There were no southward movements of Black-backed or American Three- toed Woodpeckers this fall. There was again only a single Gyrfalcon reported this fall, at the Thunder Bay wa- terfront, Thunder Bay 8 (SMA) and 22-23 Oct (BJM). There are always a few rarities in the fly- catcher department during autumn and this year was no different. A Say's Phoebe at Blenheim, Chatham-Kent was a highlight for many even though it was only present 17 Sep (JTB, m.ob.). The only Western King- birds of the season were at Courtright Ridge, Norfolk 6 Sep (L.P.B.O.) and Ottawa, Ottawa 27 Sep–4 Oct (m.ob.). After huge declines spanning the past 30+ years, Loggerhead Shrikes are now virtually never detected in migration, but one tagged with a Motus transmitter was detected re- motely when it flew by Bird Studies Canada's headquarters at Port Rowan, Norfolk 10 Sep (fide SAM); certainly an interesting way to add a species to a list! White-eyed Vireos were pretty scarce this fall with just two away from the sw.; one was at Mississauga, Peel 21 Oct (LSF, DRS) and another at Presqu'ile PP, Northumberland 27 Oct (PC, AH) marked just the third fall re- cord in the past decade. There were a cou- ple of very late vireo records in s. Ontario; the first was a Philadelphia Vireo banded at Long Point, Norfolk on 5 Nov (MAC) and the second was a Red-eyed Vireo at Oakville, Halton 12-16 Nov (RDMa, m.ob.). H.B.M.O. reported single-day highs for Blue Jays and American Crows with 35,690 on 10 Oct and 11,060 on 23 Oct, respec- tively. A long staying but well out of range Black-billed Magpie continued to frequent a feeder at Echo Lake, Algoma throughout the period. There was a Clark's Nutcracker other was in nw. Ont at Fort Frances, Rainy River 9 Nov (p.a., ADJC). On- tario birders keep expect- ing this species to finally break through, yet it is still a very rare bird. Even rarer, a Common Ground- Dove, just the fourth for the province, was at Sioux Lookout, Kenora 8-9 Nov (EDMB, EMEB). It was a pretty good fall for another rare dove: White-winged Doves. There were three reports, including John- sons Landing, Thunder Bay 18-30 Oct (AAE), Long Point (tip), Norfolk 22-23 Oct (RWW, JBF, EKH), and Thunder Bay, Thunder Bay 23 Oct–5 Nov (CJK, BJK). Less rare but still noteworthy, a Mourn- ing Dove at La Vallee Township 1-2 Nov (MSD) represented a record-late date for Rainy River. Notable reports of Black-billed Cuckoo included a rare James Bay record at Longridge Pt. I.B.A., Cochrane 8-12 Aug (CAF, m.ob.) and an incredibly late record at Atikokan, Rainy River 9 Oct (DHE). Now virtually gone from the province, any sighting of a Barn Owl is notable. There- fore, one at Windsor, Essex 2 Oct (PR) was noteworthy but was also overshadowed by Ontario's most northerly record, a bird photographed in the middle of nowhere, more than 100 km north of Thunder Bay at Mirage Lake, Thunder Bay 18 Oct (EML, HDL). The first Snowy Owl of the fall was found at Kitchener, Waterloo 13 Sep (MVAB, KGDB, JGB), almost certainly represent- ing a bird that summered. The Snowy Owl flight was much reduced from the previous two falls with only about 150 individuals re- ported from late October onward, compared to nearly 500 during fall 2014. There was not a detectable movement of Boreal Owls south again this year, but a Barred Owl at Kingsville, Essex 10 Nov (MD) was quite exceptional for Ontario's "deep south" and a Boreal Owl at Algonquin PP (Found L.), Nipissing 27 Oct (LAF) was one of only a handful of records for Algonquin. Northern Saw-whet Owls dipped below average again with P.E.Pt.B.O and L.P.B.O. banding 459 and 282, respectively. The first Rufous Hummingbird since fall 2013 was at Roseneath, Northumberland 30 Sep+ (CS). Red-bellied Woodpeckers continue to show up in n. Ont with five records from Thunder Bay, including birds at Thunder Bay 21 Sep (BJM), T.C.B.O. 12 Oct, Thunder Bay 13-17 Oct (BKap, SKap), One of many neotropical migrants found abnormally late into the fall, this Red-eyed Vireo was exceptional at Oakville, Regional Municipality of Halton 12-16 (here 12) November.
