E. Allin, dated Nov. 26, states that there were also four records from the Canadian Lake· head region by that date. He also said, "It would seem that this was the bigest flight of Hawk-Owls in recent decades. This is a happy thought as only a few years ago, it was consider- ed that the Hawk-Owl had become very scarce, and until the last two or three years, we had not had a flight and rarely saw an individual since the winter of 1938-1939.'' Avi- fauna! Club records, notes of interest in recent Flickers, and information in Birds of Minnesota (1936) would seem to indicate that this owl is, in limited numbers, a permanent resident of northern Minnesota, and can be seen every winter in small numbers. An increase in these numbers (5-10 re- ports) such as we had about three years ago, probably constitutes a min- or invasion which precedes by 1-3 years the large-scale invasion, such as we have this year. The Hawk-Owl in- vasion this winter, like the Goshawk invasion, is probably without prece- dent in Minnesota

Two in Norman (1/8–2/24 along state highway 32 south of Gary GAO et al. and 2/24 along CR 39, 4.0 miles west of Syre MEB) may have been the first in the county in >100 years. Total of 15 injured or dead fide PHS, including one taken by a Northern Goshawk and one killed by a Great Gray Owl. Noteworthy south reports through 12/22 Chippewa (near Milan, present since early November) DT fide JSc, BWF, RJS, 12/25 Wright (St. Michael) fide ML, 1/21–28 Isanti (Dalbo W.M.A.) TM, 1/28–2/1 Chisago (Nessel Twp.) DP, TAN, SPS et al. Astounding was the record-high count of 42 hawk owls on the Sax-Zim CBC 12/20 St. Louis fide MSS.
2005Spring Largest documented invasion in state history (The Loon 77:132–140). Pairs lingered into April in St. Louis (4 locations) and one at the Koochiching/Lake of the Woods county line 5/11 may have moved three miles east by early June, but none were known to nest.
2005Summer One report: 6/9 Koochiching fide JMJ.
2005Fall Major invasion echoing last year's record-high numbers (The Loon 77:132–140). Early north 10/10 Roseau JD, 10/21 St. Louis FJN. Unlike last winter, none strayed outside of the coniferous forest zone.
2005Winter Excluding eight potential breeding birds discovered in April and May 2006, PHS compiled a total of 139 individuals in 15 north counties between 10 October 2005 and mid-March 2006, 109 of which were discovered during the winter season. High count of 12 individuals 12/31 Roseau (Roseau CBC) fide BJo. At least one bird present all winter at Agassiz N.W.R. fide JMJ.
2006Spring Many early March reports from North-central and Northeast; wintering birds mostly gone by end of March. Few reports in April; numbers up in May with record-high number of breeding birds (see summer report). Probable non-breeding bird 5/8 Clearwater MHK. Injured bird 5/17 Beltrami RBJ.
2006Summer Most summer reports ever: observed in Roseau, Lake of the Woods, Koochiching, Beltrami, Itasca. New nesting record for Beltrami DPJ.
2006Fall One seen 8/10 Itasca BJS was probably related to high number of breeding birds this summer. Potential migrants 10/23, 11/8 Lake of the Woods GMM, 11/12 Aitin fide WEN.
2006Winter5 Overwintered along Rice Lake Road, Duluth beginning 12/10 m.ob. Scattered reports elsewhere in North-central and Northeast, with a high count of 2 on 2/17 Beltrami DAB, JWH.
2007Spring3 Overwintered through 4/1 St. Louis (Rice Lake Road, Duluth) fide JWL. All other reports: 3/6 Lake of the Woods KVH fide JMJ, 5/3 Lake SVK fide JWL.
2007Fall1 All reports: 11/10 St. Louis (near Cotton) BKY, 11/29 St. Louis (S.R. 61/C.R. 42) fide JWL.
2007Winter4 Down slightly from last year and concentrated in the North-central and Northeast regions. Individuals were reported 1/12–13, 2/2 and 2/7 Cass ABi, BAW, and 2/8 RBW; 2/6 Itasca SC; and 1/27 Aitkin fide JWL and east to St. Louis. Probably overwintered 12/14–2/17 St. Louis in the Sax-Zim Bog fide JWL, MHe, m.ob. Also frequently reported was an individual near the Duluth Airport 12/15–1/26 St. Louis m.ob.
2008Spring2 Three reports: 3/2 Cass DAB, JEB, JWH, 3/5 St. Louis fide JWL, 4/13 St. Louis (Sax-Zim) JMa.
2008Fall6 Observed in Beltrami, Cook, Itasca, Lake, Lake of the Woods, St. Louis beginning 10/29 Cook (2, Gunflint Trail) EEO (median 10/17).
2008Winter101 A respectable 35–40 individuals reported north in a rectangle formed by Carlton and Lake in the Northeast and Roseau and Clearwater in the Northwest. Eleven individuals tallied statewide on CBCs. Totals were up somewhat from previous two years, but paltry compared to the mega-invasion of 2004–2005 when 154 were estimated in December alone including a North American CBC record of 42 on the Sax-Zim count (see The Loon 77:132–140). Unexpected was a brief visit by a single bird that pushed south into Nicollet where it was initially found by a non-birder and was well-documented ph. ChH, ph. RMD.
2009Spring7 Reported in Beltrami, Cass, Koochiching, Lake, Lake of the Woods, Roseau, St. Louis as late as 4/25 Lake of the Woods TDi. High count 4/21 Lake of the Woods (6) TDi.
2009Fall6 Early north (median 10/22) 10/31 St. Louis ABL. Observed throughout the remainder of the season in Aitkin, Beltrami, Cook, Koochiching , Lake, St. Louis. Approx. 27 individuals reported.
2009Winter14 Seeing what was becoming an invasion year, MLH compiled records of 96 individuals in 14 north counties between 10/22/2009 and 3/17/2010. A review of all electronic records submitted for the winter period revealed approximately the following number of owls: 33 in December, 40 in January, and 34 in February for a total 1/7. No doubt this total includes some birds counted more than once; nonetheless, the actual total represents about the 5th highest invasion for the state (see Svingen and Nicoletti, The Loon 77:3). Most unusual were reports 1/20 and 1/31 Norman (East of Ada at intersection of CR24/CR27) fide JMJ. Recorded on 10 CBCs statewide.
