| 1930 | Summer |  |  | Two nests of this species were reported, the first at Hyland Lake, near Minneapolis, on April 26th (the  writer). It was situated at least fifty feet from the ground  and held two well-developed young. The other nest was found  by Ernest Stein and Ralph Woolsey and was placed in a more  unusual location, on the ledge of a cliff. It contained one  YO\Ulg bird.  | 
| 1931 | Summer |  |  | Two young still in the nest on March 29th (S'"-"r..l.ey Stein) a11d another nest with two young on Nay 3rd  (Stanley Stein and R:·.lph Hoolsey).  | 
| 1932 | Summer |  |  | The earliest nest of this villainous hooter was found on Harch 25th by Stanley & EJ.onest Stein and  Leander Fischer. There were 2 smll young in it. The latest  was seen May 1at at which time the young wore.3/4ths grown  ( B reckenridge) •  | 
| 1933 | Summer |  |  |  Elovon nests of old baleful-eyed Bubo were reported. Breckenridge  found tho first in Anoka County on February 18th. The contents  wore 2· eggs. The last was f ound in Rcse(l.u County by Fryklund on  April 5th ru1d contained 3 eggs in which incubation was advanced.  Him:1enz found 2 largo young of this species in an old Heron1-s nest  in the mdst of a Great Bluo Heron colony on l-io.y 4th. The degree of  runity  -J4  experienced is left to conjecture, but as thex~e were no yotmg  herons at this date the two species probably got along fairly  well. Stein and the writer found the oustom.a:t:-y stercoraceous  pugence permeating the interiors of several hollow--tree habi taions of their acquaintance, but do not feel that it should  be classed as an inducement to find owl•s nests.  | 
| 1934 | Summer |  |  |  A number of obaeryers reported nests of this power:f:\11 terror of tho  ni@t, but our friends from St. Cloud aaain lead th | 
| 1935 | Summer |  |  |  Dobie saw a nest in the vicinity of Pnrk Rapids April 2nd.  In a nest that hadibeen used for the last several years,  BraCkett found 3 downy young one-third grown April 21st  about 2 miles west of Shakopee. The nest lay in a large  hollow snag of a huge basswood tree.  | 
| 1937 | Summer |  |  | On April 7, near Red Wing, Breckenridge saw two young cat owls that could fly; Dr. Mahle found a nest ~hat held one downy owl on April I8, near Plainview, Minn. | 
| 1938 | Summer |  |  | The earliest nest of this species was found at Minneapolis on Washington's birthday by D. Struthers, B. Upson, and W. Zimmerman; it held one egg. R. Voth found the second nest on February 28 at St. Joseph; it was complete but empty. At Bush Lake, Hennepin County, on March 24, K. Carlander located a nest with eggs. The first young were found by G. C. Kutz at Stillwater on April 3· On April 12 at Upsala, A. B. Madden found a nest with one egg; subsequently it har~.:hed. On April 14 at Minneapolis, Struthers and Upson saw 2 young Great Horned Owls.  | 
| 1940 | Summer |  |  | On February 27, a nest with 3 eggs was found at the Heron colony near St. Cloud, by the T. S. Roberts Club. A. D. DuBois found on April 22, at Minnetonka, a nest with 3 young. The 2 young St. Paul ornithologists, Harrell and Longley, found a nest with 3 young on May 4·  |

| 1945 | Winter |  |  | Present throughout the year. | 
| 1949 | Winter |  |  | Flicker, Evening Grosbeak, and Tree Sparrow.    Due to the fact that the mountain  ash trees were denuded of berries by  American Robins and other species in migration,  Grosbeaks were scarce in the area covered  by the trip. During the winter  in Duluth about seventy-five Evening  Grosbeaks came daily to a feeder.  There was an influx of Evening Grosbeaks  in southern, w e s t e r n and  central Minnesota, due partly, no doubt,  to the severity of the weather in January  but the scarcity of food in the  north was the main reason for their  :t]pearance in such unusual numbers.  In St. Paul A. C. Rosenwinkel saw  several flocks of Evening Grosbeaks,  some of them eating sunflower seeds  at feeders. One flock fed on seeds of  |

| 1963 | Fall |  |  | the Arctic subspecies was found injured by a hunter  near St. Cloud on Nov. 8 and brought  to Jane Olyphant. She nursed it back  to health and released it a short time  later, after securing some excellent  photographs. The facial discs were  snowy white and perhaps the best iden tification character was the iris color  -pale lemon-almost a whitish-yellow.  On Nov. 24 in Stevens Co., R. Grant  reported a very pale Great Horned  Owl which he thought may have been  the Arctic subspecies. Dr. Warner of  the Museum staff also received a re- port of what may have been one just  north of Pipestone, in late fall. Does  this subspecies move southward in conjunction  with the periodic Snowy Owl  invasions?  |
