| 1931 | Summer | Adults building a nest June 10th (Swedenborg). One younc nearly full grow.a in tamarack swanp north of St. Paul, July 3rd (several observers) | ||
| 1932 | Summer | A nwlber of heronries of this species were found, but the contents of the nests were determined only when the young birds were in the nest, first on June 12 at Lrute Minnetonka (Ralph Eisele & Walter Dewey), and last on July 12th at Rainy Lake1 the young being nearly full-grown in the latter colony (Swanson).. | ||
| 1933 | Summer | A colony of about 55 pairs of this bird,.,as visited by Hiemenz on May 4th. He found them "nesting in tall Basswood and Tamarack trees along the Sauk River about 2 miles west of Rockville, Stearns County. l climbed one tree tvhich gave me the view of 1 0 nests. Five nests held 5 eggs eacb and 5 nosts held 4 eggs each. The birds were incubating on most of the 11ests. The eggs seemed fresh. Several nests were just being built. One tree held 10 nests and 2 held 7 nests. | ||
| 1934 | Summer | Four colonies were reported. The first, visited by Hanson and Hiomcnz, was located along the So.uk.tliver, 2, miles west of Rockville, Stenrns County.

On April 22nd one nest hold 3 eggs and birds wore on ·nost cf the other nests; however, these observers report, "This colony seemed much smaller th~·it was last year, probably only about 40 pairs nesting." Another colony was visited by Hier.:enz, who writes, "On April 9th, the birds were bui).ding and the nests soened tiliaost ccnplete. They were all new structures, ns the fo.ruor living nearby said that all tho old trees with nests had boon felled during tho w:i.nter, having been dead. Thoro we~e possibly 75 pairs nesting." The third colony, located near Barnesville, Ottertail Count:{, \·!as visited on May 17th, and consisted of about 80 nests, r.1ost of which were probnbly or1pty. or about 10 nests investigated, one or two had 2 or 3 eggs, according to Woolsey, who visited tho colony. The latest rccke~r reported was seen by Mnrius Morse and his friend Feeney, on Au~st 1st at Itasca Pnrk. The nests, nunbering "probably over 10011, were perched in the tops of sene 80-foot Norway Pines. At this tir.1e all but 2 or 3 uere vncant. Nearly full-grown young were seen in two of the nests. | ||

The lake in this case happened to be Frog Lake, in Western Minnesota, where this spooky Great Blue Heron eats bullheads all summer long. His rapier thrusts, with his razor sharp bill are so accurate he seldom goes hungry. Ernest Strubbe, Alberta, Minnesota has observed many Blue Herons on Frog Lake and he states that "on many occasions the heron beats the fish on the ground until it is tenderized to suit his pallet."
