The Great Blue Heron is found throughout most of North America, as far north as Alaska and the southern Canadian provinces. Birds east of the Rocky Mountains are migratory and winter in Central America or northern South America. The Great Blue Heron uses its long legs to wade through shallow water, spearing fish or frogs with its long sharp bill, especially at dawn and dusk. It breeds in colonies close to lakes or other wetlands called heronry, which average between 5 and several hundred nests per colony. Adult herons, due to their size, have few natural predators, but can be taken by Bald Eagles, Great Horned Owls and Red-Tailed Hawks. Its call is a harsh croak.
The Great Blue Heron is a “Species of Concern” and is fully protected by federal and state laws under the Migratory Bird Act. – Petra Press
On the far northern end of Riverwest was a town named Humboldt, the namesake of the street. The town was built to equip a distillery, flour, and paper mills which used the river as its source of power by way of a dam. The dam, which was located just south of Capitol Drive was destroyed several times by high water in the 1850s and again in the 1860s, and was eventually abandoned. The factories succumbed to the elements. The distillery fell into the river in 1862 and the the paper and flour mill were destroyed by fire in 1866. If you know where to look you can still see some evidence of their existence. — Mark Towne
According to census information, in 1860, Humboldt was an unincorporated community home to workers (968 households!) in nearby flour and paper mills. Residents were primarily German immigrants. Reflecting the demographics, which consisted primarily of German immigrants, street names included “Leibnitz,” “Schiller,” and “Goethe”.
