Low Head Dams Are Dangerous
The reds of the maple highlight the danger that low head dams pose to kayakers and wildlife. This dam probably exists to provide water to canal, or maybe it's historical. I don't know, but looking from upstream, you would never realize there is a dam there except for some warning sides. That said, the Mohawk is a mix of rapids and falls around Peebles Island.

How Where You’re Born Influences the Person You Become
As early as the fifth century, the Greek historian Thucydides contrasted the self-control and stoicism of Spartans with the more indulgent and free-thinking citizens of Athens.
Today, unique behaviors and characteristics seem ingrained in certain cultures.
Italians wildly gesticulate when they talk. Dutch children are notably easygoing and less fussy. Russians rarely smile in public.
As developmental psychologists, we’re fascinated by these differences, how they take shape and how they get passed along from one generation to the next.

Will insecticides targeting EAB harm woodpeckers?
Will insecticides targeting EAB harm woodpeckers?
This is unlikely. Woodpeckers feed on live, mature EAB larvae, mostly in late fall, winter and early spring. Many of these mature larvae overwinter in the nonliving, outer bark where they will not be exposed to systemic insecticides. Imidacloprid, dinotefuran, and emamectin benzoate are much more toxic to insects than to birds that have been tested, and insecticide concentrations that have been measured in treated trees are far below the levels known to be toxic to birds. An EAB larva that has been killed by insecticide will desiccate quickly and decompose. There is little evidence that woodpeckers will feed on larval cadavers. Furthermore, living larvae that are suitable prey for woodpeckers will not have been exposed to a lethal dose of insecticide, and these products do not bio-accumulate in animals in the way that fat-soluble insecticides such as DDT do. In Michigan and Ohio, where EAB has been established for several years, many ash trees have been treated with systemic insecticides. There have been no reported cases of woodpecker poisoning caused by insecticides applied for control of EAB.
