|-- All three squirrels discussed here forage on the ground for nuts, flowers and buds.|
|-- S. carolinensis and S. niger forage for short periods of time twice a day. Peak hours are two hours after sunrise and two to five hours after sunset.(Halloran 1999)|
|-- G. volans are active throughout the night and in addition to nuts, flowers and buds eat insects.|
|-- Acorn tannins may affect food preferences through effects on palatability and digestibility.|
|-- Captive S. carolinensis when fed a 100% red oak acorn diet lowered individual dry matter intake.|
|-- Other control individuals fed 100% white oak acorn diets showed lower protein digestibilities but did not show the negative effects of reduced eating.|
|-- The study suggests that a variety of other foods may be needed to dillute the high levels of tannic acid in a red oak diet and also to give additional nutrients. (Chung, Hagerman, Kirkpatrtick 1997)|
