It’s common knowledge that you can often find warblers at this time of year by looking up into flowering oak trees, as the male flowers (catkins) attract an important source of protein for birds in the form of insects. Oaks (all parts) are host to more than 550 species of butterfly and moth larvae as well as many other invertebrates, many of which are attracted to catkins.
It turns out that birds are not the only creatures that visit oak catkins in order to secure a meal. Although we think of Gray Squirrels as consumers of nuts, seeds, fruit and fungi (and bird eggs and fledglings), their preferred food in the early spring includes the nutritious buds and catkins of oaks, elms and maples. Apparently their taste buds are not the same as humans’, as people who have consumed catkins say that their taste leaves a lot to be desired. (Photo: Gray Squirrel eating Red Oak catkins.
