Cobnut season
Throughout September and October there will be a plentiful supply of fresh cobnuts available, grown as an agricultural crop, mainly in the south of England. Cobnuts, sometimes known as filberts, are a cultivated variety of the wild hazelnut tree. So, if you have the time and inclination an hour or so could perhaps be well spent foraging in the countryside for a basketful of these highly-nutritious nuts, which will enhance the diet of any parrot, and benefit us humans too!
