We have a selection of bird feeders close to our kitchen window as well as a feeder stuck on the window itself. The birds are a constant source of interest & delight, especially at this time of the year, with young families of greater spotted woodpeckers, greenfinches, goldfinches, chaffinches, blue tit, great tits, coal tits, robins and so on. We don't tolerate grey squirrels at any price - these rats with furry tails are enthusiastically discouraged - they are responsible for raiding birds' nests & eating both eggs & fledglings. I'm not sure how many people realise this. We feed the birds year round & our dear GS aged 4 knows all the different species & spends hours watching them through his binoculars. We have a bird bath too - much entertainment from that as well!
