It’s a good job we’re not feeding (expensive) sunflower hearts to our garden birds. I filled up a 1.5 litre feeder this morning, and now, at 3.11pm, it’s very nearly empty! It’s a pretty impressive feat, as we don’t get many Greenfinches (which will sit at a feeder and gobble away until they’ve had their fill), with the vast majority of feeder-users being tits, which grab one seed at a time. Will we buy more feeders? Not sure - it could be a bottomless pit!
