I've been feeding a burgeoning population of greenfinches, goldfinches, blue and great tits, blackbirds, robins and the occasional starling over the winter. The greenfinches started off as a handful last autumn, but swelled to over a dozen by the bank holiday last week. I've gone through 50Kg+ of sunflower hearts and they were going through about 1Kg a day.
Anyway, last week I disappeared off to Edinburgh for a few days. I tried to fill the feeders as fully as I could on the Tuesday morning, but by the time I returned on Friday everything was empty and even the ground underneath the feeders, normally covered in dropped seed, was plucked bare. I filled up the feeders pronto, but since then the greenfinches seem to have done a bunk. I'm now down to about a third of the number of visitors and seed consumed. I'm quite sad, as the greenfinches were a feisty bunch. Do you think they have departed for pastures warmer now the spring is here?
