Even the meal worm feeder which had been successful last spring wasn't attracting any hungry insectivores and was still completely full.
But then, a few days ago at breakfast we saw movement at the window. A magpie hovered against the window, picked up some meal worms and then darted back out of view! I never knew magpies could hover, but apparently they can. Over the last few days (while I've been away) the magpies have returned again and again, learning that the window sill can be sat upon to feed and so we don't get the entertainment of hovering anymore. Now the feeders empty and I need to fill it up again, which I've very happy to do!
Hopefully the regular visits from magpies will encourage the other local birds to check out the seed feeder, which is only a few feet away but is still as full as ever. We'll have to wait and see.
