Sunday treat for the birds

I have a new feeder which I have enclosed in a wire cage to keep the Starlings out and give the small birds a chance. Well, it nearly works - the adult Starlings can't get in but some of the smaller fledglings can (so far -but they will grow too big soon).
Since putting it up I have had at least one of each of the following -  Sparrow, Blue Tit, Great Tit, Robin and - best of all - a Wren! 
Today I gave them a little treat - as well as the seed, sunflower hearts and a suet ball, I added a few mealworms and cut up grapes. Strangely the red grapes went before the green ones.
