Sparrows lunching

Spent most of morning cutting grass  -  you've no idea how it has grown since I last cut it before it started raining five days ago!  First really dry day and even some blue sky behind the clouds.  Lots of sparrows around as you can see from my blip:)  An unexpected thing has now happened  - when I went back to Desktop I found this blip taking up the whole screen and I can't find how to change it back to the normal Windows 10 Desktop. I must have pressed the wrong button somehow:(  Thank Goodness it's a picture I like. Hope you are all having a good weekend.
