Baby bird

On 10th May I blipped that tits were nesting in one of the nesting boxes we have on the side of our garage. Today I found this little fella on the floor, I fear that he may have fallen out of the box :( . Initially he was reluctant to move but then flapped his wings but with little effect. He then hopped behind the water butt for safety. I left him there and hope that he is somehow reunited with his ‘family’ and that he stays out of reach of our cat!
