Whilst checking the cricket scores on T.V., spotted a sizable number of swifts in the distance (through the window, not on T.V.) with an obviously larger bird in their midst. Rushing upstairs to grab bins and then into the garden confirmed it was a Hobby. Even at quite a distance, I thought it had something in its talons as it streaked off very quickly towards Hazel Grove. There were a lot of swifts around tonight, presumably dodging the areas of rain to the west. The hobby must have been tracking them because they were not all the local breeding birds (too many).
