Apologies in advance for temporarily hijacking this thread but I didn't want to start another post off plus "twitter" is poignant to my question . I am calling all bird watcher's of the ornithologist variety .
I have a border in my garden which is basically fallow soil and everyday , without fail, a small flock of sparrows sit on the soil and sort of bury down in the soil , wings flapping , and then just take off . I wondered if they were simply disturbing the ground to make any little bugs/worms come to the surface so they can feed but clearly it could be for other purposes .
It's always sparrows, seem like fledglings rather than fully grown mature birds . No other types of birds seem to do it just wondered if anyone could explain their behaviour , thank you in advance for any help.
