How do they know? I live out in the country and some of my land, which I rent out, has just been freshly cut. The grass was lifted yesterday and today crows and seagulls are feeding therein. Now the crows live on the land but the seagulls, how do they know that food is available? I am 40 miles from the coast. This is also noticeable with ploughed fields, the soil would only be turned over for maybe an hour or less and again there are the seagulls. How do they find out so fast about possible food miles from the coast?
