I will say that is nature in all it's glory
However, we have populations propably the same size only they are of two kinds and equally destructive. One is the black bird and the other is crows
The crows over nite in a small city of 25,000 plus. They leave every morning to feed in the country side, not doing a lot of damage, spread out as they are. At nite when they return the sky turns black. The problem is they roost in the city for some unknown reason and poop all over. They make an unholy mess the numbers are so many.
The other problem is the black bird. As you may know I have mentioned at times we grow sweet corn. Black birds love sweet corn and attack just before it is fit to eat. We spend 1000,s of dollars on bird control and then feel lucky if we keep it down to a dull roar.
Left unchecked they will destroy many, many 1000's of dollars of crop and even find their way into conventional corn, but for some reason they don't seem to like the taste of conventional corn as much.
Sometimes the sweet corn is not worth harvesting if the bird control fails. If only they would stay out of our sweet corn I would love then to the death, but our daily bread comes from that sweet corn.. Have you ever seen crows walk down a corn row and pick the seed out of the ground??
So: one persons view point on 1000's of birds and the damage they can do. Plus the deer, coons, coyotes possums, skunks and assorted other wildlife. I suppose they were here 1st.
Schools of fish, flocks of birds, follow the leader
in wild random swirls ... but much, much neater
Than flight from a shark or an eagle or a hawk
That pursues their prey in a well rehearsed stalk.
nice one, John.
