A bird and a parent

What it is to be a bird and a parent??? Well answer to this can be best given by the group of birds that live behind my house on an empty plot. They build their nests on the ground and take almost everyone even an ant to be the abductors of their little ones. I am writing this because like everyone I am bordering on becoming complete deaf by their screeching noise. Right now they are screeching because two extremely harmless cows have come to sit there and chew their undigested food. But for these birds they are two intruders and born killers so they are trying their best to scare them but from a safe distance. Thanks to the great wings and lean body, they are able to just come near the long ears of those innocent cows and screech but unaware of the stubbornness and laziness of cows. They go on tearing their throats and tearing our ear drums. Everything seems to fall apart by their torturous screech. The only thing we can do is to wait for those cows to move from there as there is nothing that can make those furious bird parents stop. It really seems a very difficult job, not of those possessive parents flying and shrieking but of us who bears the brunt of the doings of others. this proves that the award for best parents goes to....i think we all know to whom.
