Yes, even today, in the midst of a covid-19 leading the world into mayhem for a while, even today the crows are cawing. I heard an amazing song bird this morning. He had only one song it sounded like, with only two notes. But he sang it so well that every other bird with a (some may say, more complex birdsong) joined in with him or her: the overal effect was magnificient. He had just two notes to his song he kept repeating over and over again. yet in fact, when one listened closely, he was kind of the lead in the trees for all the bird songs this morning.
