While growing up at the place where I now live, the only black bird that I know of are Crows. I get to see these Crows almost everyday when they fly, as they still do now, from South to North in the mornings and in the reverse direction come evenings, squawking as they fly slowly up high overhead.
These days, there is another rather big black bird, a migrant bird in fact, that comes visiting only in the month of December - 10th December to be exact for this year. They are the Asian Koel. I think they are quite common in the coastal areas. But up to about 30 or even 20 years ago, I don't think I have ever heard or even seen one before. I wonder why and when did they decided to move inland?
