How can you explain that all Black birds are Black birds, but not all Black birds are Black birds?

Answer 1

There are a group of birds classified as blackbirds. In the US there are a number of birds with the name blackbird: Red-winged Blackbirds, the most common, Tricolored Blackbirds, found only in California, and Yellow-headed Blackbirds. These birds are ictarids, the scientific name for their family. There are other birds that are black, like Crows, European Starlings, Brown-headed Cowbirds. They are not in the same family.

To confuse things even further, in Europe the bird called the Blackbird is a thrush, related to our American Robin.

Answer 2

By telling them that is what they are called. Also explaining that some black birds have absolutely beautiful colorful wings but still are blackbirds. I had a pair of them this Spring that had red and yellow on their wings. Awesome. They would whistle when they needed food. Little stinkers, but I liked them.

Answer 3

okay, how about All birds that are Black in colour do not fall into the category of being labelled as "Black birds" Other notable birds that are black in colour are Crows, Ravens, wild turkeys etc.

Answer 4

All black birds are black birds, but the bigger ones are Crows.

Answer 5

What the first one said.

Answer 6

The same way you explain that all apples are fruits, but not all fruits are apples :)
