Birds of a feather flock together as a survival strategy, or safety in number tactics through reducing the risk of predation. It is easier to fend off predators through flocking together of metrological specimens of identical plumage. Religious organizations such as Saint Simon's Church, Ikperejere, Saint John's Episcopal, Fayetteville, and Beth Israel Synagogue, Fayetteville, survived for centuries because of flocking together of the members. Identical plumage enhanced their common bonds. When applied to people, the above idiomatic expression means that people who are similar in ethnicity, education, career, occupation, and gender tend to spend time with each other. People of similar taste and disposition crave each other's company. That explains why people who are members of an ethnic group associate primarily with their racial group. Some evidences of this exist in big cities like Chicago, New York, Los Angeles and Miami where one will almost always find a segment of the city that has neighborhoods such as China town, Little Havana, Greek town, Little Italy, etc.
