Song Sparrow (Melospiza melodia) is a medium-sized New World sparrow. Among the native sparrows in North America, it is easily one of the most abundant, variable and adaptable species. A 2022 study by Duke University also found that male song sparrows memorize a 30-minute long playlist of their songs and use that information to curate both their current playlist and the following one. The findings suggest that male song sparrows deliberately shuffle and repeat their songs possibly to keep a female’s attention.



Northern Mockingbird (Mimus polyglottos) is a mockingbird commonly found in North America. This bird is mainly a permanent resident, but northern birds may move south during harsh weather. The northern mockingbird is known for its intelligence. A 2009 study showed that the bird was able to recognize individual humans, particularly noting those who had previously been intruders or threats. Also birds recognize their breeding spots and return to areas in which they had greatest success in previous years. Urban birds are more likely to demonstrate this behavior.



Pine Warbler (Setophaga pinus) is a small songbird of the New World warbler family. They forage slowly on tree trunks and branches by poking their bill into pine cones. These birds also find food by searching for it on the ground. These birds mainly eat insects, seeds and berries.

The Author, Marianne Taylor has written thirty books about birds, this one she has described clearly what motivates the birds to fom goups and seek the best place to have thei nests as a group that can reach many thousands. It actually the same as humans got together in groups and founded cities to take advantage of what produced in the area for nourishment and keep their survival. There is no place in the world where the birds are not there, unless is totally barren. As remote as you might think a place is, there are birds there. Now days, you may find birds in:
The groups of birds have grown in every place on Earth. Of course they have, according to species, different forms, shapes sizes and behavior but all are based by the same instinctive idea of forming groups. This book makes you think, and understand that there is not much difference of how humans started too.
