An illustrated poem that lists several different types of birds and puts words together to sound like their calls, but keeps coming back to the refrain, “But have you heard the nesting bird?”  It concludes with the hatching of the baby robins.  At the back of the book, and endnote answers a series of questions as if the bird were being interviewed about its nesting habits. The illustrations are all in earth tones, which might not hold immediate appeal for young readers, but they really are quite beautiful.  A good introduction for young scientists to observe the birds in their yards, looking for words to describe what they hear.
