1995 Best Children's Science Books (BL) The first robins of spring carefully fill a nest with beautiful blue eggs. This delightful book clearly explains how birds develop, how the parents care for their young, and just what's happening inside that pretty blue egg.This first look at robins follows a full year of growth and change: how the birds develop inside their egg during the spring, how they mature from chicks into fledglings in the summer, how they learn to fly in the fall, and how they leave for warmer climes in winter--only to return when spring comes around again. 1995 Best Children's Science Books (BL)
