I LOVED this darling picture book!  The story is about an adorable bird named Blue who woke up one morning to an “egg” landing in her nest.  The setting is Central Park, NY, with children having a snowball fight below her tree.  Blue welcomes Egg but decides they must find her mother.  They search high and low but no one claims the missing “egg”.  Blue and Egg settle into a fun life of adventure around New York City until spring comes and Egg mysteriously starts to shrink.  Blue tries everything to help, but alas one morning wakes up to Egg missing and a puddle below her nest.  She discovers in that puddle a beautiful pink flower which she promptly plants, deciding that Egg must have simply bloomed.  The illustrations are colorful cut-paper and the reader will delight in all the wonderful details.  This would be a fun read aloud for elementary.
