Ibis & the Egret

As each season unfolds its wonders, a loquacious, mercurial ibis announces to his reticent egret friend that this is his favorite season: ``With long lines of pelicans skimming the wave tops and small groups of sandpipers piping the shore, with the marsh in full green and the sun bright and warm . . . don't you think summer is your favorite time?'' But with each change of season comes a change in conviction: ``I think autumn is my favorite season. . . . With the light on the water and the marsh turning golden.'' The muted palette of Sabuda's ( Saint Valentine ; I Hear America Singing ) pastels echoes the thoughtful, quiet nature of the text. But, more importantly, they impart an extra dimension to the feathered characters of this sparely told story, adding dramatic tension. Evoking a quiet, still appreciation for nature, this book may quell the day's bustle and provide a gentle segue into sleep. Ages 4-8. (Oct.)
