"Discover the magic--and the science--behind the migration of warblers with this stunning photographic picture book from the award-winning author and photographer of Raindrops Roll, Best in Snow, and Full of Fall. The migrating warblers have arrived, to feed and preen, to refuel and rest before continuing on their amazing journey of thousands of miles. This photographic picture book captures in lush detail the story of these tiny, colorful, and diverse birds. April Pulley Sayre's vibrant photography has been called "striking" and "wonderful in every way" by Kirkus Reviews, and Warbler Wave is just that"-- "A photographic exploration of warbler behavior and migration"--
