Perhaps 15,000 crows roost during the winter months in a small patch of wetlands in Bothell, Washington. Even more amazing: each night, the birds arrive together.

Nature photographer Kevin Ebi spent several months documenting this spectacle, presenting his strongest images and a personal essay in the electronic book, In For The Night.

Kevin’s images have been used by National Geographic, Smithsonian, National Wildlife and Lonely Planet. His image of a rainbow in Haleakala National Park was featured on a Forever U.S. postage stamp to commemorate the National Park Service Centennial.

The eBook is available as a high-resolution 70-page PDF, compatible with iPads and other devices that can use the Adobe Reader format.
