This design, by IBO songbird bander Lucian Davis, shows the diversity of crowns in Wilson's Warblers, one of our most common species at Camas National Wildlife Refuge. Adult male birds have crowns with the most black, young females have the least, with young males and adult females falling somewhere in between. All profits from this design will go towards IBO's research on Camas NWR, which will inform habitat management practices to help Wilson's Warblers thrive on the Refuge. This year we are raising money to support an expansion of the research we've already done on the Refuge, and we will be banding at a new site on the Refuge in order to better understand how habitat changes impact migratory songbirds like the Wilson's Warbler.
