The Caspian is the world’s largest tern. Though named for the Caspian Sea, where early ornithologists first observed it, this fish-hunter with a massive red bill ranges across five continents. In North America, Caspians largely nest on inland lakes and rivers; the world’s largest known colony, with more than 6,000 breeding pairs each year, occupies a small, artificial island in the Columbia River between Oregon and Washington.  Bird Collective donates a portion of its profits to bird conservation groups that work to protect birds like the Caspian Tern and their habitats.  All embroidered bird patches have an iron-on backing, but the adhesive is temporary. For durability, we recommend sewing or using a permanent, flexible fabric glue. Dimensions: 2.25" wide x 1.9" tall.
