Professional birding amateur and national bestselling author Matt Kracht has had it with these damn birds. His new book is a warning — a field guide to help you identify and stay away from the absolute worst birds ever to plague planet Earth. Lucky for you, we’re pairing it with a Wren Compact Scope so you can spot Kracht’s 50 worst birds.

The high-quality monocular offers a 6X 18mm zoom magnification with a bright and sharp view, powered by BaK-4 prism glass. Ergonomic and grippy, the scope fits snugly in your pocket and includes a case to keep it safe and a lanyard to wear for quick bird-spotting access.
