A tiny, seldom-seen bird has been discovered alive and well in an unexpected place. OREGON FIELD GUIDE joins a biologist who spent more than 300 days tracking and studying the elusive pygmy owl. Tune in Thursday, June 10 at 8:30pm to the stations of Oregon Public Broadcasting to find out where these remarkable birds are thriving.

Pygmy Owls – Very little is known about the tiny northern pygmy owl. It dwells in the thick forest, is about six inches tall and weighs only two ounces. With its bark-colored feathers, these birds are hard to spot. Meet a researcher who has spent three years in the woods studying the owls, mimicking their calls to locate their nests in the cavities of trees. He’s recorded some remarkable, rarely seen moments and dispelled some myths about where they’re found.

Ocean Acid - For over 25 years, a husband/wife biologist team has come to Tatoosh Island off the Olympic Peninsula to study the wildlife there. They’ve discovered that not only is the wildlife changing, but also the chemistry of the ocean is changing – fast. And scientists from around the world are seeing the same thing. Increasing Co2 emissions aren’t just affecting the atmosphere; they’re also turning the ocean more acidic. Ocean acidification could have consequences for all ocean life, but it’s the shellfish that seem to be getting hit the hardest. FIELD GUIDE checks in on the latest findings and what it may mean for the future of ocean life.

Green Roofs - Portland hopes to capture some of the 10 billion gallons of rain that flows off 12,000 acres of roofs in the city by promoting eco-roofs. The city and Oregon State University find roofs covered in plants and soil soak up and hold 40 to 55 percent of the rain that would normally run down storm drains.

FIELD GUIDE repeats Sundays at 1:30am and 6:30pm. Full episodes of FIELD GUIDE are available at watch.opb.org. Videos of the stories featured on FIELD GUIDE are available at opb.org/programs/ofg/
