Past Video Presentations

The ASC Board has decided to provide a link to presentations for 2021-2022 from one or two previous months but not to continue linking to all the presentations for the past year. Former ASC Vice President Mark Baldwin has recordings of the 2020/2021 speakers, but we are unable to archive them on our website. Contact for more information.

Wary by nature, yet brave under fire, the magnificent bird has long thrilled the sportsman. Some attribute the bird’s decline to habitat loss, but Worth Mathewson, author of a complete natural history of the species, carefully builds his case to the contrary. Zoom link

A key challenge facing the wind industry is the potential for turbines to impact wild animals, both directly, via collisions, and indirectly due to noise pollution, habitat loss, and reduced survival or reproduction. Research Statistician Manuela Huso presented what she has learned from collaborative work and how the wind industry can lessen the impacts. Zoom link

Kelly Hazen shared information about the natural history of Greater Sage-Grouse and Oregon’s Adopt-A-Lek program. Greater Sage-grouse (GSG) are chicken-sized  birds that are found in 13 western U.S. states and three Canadian provinces. Habitat fragmentation and development have caused severe declines for this dramatic bird.  Link to Zoom recording

Jonathon Valente discussed the OSU College of Forestry Oregon Marbled Murrelet Project ( TLaunched in 2015, the focus of the project is to understand basic murrelet biology. Jonathon discussed how the research team is using cutting-edge technology to better understand murrelet habitat requirements, movement, and limitations to population growth, as well as how this research will be used to improve management of public and private forest lands.

Marbled Murrelet
These small seabirds spend most of the year at sea fishing, but they fly inland to nest in in the forest. Because they rely on old-growth trees for nesting, logging is a threat to their numbers. They are listed as Threatened in Washington, Oregon, and California.

ASC members Matt Lee and Sue Powell shared their photos and stories from their “bucket-list” trip to the Ecuador mainland and Galapagos Islands in October 2021. Ecuador is small but has mega-diverse habitats, including coastal lowlands, foothills, Andean peaks, dry forests, cloud forests, high-altitude Páramo grasslands, Amazonian jungles, and Pacific Islands. This habitat diversity supports 1700 species of birds, more than 130 of which are hummingbirds.

blue-footed booby
About half of all breeding pairs of Blue-footed Boobies nest on the Galápagos Islands. Male blue-footed boobies show off their bright feet during courtship. These fish eaters dive for fish and sometimes swim under water in pursuit of their prey.

March 2022

OSU researcher Matt Betts presented recent findings on (1) the importance of old growth for moderating the effect of climate change on birds, (2) the effects of deforestation on species endangerment worldwide, and (3) the effects of herbicide on birds and biodiversity generally in the Oregon Coast Range.

Dave Mellinger spoke about developing user-friendly acoustic tools for studying marine mammals and their environment. Results are important for research and  conservation of marine species throughout the world. Dave ‘flew’ ocean gliders underwater to study sperm whales in the Gulf of Mexico.

Ryan Baumbusch is researching the foraging ecology of Barred Owls in the Pacific Northwest. By examining the stomach contents of owls removed from Spotted Owl territories, he is inventorying what they eat and comparing it to Spotted Owl diets.

Northern Spotted Owls (NSO) are native to the west coast. Recently Barred Owls have expanded their territories into NSO nesting areas with alarming
