Forest Birds Workshop

Saturday, September 15
9am-12pm
$15/HAF member, $20/non-member

Mature Pacific Northwest forests host birds that are uniquely adapted to live in different layers of the forest. This workshop will teach you which birds to expect in our coniferous, deciduous, and mixed forests, how to detect them by sight and sound, and which adaptations help them survive and thrive.

In this class, experienced birder Laura Whittemore will introduce you to the common birds of Pacific Northwest mature forests, such as kinglets, creepers, nuthatches, woodpeckers, and owls. Learn how to find and recognize these sometimes elusive species using location, behavior, plumage, and sound. We'll start with an indoor presentation, then you'll use your new awareness on a walk through the Arboretum to detect birds by moving slowly, listening carefully, and paying attention to habitat.

About the instructor: Longtime birder and teacher Laura Whittemore loves to show beginners the tricks of the trade. She regularly teaches classes for Audubon Society of Portland and previously worked for Backyard Bird Shop, where she helped bird-feeding enthusiasts ID those confusing little brown birds. Laura holds a BA in Biology from Lewis and Clark College and has traveled in the US, Australia, South Africa, and Antarctica in search of birds.

This class is now full. Please email info@hoytarboretum.org to be added to the wait list.

Broadleaf Evergreens Workshop

Saturday, October 13
9am-12pm
$15/HAF member, $20/non-member

It's very common for people to use the term ‘evergreen’ to refer to only conifers, but this distinction isn't exactly accurate. Many genera of broadleaves, too, have a species that have opted to retain their leaves year-round. Oaks, madrones, magnolias, hollies, and others all have examples of evergreen species. In this course, we're going to focus on identification of some of these broadleaf evergreen species, and discuss how this evolutionary strategy works and why these trees are becoming more and more important in the face of climate change and urbanization.

About the instructor: Casey Clapp is an avid plant enthusiast and Certified Arborist who specializes in tree identification, risk and health assessment, and diagnostics. Currently, Casey works for the City of Portland as a Tree Inspector and previously has worked as a consulting arborist across the region. He holds a Bachelor of Science in Forest Management and a Master of Science in Environmental Conservation.
