Migratory Birds Research Station

Introduction

Many migratory birds pass through the Portland area every year. As part of the Great Northwest exhibit, we would like to place feeders throughout the exhibit to attract local birds. We hope to use the information gathered at this research station to determine what birds visit the zoo and if feeders will attract birds to visitor areas.

QUESTION

Which species of birds visit the zoo at different times of the year?

What do the graphs show?

What birds are most common on the zoo grounds in the spring?

Are the same birds here year round?

Things to think about

Where do the birds go when they are not in Oregon?

Why do some birds stay year round and others migrate?

Where might be other places in the Portland area to look for other types of birds? Where might you find ducks? Wading birds like great blue herons?
