Pittock Mansion 4-21-11


The grounds around Pittock Mansion in northwest Portland are a favorite spot for spring migrants. Most people visit this park to tour the ostentatious limestone house, but birders prefer the brushy hillsides and the woods around the parking lot.

Since we are still locked into a cold, damp weather pattern, most of the spring migrants have not yet arrived, but good numbers of winter residents were flocking and ready to move out.

Autumn migration


It has been a good migration so far in the Portland area, with nice weather and good numbers of songbirds being reported. Swainson’s Thrushes always come through our property in September to eat dogwood berries. At night, you can hear the calls of these birds as they fly overhead.

Birds are not the only autumn migrants. Lots of dragonflies are on the move, as well. I don’t know the dragonflies, so if you can ID this one, please leave a comment.

Portland’s hilltop migrant traps

In the current issue Birder’s World,  I have a site guide for Mount Tabor Park in southeast Portland. Mount Tabor is a forested hill (actually an extinct volcano) surrounded by residential neighborhoods. The elevation and vegetation attract good numbers of migrant songbirds every spring. A similar effect can be seen at Pittock Mansion in northwest Portland.

Here is the view from Pittock Mansion, with snow-covered Mount Hood in the distance. The forested hill in the center of the photo is Mt. Tabor. You can see how these islands of habitat rising above the urban sea would be attractive to migrants.
