The Sandy River Delta (Birding Oregon p. 63) lies at the western end of the Columbia River Gorge. Habitats include large areas of grassland and riparian forest.
Within the grassy areas are little islands of Himalayan Blackberry. This is an alien invasive which can overwhelm native plant communities, but Common Yellowthroats (above), Willow Flycatchers, and Lazuli Buntings (below) will take advantage of the cover and perches offered by the thorny vegetation.
The groves of cottonwoods are home to many of the common woodland species found in the Willamette Valley. Bushtits (above), Black-headed Grosbeaks, Bullock’s Orioles, Swainson’s Thrushes, Red-eyed Vireo, and Yellow-breasted Chat can all be found here.
The Sandy River Delta is also known as the 1000 Acre Dog Park. Dogs are allowed off-leash except in the parking lot and on one trail. Despite the many trash cans available, some people do not pick up after their dogs, so watch your step. Here is a photo of Nala, The Birding Dog, showing off her retriever moves.
