Wildlife Week – Day 5: Tualatin River National Wildlife Refuge and Jackson Bottom Wetlands 05/01/2025

A day after my long hike at William L. Finley National Wildlife Refuge (post) I dialed it back a little. For day 5 of my “Wildlife Week” vacation I had two short hikes planned to revisit a pair of wildlife areas along the Tualatin River the Tualatin River National Wildlife Refuge and Jackson Bottom Wetlands Preserve.

First up was the Tualatin River NWR. We’d visited this refuge twice previously, first in March 2019 and then again in May 2023. The seasonal trails at this refuge are closed from October 1st through April 30th so today was the first day the Wetlands Loop would be open this year.

I parked at the Roy Rogers Road Trailhead as we had done in 2023 primarily because it was a little closer to Jackson Bottom.

My route utilized portions of the seasonal Wetland Trail and the River Trail to make a loop with a short out-and-back on the Ridgetop Trail. It came to 4.7-miles with about 100′ of elevation gain, most of which was on the Ridgetop Trail.

DSCN6093I believe this is a savannah sparrow.

IMG_9767It was just under 40 degrees Fahrenheit when I started, but the forecast called for temperatures to reach 80 by the afternoon.

DSCN6117Not sure what type of fish this is but they were thrashing about near the shoreline, and I had seen similar behavior the day before in McFadden Marsh at Finley NWR.

I stopped at the Refuge Headquarters to use the facilities, and this pair of bald eagles arrived at the same time.

IMG_9793I spotted an American kestrel in this snag. I had been hoping to see one during this week’s hikes.

Not a huge amount of wildlife here today but the kestrel was a nice addition to the list of species seen this week. This was by far the busiest hike of the week, possibly due to it being the first day of the seasonal trails being open. I was done with the hike at 8am so not only was it busy, they were early birds.

It was a 20-minute drive from the refuge to Jackson Bottom Wetland so it was still fairly early when I arrived at the trailhead.

Our previous visit here was last April (post) and we hiked the majority of trails here during that visit, so this was a near repeat except I went in the opposite direction (clockwise).

In addition to wildlife the preserve has some nice flower gardens near the visitor center.

Jackson Bottom was noticeably less busy than the refuge had been. It was a nice hike with a fairly steady supply of wildlife. These are both good destinations and were a nice addition to wildlife week. Happy Trails!
