Tualatin River National Wildlife Refuge is still a fairly new addition to the Willamette Valley refuge complex, but it offers a nice variety of habitats very close to Portland. I don’t know if the resident Bald Eagles had a successful nesting this year, but this individual was hanging out by the nest during my recent visit.
I made a quick visit to Tualatin River NWR in the afternoon heat. One of the main trails is closed off until this young Bald Eagle decides to leave the nest. Despite the flock of European Starlings cheering him on, he didn’t show any sign of leaving.
Despite the time of day, American Bullfrogs were actively singing and defending territories. This introduced species is so common in the Willamette Valley. I would think they would be a favored prey item (Great Blue Heron, Mink, River Otter, etc.) but I seldom find any evidence of predation. Bullfrogs are unfortunately very good at preying on native frogs and turtles.
My Shorebirds of the Willamette Valley class had their first field trip on Saturday. We found nine species of shorebirds, a nice collection of the expected species. We missed the Semipalmated Sandpiper that had been reported earlier in the week. All the migrants we saw were adults. The juveniles should be arriving soon, hopefully in time for our next field trip. Since I was leading the trip, I didn’t have much opportunity to seek out photos, but here are a few back-lit images.
While the bird diversity has thinned out considerably in the past couple of weeks, I had some nice views of the summer residents at Tualatin River NWR. The resident Bald Eagles still have one youngster in the nest. He is expected to fledge any day now.
Things are hopping at Fernhill Wetlands, with rising water levels, an influx of several thousand geese and other waterfowl, and a few other goodies.
A small flock of Greater White-fronted Geese were hanging out with the Mallards in Dabblers Marsh.
The resident Bald Eagles were sitting around looking majestic. I watched one carrying a stick to add to their nest.
I saw three Common Garter Snakes on this trip, including one very young newborn about the width of a linguine. The colorful individual in this photo was about 20 inches long. Note the large laceration on his neck, presumably from a predator. Despite the severity of the wound, the snake was not bleeding and he crawled away after this photo was taken, so I am hopeful he will recover.
The weather is cooling and rain is in the forecast, as our long dry summer is finally letting go.
After the wettest March on record, April has provided a few sunny days to help awaken us from our rain-induced torpor.
Much of the loop around Fernhill Wetlands has been blocked off, supposedly to reduce disturbance to the new Bald Eagle nest.
A pair of eagles has been hanging out in this little grove of cottonwoods for years, so I would imagine they are used to birders and joggers going by, but better safe than sorry.
Sandhill Cranes, seen here with a flock of Cackling Geese, were common in the morning. But as the day progressed, many birds circled up on thermals and then headed north. By noon, most of the cranes were gone.
Most of the sparrows seen just a week earlier had moved on. Two White-throated Sparrows were a treat. Singing Orange-crowned Warblers and five species of swallows were other good signs that migration is stepping up. I’m looking forward to the next sunny day.
