Tualatin River NWR

eagle nestI 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.

gadwallI saw several pairs of Gadwall, but no ducklings yet. This male was putting on a show for his lady friend.

spotted sandpipersI often find Spotted Sandpipers perched on man-made structures.

bullfrog 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.

Sandy River Delta

chat singingI took Nala to the Sandy River Delta this week. One of the target birds for this area is Yellow-breasted Chat, a species hard to find elsewhere in the Portland area.
chat turnedThis was the only individual I found that day, but new migrants are arriving daily. Willow Flycatchers and Eastern Kingbirds, two other specialties of this site, were largely absent during my visit, but were reported a few days later.

pileatedWe often associate Pileated Woodpeckers with dense forest, but this species is often found on isolated cottonwood trees along the Columbia River.

Fort Stevens State Park

When the tides are right, the area around Parking Lot D at Fort Stevens State Park can be very productive.

caspian ternsOn my recent visit, I found about 400 Caspian Terns in the bay. Many of the birds were presenting fish to their lady loves, and a few were rewarded accordingly (nudge, nudge, wink, wink). A Bald Eagle would occasionally take a pass at the flock, sending the terns off in a big swirling mass, but the birds would quickly settle down again.

bonaparte's gullOne of my favorite birds of the day was this breeding plumaged Bonaparte’s Gull. I watched the bird fly in and settle on the mud flat. I snapped a couple of frames from a great distance, planning on getting better views. But, as is often the case, the bird took off before I could get any closer.

shorebird flockOver the past few years, this site has been become a productive spot for shorebirds. The spring shorebirds migration is well past its peak, but there were still a few birds around. This little flock was actively feeding along the shore, so I sat on my knees in the sand and waited for the birds to come to me. Shorebirds are very wary of people standing upright, but if you sit down, or better yet, lie down, the birds will come quite close.

dunlinThis blurry Dunlin was the only member of her species in the flock.

Spring Shorebirds

I had hoped to get to the coast this week, but a big weather system was blowing in so I  visited Fernhill Wetlands and Jackson Bottom. Both sites had a few shorebirds sporting their breeding plumage.

long-billed dowitchersLong-billed Dowitchers at Jackson Bottom. The sticks in the foreground are willow stakes planted by Clean Water Services. As these willows grow, they form a canopy over the mud flats, making the habitat useless to migrating shorebirds. Birders have been complaining about the practice at this site for years, to no avail.

Silver Lining

I led the field trip for my Warblers and Flycatchers class Saturday morning. We walked around Mt. Tabor Park in SE Portland for several hours. Spring migration tends to occur in waves, with some days producing large numbers of migrants, and other days producing very few. Unfortunately for the class, Saturday was one of the “very few” days. But despite the total lack of flycatchers and the near absence of warblers, we still enjoyed whatever birds we came across.

sapsucker on post 2One of the more entertaining birds of the day was this Red-breasted Sapsucker. This individual has become rather famous for drumming on the metal band on the concrete street light.

IMG_4556In the woods nearby, we found this sapsucker excavating a new cavity.
IMG_4554So even though we dipped on most of our target species, we proved again that there is always something to see.

Any Minute Now

yellow-rumpedSpring migration is picking up, with good numbers of warblers just starting to arrive, just in time for my Warblers and Flycatchers class next week. Here is a Yellow-rumped Warbler in a field of little flowers which I think are spring beauties. How appropriate is that?

kingfisher burrowNot a warbler, but still a neat find is this Belted Kingfisher burrow along the Columbia River. The burrow is pretty low, and in a area that gets a lot of human and dog traffic, so it will be interesting to see if the birds can successfully nest here.

Fernhill Wetlands 10 April 2014

I took a quick tour of Fernhill Wetlands this week. Great changes are planned for this site. The main lake will be made smaller, and the other two impoundments will be replaced with emergent wetlands. I am looking forward seeing how things progress. Here are some birds and other critters from the trip.

muskrat climbingI don’t think I’ve ever seen a Muskrat climbing a tree before. This one was gnawing off a branch to get to the leaves.

tree swallowTree Swallows are swarming around Fernhill Wetlands, no doubt encouraged by the many nesting boxes that have been installed at the site.

northern shovelersNorthern Shovelers were the most common duck species on the lake.

carpSeveral schools of Common Carp were active at the surface. I don’t know if they were feeding on aquatic insects or involved in spawning.
