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.

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.

yellow-rumped warblerMany Yellow-rumped Warblers were passing through, mostly the Myrtle race, with only one Audubon’s.

cackling geeseFlocks of Taverner’s Cackling Geese were feeding in the fields north of the main lake.

garter snakebaby Garter Snake. I’m not sure if this is a Common or Northwestern Garter.

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.

red-winged blackbirdA few Red-winged Blackbirds were displaying. There aren’t very many Red-wings at Fernhill since most of the cattails died off several years ago.

The end of March and beginning of April have been cool and wet. Spring is progressing, but seemingly very slowly. Here are a few images from the past week.

pacific wren frontPacific Wrens are singing everywhere. This bird was at Powell Butte Nature Park in SE Portland.

nala frontNala is far more interested in fetching sticks from the river than looking at birds. This “stick” in the Columbia is probably her biggest to date.

wf geese duoThe morning at Smith and Bybee Wetlands in northwest Portland started out foggy. At the Smith Lake canoe launch, 12 Greater White-fronted Geese were among the many waterfowl. It is getting late for White-fronts in the Willamette Valley.

waxwing 1There were a lot of Cedar Waxwings flycatching and feeding on various fruiting trees. This is a young bird, given the overall scruffy appearance and the lack of red tips on the tertials.

pileatedThis Pileated Woodpecker was very vocal and perched out in the open on a distant utility pole.

rs hawkThis Red-shouldered Hawk was among the many Red-tailed Hawks and Northern Harriers present on the property.

marsh wren front 1The current low water levels allow you to hike quite a ways out into the wetlands. Marsh Wrens are common in the shrubs and reed canary grass.

song sparrowSong Sparrows are also common in the tall grasses. The best bird of the day was a Swamp Sparrow, but he eluded the camera.

frog 3Pacific Chorus Frogs were singing everywhere, but this is the only individual I could see.

I made a very brief stop at Delta Ponds in Eugene. Since the site is right by a major highway, the traffic noise effectively eliminates any birding by ear. But the ponds attract good numbers of waterfowl and herons. A Black Phoebe was a nice find.

egretGreat Egrets and Great Blue Herons were common. I am incapable of photographing white birds on a sunny day without them totally washing out.

beaver dam low resBeaver dam. We didn’t see any Beaver, but we did find two River Otters.

pond turtlesThe best sighting of the day, despite the slight social awkwardness, was this pair of Western Pond Turtles, a lifer for me. Western Pond Turtles, one of only two native turtle species in Oregon, are nearly extirpated from their range north of Eugene, and are listed as critical on the the Oregon list of sensitive species.

cimarron riverI spent the day on the Cimarron National Grassland in southwestern Kansas. It is a frequent destination for Kansas birders lured by the possibility of southwestern species that only make it into Kansas here. The area has seen a lot of changes in recent years. A large fire swept through the area a few years ago, killing many of the cottonwoods in the riparian corridor. The last two years have seen severe drought, followed by four inches of rain in the past several weeks. I have been visiting this area since 1984, and this is the first time I have ever seen water flowing in the Cimarron River.

Even during the slow birding season of late August, you can count on finding Western Kingbirds in trees and on power lines.

point of rocksThis is Point of Rocks, one of the few actual landmarks in this area.

point of rocks 2This is the view from the top of Point of Rocks, with the Cimarron River corridor on the left. They say you can see wagon wheel ruts from the Sante Fe Trail from here, but I’m not sure which tracks were made by wagons and which were made by pickup trucks. Birding is usually slow here, but sometimes the brushy slopes attract interesting migrants, and raptors often fly by at eye level.

rock wrenNo matter how slow the birding, you can always find a Rock Wren or two at Point of Rocks.

sand bluffWhile it may look like rock, this bluff above the Cimarron River is made of sand.

bullfrogDespite the dry climate, there are a few ponds on the grasslands. This American Bullfrog looked especially alert.

juvenile spotted walkingThere are lots of youngsters in the wetlands these days. We haven’t had any rain in July, so water levels are dropping, concentrating wetland animals into smaller areas. This is a Spotted Sandpiper in that awkward adolescent stage.
