See-sil




Fifteen explorers met at the end of Royal Avenue May 14th to explore the BLM's See-sil area. Before we even left the parking lot we were treated to the appearance of an American Bittern, a shy bird more often heard than seen. The tall, yellow-legged bird went into its "oh, I'm just some grass" appearance, stretching its head high and pointing its beak upward, but soon walked cautiously along the edge of the road next to a swampy area, then disappeared over the bank. The arrival of a car startled it and the bird flew. Also at the parking lot was a flock of bright yellow goldfinches, one minute posing on the fence, the next busily gathering seeds in the tall grasses.

We walked down the road a short distance and then out into the fields where the City of Eugene's Restoration Ecologist, Emily Steel, pointed out a variety of plants native to the area including popcorn flowers, buttercups, disappointing buttercups (very tiny flowers on a big plant), and camas, which was nearly past. This was a great opportunity to view and compare the Oregon White Oak and some nearby black oaks. We were awestruck by one particularly large white oak with massive lower branches.

We also viewed an area where the oaks were actually growing too densely so some have been removed in a habitat restoration effort in order to allow the others to grow.

Birds seen on the trip included the bittern, goldfinches, red-tailed hawk, Savannah sparrow, tree swallows (there are bird houses for them in one area), and a meadowlark. There were the classic signs of acorn woodpeckers (a large dead branch with holes in it and an occasional acorn still plugged into the holes) but we didn't see any of the birds. Near a row of blackberries and other shrubs at least three rabbits (who knows with rabbits!) ran quickly from grass to shrubs. When we arrived back at the parking area, we could see two white pelicans soaring in tight circles high above us.

Edison Elementary Field Trip May 2

Last Friday, an Edison Elementary 3rd grade class enjoyed a surprisingly sunny field trip to the West Eugene Wetlands. It was a great second day of American Wetlands Month 2008 for netting and getting a close look at vernal pool inhabitants and a walk along Tsanchiifin Trail. A few WREN board members also participated in the field trip! Thank you to Susanne Twight-Alexander, board member, for a few fun photos...

Water Scorpion, A Cool Wetland Bug!!


Water Scorpions are insects in the Order Hemiptera (the true bugs), Family Nepidae, and the genus is Ranatra. Note the front legs which are modified for grasping prey. They inject their prey (including insects, small fish, and tadpoles) with saliva which digests tissue after which the mixture is sucked out. You can see the beak between the front legs. The long tube on the rear of the abdomen is used for breathing from the water surface so they tend to stay in shallow water or near the surface. Although they can't be seen, a pair of wings is hidden beneath the leathery outer wings, and they can fly. Water Scorpions overwinter as adults. This one was found at Sandpiper Pond on April 26.

Wetland Wander

-by Susanne Twight-Alexander, WREN Board Member


This morning's (last Wednesday's) wetland wander started with overcast skies but we were fortunate the showers held off until we were nearly to our cars. The Nature Conservancy's Matt Benotsch led our group of eight from the 18th street across through TNC fields on a "burn" road. We were able to see the difference between areas where trees and undergrowth are rampant, inhibiting the growth of native plants and those where burning and/or plowing are encouraging their growth. Right away there were bird observations of acorn woodpeckers and singing meadowlarks. Other birds spotted during the trip included juncos, songsparrows, robins (of course), and Canada geese. Matt pointed out many of the early spring plants, a few of which were flowering. A new one to me was the bittercress, delicate white flowers on small plants that love to have their feet in the water. We also found a buttercup and some saxifrage in bloom. Matt showed the group the leaves of the Kincaid Lupine (the favorite food of the Fender's Blue Butterfly) just beginning to emerge and we were fortunate to find a Bradshaw's Lomatium at the edge of an area which is being protected to encourage their development. (that was the flower in last weeks post!)
