Fernhill Dog Days

In preparation for my shorebirds class for Portland Audubon, I have made several trips to Fernhill Wetlands (Birding Oregon p. 61) in recent weeks. As expected in the Willamette Valley in late summer, species diversity is fairly low, but there is always something to see.


Green Herons are common at this site, flushing from the shores of the main lake or hunting in Dabblers Marsh.


High water levels this year have left little mud for the shorebirds. This Killdeer has found some higher ground.


Greater Yellowlegs


The shorebird class found at least six Stilt Sandpipers on their field trip. This species is a rare migrant in Oregon. I had only seen one individual in Oregon prior to this trip, also at Fernhill.

Late summer is the ugly duck season, with most birds in their summer alternate, or “eclipse” plumage. I think I know what this little duck is, but I would be interested in your opinions. Leave a comment.


This is a school of young bullheads, I assume Black Bullheads. The young school together while the adult male stays close by to protect them. There were many broods of these little fish in Cattail Marsh.


I haven’t learned to ID the local dragonflies, so if you know who this is, leave a comment.

And More Shorebirds

Another quick trip to Fernhill Wetlands this afternoon produced a couple of species that were not present a few days ago.


A Long-billed Dowitcher (left) and a Pectoral Sandpiper. Both birds are in juvenal plumage, indicated by the pale edges on the scapulars and wing coverts which create a scaly pattern. The Pectoral has a clump of mud on the base of his bill.


Another view of the Pectoral Sandpiper with two Long-billed Dowitchers. The crouching posture suggests that the bird is on alert and ready to flush. That is a good clue for the birder to back off.


A Lesser Yellowlegs.

Shorebirds

The big news in Oregon birding this week is the Wood Sandpiper found at Fern Ridge Reservoir west of Eugene (Birding Oregon p. 90). This is the first record for Oregon, and one of only a few records for North America south of Alaska. Of regional interest was a Buff-breasted Sandpiper at Tualatin River NWR, just west of Tigard. I wasn’t able to chase either of these birds, so I had to settle for a few more common species at Fernhill Wetlands (Birding Oregon p. 61).


While we can’t see the bill on this individual, the bold stripes and orange tail identify this bird as a Wilson’s Snipe.


Here is a Greater Yellowlegs. The bill is more than half the total length of the head. On a Lesser Yellowlegs, the bill is about half the total head length, and the bird is considerably smaller overall.
