Jackson Bottom birds: June 4-10, 2010

Wet, wet, wet! Rain this week backed up water from the Tualatin River and refilled the wetland ponds at Jackson Bottom Wetlands Preserve in Hillsboro, Oregon.

Joe Blowers found a pair of WESTERN KINGBIRDS on June 5, a first-Preserve record of these migrant flycatchers that are rather uncommon in NW Oregon.

Another surprise, a migrant DUSKY FLYCATCHER was present June 4. This is the second-Preserve record following the first observation the first week of May. They are typically found in mountain scrub and clear cuts from the upper Cascades eastward.

Continuing the flycatcher thread, several OLIVE-SIDED FLYCATCHERS are still being seen and heard on the Preserve for the third straight week. These should breed up in the older forests of the Coast Range and are presumably just passing through as late migrants.

A drake BLUE-WINGED TEAL was spotted on June 8.

Many fledglings are out and about, being cared for by their parents out of their nests including CANADA GOOSE, MALLARD, KILLDEER, MOURNING DOVE, HOUSE FINCH, BUSHTIT, RED-WINGED BLACKBIRD, and EURASIAN STARLING. On the other hand, many AMERICAN ROBINS seem to be nest building again, perhaps their nests were destroyed by the recent unseasonal deluges.

Forty-four chicks were counted in the Great Blue Heron rookery in Owl Woods on about a dozen nests. Rick Balazs counts these regularly by looking down on the nests from the Hillsboro Landfill (no public access).
