Jackson Bottom birds: May 21-27, 2010

Lazuli BuntingLazuli Bunting, Jackson Bottom Wetlands Preserve, Hillsboro, Oregon on May 24, 2010 by Greg Gillson.


The final new expected migrant bird species of spring arrived this week at Jackson bottom Wetlands Preserve with sightings of LAZULI BUNTINGS on May 24 and WILLOW FLYCATCHER on May 25. Both will spend the summer and breed locally.

A rather unusual migrant species showed up May 24 and May 26; a single OLIVE-SIDED FLYCATCHER on these days. These larger flycatchers are uncommon but regular in higher forests, and are infrequently spotted in the lowlands during migration.

SWAINSON'S THRUSHES and WESTERN-WOOD-PEWEES arrvied in larger numbers this week. The bird feeders are supporting good numbers of LESSER and AMERICAN GOLDFINCHES and BLACK-HEADED GROSBEAKS.

Fledgling EUROPEAN STARLINGS, WESTERN SCRUB-JAYS, and SONGS SPARROWS were noted this week, confirming breeding on the Preserve. These are not a surprise, but breeding birds have not been tracked specifically before this spring season.
