Jackson Bottom birds: June 18-24, 2010

It's finally stopped raining! ...At least for a couple of days... Birds are busy with their family duties here at Jackson Bottom Wetlands Preserve in Hillsboro, Oregon.

One interesting species here at the Wetlands is the BROWN-HEADED COWBIRD. It lays its eggs in the nests of other birds and lets the foster parents raise their young. This week we've observed both LESSER GOLDFINCHES and HOUSE FINCHES with juvenile cowbirds following them begging for food--indicating two of the local host species so far.

A surprise bird was a YELLOW-HEADED BLACKBIRD that put in a brief appearance in the wetlands on June 23. There are no definite previous records for the Preserve. This species is a rare almost-annual late spring migrant in wetlands in Washington County.
