    Surveyors experienced at identifying birds by sight and sound are needed to adopt a site and lead surveys. 

    Survey goals 

    Birds indicate the health of Gresham’s land and water ecosystems.

    • Staff use the survey information to develop strategies to support native birds.
    • Knowing what bird species live in Gresham helps our habitat stewards know where and what kind of bird nest boxes to install. 

    Findings

    In 2015, community volunteers revealed bird species living in Gresham, including:

    • Native woodpeckers, ducks, hummingbirds, and raptors (birds of prey).
    • Two non-native, invasive species – European starlings and house sparrows.
    • Two species on the state listed species of concern – Pileated woodpecker and Olive-sided flycatcher.

    Background

    An AmeriCorps volunteer developed the first bird survey protocol for the City in 2009. The first survey was conducted by 14 community volunteers, at 44 sites, including 14 in Gresham’s natural areas.
