Sumas Old Customs House


This is the oldest historic roost site in the state.  North and southbound observations made by North Cascades Audubon, Joe Meche, coordinator, had 13 observations in 2008 northbound with 6,785 Vaux's /chimney interactions. There have also been interest and observations reported by the BC Central Valley Naturalists Society led by Alice Roos.  They figured out that you could get a good look at the goings on without crossing the border.
