continuing on with the black oystercatcher conversation... Audubon Society of Portland and partners re-initiated Oregon coast-wide monitoring of oystercatchers a few years ago. Folks like Linda Fink have been instrumental in helping us conduct abundance surveys and nest monitoring and keep tabs on this species. Over 70 volunteers and agency folks have contributed to this effort since 2015. The current population for Oregon we estimate to be around 500-600 individuals. Here is a link <https://audubonportland.org/files/citizen-science/updated-black-oystercatcher-report-2016> to a recent report. This is up a bit from an estimate of ~300 in 2006 - last time there was a rigorous population estimate (by USGS). The bottom line is that although this species appears to be stable and potentially increased from the mid 2000s it has a small vulnerable population in Oregon. I won't get into the Peregrine Falcon scapegoat game but another stressor for this bird is increasing human (and dog) disturbance - particularly at nest sites. Right now there is a public process going on to update the rocky shores chapter of the Territorial Sea Plan - the guidance document for management of Oregon's coastline and state waters. There will be opportunities for public comment and increased protections of our rocky shores (and oystercatchers). Here's a link to the rocky shores process <http://www.oregonocean.info/index.php/tsp-rocky-shores-amendment>so you can get engaged.
