MRBO has been banding Northern Saw-whet Owls in central Missouri since 2010 and in Arrow Rock since 2014.  Each fall we welcome visitors to our office during the nights we attempt to catch this small owl during its migration season.  In 2018, we hosted over 100 visitors, most of whom got to see an owl despite it being a very slow year for us in terms of owl captures.  Please see the data for our past few seasons below, and watch MRBO’s Facebook page (facebook.com/moriverbirdobs) next fall if you would like to visit!
