Surveys of Grassland Birds at Marsh-Billings-Rockefeller National Historical Park: 2010-2016 Summary Report
Jones K. 2016. Surveys of Grassland Birds at Marsh-Billings-Rockefeller National Historical Park: 2010-2016 Summary Report
Grassland birds are of regional conservation concern because available habitat has declined due to land development, grassland succession to shrub and forest, and more intensive agricultural mowing practices (various obs.). This project surveys Marsh-Billings-Rockefeller National Historical Park (Park) grassland bird populations. The NPS inventory and monitoring project surveys forested habitats and only coincidentally surveys Park grasslands. Previous data show that Bobolinks, detected in the Breeding Bird Inventory (Faccio 2003) and the early years of breeding landbird monitoring (2006-2007), were not recorded after 2007 (Faccio and Mitchell 2015). By focusing exclusively on grassland habitats this survey more reliably detects changes in grassland bird populations in the Park. This report covers the years 2010-2016.
