The purpose of the Lakeshore Nature Preserve Breeding Bird and Habitat Study is to identify the birds likely to breed and their habitat preferences in the Preserve from 2013 to 2015. The results will be compared with the baseline 2000 to 2002 results from the Breeding Bird and Habitat Study (Fall 2001 FCNA News, pages 2 and 5) to see if there have been shifts in breeding birds over the last decade due to habitat change or bird population changes. The project will determine the bird species in the various areas of the Preserve, their approximate numbers, and confirm the breeding of each species, using the methods of the Wisconsin Breeding Bird Atlas.
The breeding birds of the Preserve have changed little between 2000-2002 and 2013-2015. Common birds stayed common and rare birds remained rare. Despite restoration, neither grassland nor savanna bird diversity has increased. The number and species diversity of marsh birds have declined, possibly due to declining habitat quality in the Class of 1918 Marsh.
The observations are grouped in two charts.
