1. Twenty Years of Bird Monitoring and Habitat Management at Springbrook Prairie Joe Suchecki Site Steward

2. Why Monitor Birds  Obtain basic information on what birds are on a site  Identify key areas or habitats for protection  Monitor population trends  Determine habitat preferences  Observe changes in response to management

4. Why Monitor Birds  Obtain basic information on what birds are on a site  Identify key areas or habitats for protection  Monitor population trends  Determine habitat preferences  Observe changes in response to management  Evaluate Initial Conclusions

8. Grassland Birds  High Grassland Bird Populations  Nesting Short-eared Owl, Northern Harrier, Upland Sandpiper, Henslow’s Sparrow  Complete Suite of Grassland Birds –Sedge Wren, Grasshopper and Savannah Sparrow, Dickcissel, Bobolink, Eastern Meadowlark –Ring-necked Pheasant, Song Sparrow, Common Yellowthroat, Red-winged Blackbird –Clay-colored Sparrow

9. Bird Monitoring  21 Point Counts 1994-2014 –Same Location –Same Observer –Consistent Method/Times  4 Transects 1980’s-2014 –Early scattered data –Different Observers  Walking Around – Weekly birding

11. Three Topics Today  Changes in Grassland Bird Populations at Springbrook Prairie over 20 years  How has site management and restoration affected grassland birds  Review validity of initial conclusions regarding birds, habitats, and restoration

12. Grassland Birds  True Grassland Species  Sedge wren  Dickcissel  Savannah Sparrow  Grasshopper Sparrow  Henslow’s Sparrow  Bobolink  Eastern Meadowlark  Others  Red-winged Blackbird  Common Yellowthroat  Song Sparrow  Field Sparrow  Ring-necked Pheasant

13. Overall Grassland Bird Populations  Transects can supply an indication of overall population changes at Springbrook –Cover large areas –Samples most habitats –Provides Information on most species  Combined data from all four transects from 1994-2014 used for the following results.

15. Springbrook Bobolinks

17. Springbrook Sedge Wrens

19. Springbrook Henslow’s Sparrows

21. Springbrook Savannah Sparrows

22. Springbrook Grasshopper Sparrows

24. Springbrook Red-winged Blackbirds

27. Grassland Bird Trends 1994-2014  SPRINGBROOK  Eastern Meadowlark +4%  Red-winged Blackbird +35%  Bobolink +57%  CommonYellowthroat +263%  Sedge Wren +333%  Henslow’s Sparrow +1600%  Savannah Sparrow -9%  Ring-necked Pheasant -63%  Grasshopper Sparrow -96%  AUDUBON NATIONAL DATA  -71%  -21%  -51%  -149%  +88%  -96%  +8%  -51%  -65%

28. Point Count Data  Point counts provide Information on bird populations at certain areas or habitats  At Springbrook, 21 points representing different habitats and vegetation – 15 sample grassland  Three replicates at each point in June  Five-minute census time  All completed between 0445 and 0700

29. Initial Conclusions 1997-2002  Bird Populations Show High Annual Variation  Non-Native Grasslands Provide Good Nesting Habitat  Bird Densities Higher in Non-Native Habitat  Tree and Brush Removal Improves Grassland Bird Habitat  Restorations Dominated by Native Tallgrass Do Not Provide Suitable Habitat  Grassland Birds Decrease as Sites Restored  Short Grass Restoration May be More Successful

30. Bird Monitoring Results  Bird Populations Show High Annual Variations  Confirmed

31. Annual Variation in Bobolinks

32. Bird Monitoring Results  Non-Native Grasslands Provide Good Nesting Habitat  Confirmed
