1. Citizens Behind the Science: The Use of Citizen Volunteers in Urban Bird Research William P. Mueller WI Society for Ornithology WI Bird Conservation Initiative Timothy L. Vargo Urban Ecology Center Owen D. Boyle WDNR

2. Some of the most effective studies of bird species and changes, such as population declines, begin with a discussion of birds in the landscape… An urban bird study - - -

3. Changes in the landscape: fragmentation (Curtis 1956)

4. Patches of habitat in urban areas are surrounded by areas much less suitable for bird use

5. Milwaukee County’s parks comprise a fragmented set of habitats for migrating land birds…

6. …BUT, these fragmented woodlands can be vital refuges for migrants!

7. Milwaukee County Avian Migration Monitoring Partnership (MCAMMP) Project Goals: 1.Assess bird use of small habitat patches in an urban matrix 2.Sampling & analysis of differences in vegetation that help to explain #1 3.Determine refueling rate of migrants in variable patch types, and thereby measure habitat quality 4.Train and utilize citizen scientists to accomplish these research goals and establish a long-term Citizen-based monitoring program

8. Importance of this research Migrants utilize a variety of stopover sites One often-neglected set of sites are in urban areas Urban habitats include parks and natural areas, often characterized by some degree of disturbance This is one of the first studies nationwide to focus on how refueling rate and body condition are affected by quality of urban stopover habitats

9. Components of the MCAMMP Project GPS mapping of sites Transect counts of species on each site Study design/ site selection Vegetation sampling protocol Mistnetting and banding of migrants and blood sampling of target species Environmental education: students and citizen scientists

10. All study sites and transects were GPS’d, and mapped on aerial photos

13. MCAMMP Transects 250 m in length X 40 m in width Data on all species found, weather, time of day and duration of transect, degree of leaf development in canopy 8 study sites in 2006-2007; 4 additional sites in 2008

14. In the first 2 field seasons, ~90 species were found on transect counts, including: 2 forest raptor spp.3 wrens Black-b. Cuckoo5 thrushes, B.-g. Gnatcatcher Gr. Horned OwlC. Waxwing 4 woodpeckersBr. Creeper 7 flycatchers4 vireos 5 swallows23 warblers Am. Crow & Blue Jay 2 grosbeaks, Sc. Tanager, Indigo Bunting Black-c. Chickadee & White-br. Nuthatch 4 sparrows, 3 blackbirds & Baltimore Oriole

15. The Plan: –Volunteers seek certification by the Wisconsin Birder Certification Program (Bob Howe, UW-Green Bay) Volunteers and the Transects The Reality…

16. MCAMMP Vegetation Sampling

17. Vegetation Sampling: Questions What are the differences in the vegetation between sites that could explain differential bird use? –Plant species composition –Vegetation structure How is habitat quality affected by the presence of invasive exotic plant species?

19. Vegetation Data Collection What are the differences in the vegetation of sites that could explain differential bird use/ refueling rates? –identify species –relative abundance/ % cover –canopy closure –bare ground/ leaf litter

20. Vegetation Data Collection How is habitat quality affected by the presence of invasive exotic plant species? –abundance of dominant exotics  correlation with site use (transect/ banding data) or bird condition (blood analysis)?

21. Challenges of sampling vegetation No trails! (buckthorn/ honeysuckle thickets, steep-sided ravines) Longer hours/ field season Random sampling with citizen scientists

22. Data collection assistance –data recording –plant I.D. –estimating percent cover/ canopy closure –tree measurements Doubled the number of teams (data collected) per day with citizen scientists Benefits of sampling vegetation

23. MCAMMP Mistnetting and Banding

24. MCAMMP banding program Pilot Year: Two Stations - Riverside & Kletzsch Parks Two teams banding on same day for comparison Blood sampling of 7 target species: –Seed-eaters: SCJU & WTSP –Frugivores: SWTH & HETH –Insectivores: AMRE, YRWA, MYWA

38. In the first two field seasons, 44 species were banded, with blood samples taken from all 8 target species. Ruby-throated Hummingbird 2 kinglets 4 woodpeckers Brown Creeper 1 flycatcher 4 thrushes 1 swallow Gray Catbird 2 vireos 11 warblers Blue Jay 5 sparrows Black-capped Chickadee 2 grosbeaks & Indigo Bunting White-breasted Nuthatch 3 blackbirds House Wren Am. Goldfinch

39. ASSESSING RATES OF FUEL DEPOSITION AND STOPOVER HABITAT QUALITY FOR MIGRATORY BIRDS Christopher G. Guglielmo University of Western Ontario

40. Circulating lipid metabolites reflect the metabolic state of migrants TRIGLYCERIDE B- OH- BUTYRATE METABOLITE FEEDING FASTING

41. Metabolite profiles change rapidly after a change in feeding rate in Wilson’s Warblers (Wilsonia pusilla). Zajac et al. 2006 JAB 37:405-408 ** *

42. MCAMMP: blood sampling

43. A very small blood sample, taken from the brachial vein (sample size varies in relation to size of bird)

44. Blood Sampling: Questions How do migrants fare on small habitat patches in an urban matrix? How effectively can they re-fuel?

45. The Volunteer Training Process: Creating an MCAMMP Citizen Scientist Volunteer workshop –Recruiting: introduction to the project partners, goals, and volunteer opportunities Detailed training in the field On-the-ground experience Opportunities for team building – picnics and parties!

46. MCAMMP Volunteer and Intern Effort (2006-2007) Project Component Volunteers & InternsHours $$ saved ($15/hr. for field assistants) Transects15121$1,815 Vegetation16134$2,144 Banding931,420$21,300 TOTAL1241675$25,259

47. Benefits  Increases data-collection power  Cost-effective alternative or addition to paid assistants  Local support & “ownership”  Data usually same quality as paid technicians  Citizen scientists gain an education and learn skills to carry with them  Citizen scientists gain an appreciation of the natural world and conservation  Volunteers have unique talents that can help in unexpected ways Challenges  Limited volunteer availability (jobs, family, etc.)  Increased time and effort of training and coordinating schedules  Often requires technical skills and knowledge of species identification which may seem daunting  Physically demanding conditions/ long hours Vargo et al. (in press)

48. The most extraordinary thing about the MCAMMP project is simply its people.

49. Volunteers and visitors are not always students…

51. …but many are: MCAMMP’s environmental education component

53. A bird in the hand is…priceless!
