WBCI Approach to Bird MonitoringWBCI Approach to Bird Monitoring
1. Monitoring is integral to “strategic conservation”• Strategic conservation – a structured way of thinking about
what we do and why we do it• Monitoring programs should address explicit questions aimed
at improving conservation efforts for birds of concern

WBCI Approach to Bird MonitoringWBCI Approach to Bird Monitoring
1. Monitoring is integral to “strategic conservation”• Strategic conservation – a structured way of thinking about what we
do and why we do it• Monitoring programs should address explicit questions aimed at
improving conservation efforts for birds of concern
2. Monitoring should be conducted in coordinated fashion across the biological range of a species or group of species
• Aligned objectives, standardized protocols, central databases etc.• Statewide Coordinated Bird Monitoring Plan
3. Bird monitoring has benefitted from, and is dependent on, contributions from non-professionals
• Data generated by volunteers is used for conservation• Communicating results• WBCI training opportunities

Early WBCI monitoring efforts have focused on filling gaps in statewide surveillance monitoring efforts
= Identifying species at risk

Western Great Lakes Owl Western Great Lakes Owl Monitoring ProgramMonitoring Program
• Owls are poorly monitored – nocturnal, secretive, etc.
• Surveys initiated in 2005 in cooperation with HRBO
• Objectives:– Status– Distribution– Trends

Owl Monitoring Owl Monitoring - Methods- Methods
• Randomly-selected roadside survey routes statewide
• Surveyed once after dark from April 1-15
• 10 stops per route, each 1 mile apart
• 5 minutes per stop
• No playback / broadcast
• Record owls and basic weather data
• Certified observers

Nightjar SurveyNightjar Survey
• Anecdotal evidence suggests declines• BBS data is incomplete but also suggests significant nationwide
declines (-2.1% per year for Whip-poor-wills)• Atlas data from second Atlas efforts suggest systematic declines• Wisconsin Species of Greatest Conservation Need

Nightjar SurveyNightjar Survey
• Started here in WI in 2007
• Joint effort between NE CBM and SE PIF
• Goals = assess distribution, status, trends of CONI and WHIP
• Data will also be used for region-wide modeling efforts to assess conservation areas for species
![Page 14: Monitoring Birds in Wisconsin An update on new surveys and how to get involved Ryan Brady and Andy Paulios (WI-DNR) October 25, 2008](https://reader035.vdocument.in/reader035/viewer/2022062417/5517c506550346892b8b4b27/html5/thumbnails/14.jpg)
Nightjar Survey - MethodsNightjar Survey - Methods
• Very similar to owls
• Sign up for pre-established roadside route in your area
• 10 stops per route, 6 minutes per stop
• Passively listen and record nightjars (and owls)
• Routes are run once in late May and June NEAR TIME OF FULL MOON (e.g. June 11-26)
