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

Coordination in ActionCoordination in Action

Early WBCI monitoring efforts have focused on filling gaps in statewide surveillance monitoring efforts

= Identifying species at risk

Priority Monitoring Gaps

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

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)

Nightjar Survey – 2008 ResultsNightjar Survey – 2008 Results

• 71 of 92 routes run

• 45+ volunteers

• Total birds:– WHIP…..172– CONI……9– BDOW….36– GHOW….12– LEOW…..1

Distribution of Whip-poor-willsDistribution of Whip-poor-wills

Many WHIPs:

• NW Sands• NE Sands• Central Sand Plains• Northern Highland (lower)

Some WHIPs:

• Central Sand Hills• Western Coulee & Ridges• Forest Transition• North Central Forest• Superior Coastal Plain

Few to none:

• All the rest

SECRETIVE MARSHBIRDSSECRETIVE MARSHBIRDS

Survey ObjectivesSurvey Objectives

1. Estimate population trends for marshbirds

2. Inform habitat management decisions

3. Provide status data for harvested species

ConwayConwayProtocolProtocol

• May/June

• Morning or evening

• 2-3 surveys per year

• PLAYBACK

• 5 minutes passive, then 1 minute per broadcast species

• Record target species

Marshbirds – 2008 Prelim ResultsMarshbirds – 2008 Prelim Results

• Hybrid model – 3 field techs + ~30 birders and biologists• Training workshop at Horicon Marsh• ~325 points surveyed over ~55 routes statewide• Most common: Sora, Virginia Rail, Amer Bittern• Several King and Yellow Rails detected• Data also collected on secondary target species
