Participant or randomly-chosen, broadcast-assisted point counts focused on detecting secretive marshbirds (e.g., bitterns, rails).
Twice, or optionally three times, annually during the peak breeding season. Aim is to survey stations with at least 2 visits per year for multiple years.
Great Lakes basin, US and Canada
Primarily waterbirds
Data collected by MMP volunteers is used to determine long-term trends in species diversity, occurrence and abundance, and to directly inform and guide conservation, restoration and management programs for marshes and their bird and amphibian inhabitants.
Non-random, user selected wetlands, wetlands in Areas of Concern
Bird survey routes with 1-8 listening stations 250 m apart. Listening stations were 100 m fixed-distance point counts. Two visits, 10 days apart between 20 May and 5 July. Broadcast tapes used for 5 minutes followed by a 5 minute silent listening period
Data are reviewed by staff knowledgeable in the ecology and behavior of marsh birds.
