Objectives: 1. Determine distribution of marsh birds within an area. 2. Estimate / compare density of marsh birds among management units, wetlands, or regions. 3. Estimate population trend for marsh birds at local or regional scale. 4. Evaluate incidental effects of management actions on marsh birds. 5. Document habitat types / conditions that may influence marsh bird abundance or occupancy. Survey Overview: Each survey consists of a 5-minute passive period point count and a broadcast sequence where all birds seen and/or heard using habitat are recorded. The passive period is followed by a broadcasting of a series of secretive marsh birds calls, in which a 30- second call is broadcast into the marsh, followed by a 30-second window of silence. This broadcast process is repeated for each secretive marsh bird species included on the broadcast sequence. Broadcast sequences vary from area to area.
