Avian territory mapping : section 6.3.4, US Army Corps of Engineers wildlife resources management manual

This report on avian territory mapping is provided as Section 6.3.4 of the US Army Corps of Engineers Wildlife Resources Management Manual. The report is designed to assist the District or project biologist in the application of territory mapping to estimate the density and diversity of breeding bird populations for planning, management, and research purposes. The mapping method involves repeated visits to a relatively small study plot where observations of territorial songbirds are recorded on gridded maps. For each species, population density is determined by counting the number of occupied territories. The report presents guidelines concerning plot size and shape, plot maps, number of visits, survey timing and procedures, and interpretation of results.
