Book Description
This report on avian plot methods is provided as Section 6.3.3 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 plot methods to estimate the density and diversity of bird populations for planning, management, and research purposes. Plot sampling in performed by a stationary observer who stands at each sampling point and records detections of birds in all directions during a fixed sampling period. The method is particularly suited to small or irregular study areas or where terrain is too rough for the use of transects. Plot methods can be used at any time of year. The report provides guidelines concerning plot establishment, sample size, survey timing and procedures, and interpretation of results, including and explanation and comparison of fixed plots and variable circular plots. Keywords: Avian survey and sampling, Bird populations, Plot methods, Population estimation, Variable circular plots, Wildlife management.

Book Description
This report on avian line-transect methods is provided as Section 6.3.2 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 line-transect methods to estimate the density and diversity of bird populations for planning, management, and research purposes. The basic line-transect survey involves walking a predetermined straight path and recording detections of birds along both sides of the line. The method is best suited to fairly large areas with homogeneous vegetation and gentle terrain, and can be used at any time of year. The report provides guidelines concerning transect establishment, sample size, survey timing and procedures, and interpretation of results, including an explanation and comparison of fixed width transects, Emlen's method, and a modified Emlen's method.

Book Description
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.

Book Description
A management techniques report on waterfowl nest baskets is provided as Section 5.1.3 of the US Army Corps of Engineers Wildlife Resources Management Manual. The report was prepared as a guide to assist Corps biologists and resource managers in developing and implementing waterfowl management programs on Corps lands. Topics covered for nest baskets include waterfowl use, design and construction, installation, placement, maintenance, costs, and cautions and limitations. specially designed wire fabric nest structures provide the means for potentially increasing breeding populations of waterfowl, especially the mallard (Anas platyrhynchos). The design, construction, installation, placement, and maintenance of four types of nesting structures are described. For purposes of this report, they are referred to as (1) open basket, (2) rectangular basket, (3) horizontal cone, and (4) horizontal cylinder. Detailed specifications and lists of materials required for construction are provided for each design. Recommendations are given for the proper placement and protection of nest structures in suitable habitat to ensure maximum use and productivity. (author).
