註釋Presents papers from a symposium intended to draw together work being performed in Canada related to the monitoring of bird species ranging from sea birds and waterfowl to migratory and resident land birds, with emphasis on the role of volunteers in many monitoring programs. The papers cover all the major, broad-scale multi-species monitoring programs in Canada aimed at tracking changes in species abundance. The first few papers deal with monitoring of aquatic birds, monitored by government agencies, with the remainder of papers dealing with land birds, migratory birds, and wintering birds. The final paper provides an overview of land bird monitoring in Canada both by government and non- governmental organizations.
