Count (quantitative) methods in avifaunistics have been neglected in Slovenia for decades and have certainly not followed the development else-where. For e needs of nature conservation and of basic as well as ecological research, the bird populations should be counted and relations as to their numbers within communities astablished. The counting of breeding populations of separate, usually somewhat rare species has been relatively comprehensive and the only ones by which some favourable inceptions for more extensive regional or national monitoring have been set up. Among the methods involving the entire species spectrum, various transect methods, point counts, area counts and mapping have been mainly applied. The transect method during which the detectability decrease with the increasing side distance from the observer is taken into consideration is a possible alternative for the comparative studies. Due to its simpleness it is also siutable for more extensive monitoring and has been implemented in a number of countries. Point counts enable the greatest of mappings per time unit and very accurate descripton of the habitat around the mapping point. The territory mapping certainly remains the most accurate method (to the exclusion of the extremely time-consuming andin larger areas hardly feasible search for nests), and for this reason its unpopularity in Slovenia is unfounded. Competent commissions and boards shouldprepare some uniform recommendations for its use, such as have existed in many European countries for decades. The area count method with single or multiple counting and without territory mapping is extremely inaccurate and unreliable. It allows us to determine size classes for separate species at themost and is applicable only as a provisional measure for mapping of large areas in a single season.
