Bird survey methodology for Facilitators
See title in English.
Set length transects should be selected; the transects should be as linear as possible and in areas with good views of the surrounding landscape. A suggested length is 1km, but whatever length is selected, all transects should be the same length so as to be comparable. Transects should be split into smaller sections to make field recording easier, 100m is a suggested length of each section. Transects should be walked ideally twice each breeding season, once April to mid-May and once mid-May to end of June. Surveys should be started an hour after dawn, multiple surveys can be carried out in one morning but shouldn’t go beyond mid-morning. When walking the transect, any bird seen or heard should be noted, as well as any breeding behaviour such as singing, alarming, territorial behaviour, juveniles, nest building, chick feeding etc. Counts of each species seen should be recorded, and birds seen only flying over should be recorded separately. To make field recording easier, the BTO has devised a list of 2 letter codes for each species which can be used. If possible, each transect should be walked at the same slow steady pace with each section taking roughly the same amount of time. Each year, the same transects should be repeated to ensure the data is comparable between years to provide data on long term trends of populations. Surveys should only be carried out in favourable weather conditions. Avoid surveying in high winds, rain or poor visibility.
