This review presents our current knowledge on automated methods for acoustic recording of calls and songs of birds. Acoustic long-term recordings can serve as a basis for an automated bird census. We stress the question of whether sound recordings are suitable for qualitative and quantitative analysis of bird populations. Special attention is devoted to autonomous recording methods and the evaluation of long-term recordings by use of acoustic pattern recognition algorithms. Realistic scenarios for the use of automated methods in field ornithology we see in the investigation of nocturnal bird migration, the census of nocturnal bird species, and data collection in core areas of nature reserves.
