Waldschnepfe
The male performs a courtship display flight called 'roding' at dusk between April and June. A mating call is performed during courtship display flights: "orr, orr, orr, pist". A study of spectrograms of the vocalisations of male Eurasian woodcock showed that 95% of calls could be attributed correctly to individual birds, and concluded that counting roding males was a suitable method of monitoring the population.
