To compare traditional observer-based survey methods against automated acoustic classification via BirdNET for measuring bird alpha richness and beta diversity across breeding seasons.
Evaluated 97 10-minute surveys across three methods—in-person point counts, manual acoustic recording analysis, and BirdNET automated detection—in Białowieża National Park, Poland.
Analyzed continuous all-day audio recordings using BirdNET to assess cumulative breeding season species richness alongside short-term survey comparisons.
All-day BirdNET analysis detected the greatest alpha richness with 80 species, whereas short-term 10-minute BirdNET surveys detected 49 species compared to 61 species from manual recording reviews.
Beta diversity differed significantly according to the survey site and monitoring method employed (p < 0.05).
Short-term survey richness showed weak correlation with full-day automated acoustic analysis across methods (Pearson's correlation: 0.34–0.49).

Implication

Comparative field study reveals automated acoustic monitoring detects higher overall bird richness in a primaeval forest, suggesting all-day recordings improve long-term biodiversity surveys.
