Identification of characterstic non-vocalisation bird sounds.

[TimYang-jpg]

Hello from New Zealand,
I've been playing with your software and a bird recorder to do some avifauna surveys.
However I ran into a curious issue where one of our native bird species Kererū/New Zealand Pigeon (Hemiphaga novaeseelandiae)
Could not be detected as they don't necessarily make any vocalisations, however they make a very characteristic noise when they take flight. I used some files uploaded on xeno-canto and the BirdNet-Analyzer program could not identify the noise. I'm just curious if there are plans/ideas on how to deal with very characteristic noises that birds make which allow them to be identified by person but not the model.

Thanks
