Observasjonsdetaljer
Recorded one higher pitched squeaky-sounding honk. See middle of linked audio clip. The fundamental frequency of that honk is significantly higher than all of the other sounds recorded, at 900-1000Hz. The other Canada goose honks have a fundamental frequency of 500-600Hz. I want this to be the cackling goose, but honestly I'm not sure! Going to have to try to find it again tomorrow.
