Poznámky
The bird pictured in ML430758481 produced these sounds, which are periodically frequency-modulated downslurs. The vast majority of sounds produced by the flock in flight were of this type. The digital-8 tape was played on a Sony GV-D200 deck and the digital recording was ported to a HP laptop, via a firewire connection, where it was captured with Corel Video Studio software. The soundtrack was exported to wav file, and was edited for upload with Signal Sound Analysis software.
Podrobnosti k pozorování
On the summit. frame by frame analysis of video of fly-by confirmed 17 individuals, but 20-24 more likely real number. Downslurred calls recorded are not well-represented in ML, but then most of those samples were recorded in winter. A similar sound in breeding season, and not too far to the north, is ML165790161.
