影音備註
Some wind noise but can clearly hear both WEGR (double-syllabled "kreet-kreet" calls) & CLGR (single-syllabled "kreeeeed" calls), both seen here in good numbers.
觀察細節
Scanned lake from shoreline and above, estimates 125 Aechmophorus grebes, with estimate of about 4:1 WEGR to CLGR based on individuals close enough to separate.
