Observasjonsdetaljer
At least! At boat ramp with grackles and red winged blackbirds. The photo of Merlin shows the spectogram at 21 seconds because it illustrates for me the difference between the rusty and redwing blackbird ‘sigh’. The latter is the higher-pitched sound and follows the rusty sigh at a lower pitch.
