Over the last few days I have been attempting to make some recordings and sonograms of Redwing flight calls. This is easier said than done at a semi-urban watchpoint like Lutley Wedge! Conditions have to be just right, i.e the birds have to be migrating reasonably low overhead, on a day without too much wind noise for the mic, too many car alarms going off, police sirens, shouting/whistling dog-walkers, barking packs of out of control dogs, pneumatic drills from nearby road works etc etc!
Below are two examples from some of the thousands of Redwings that have been migrating overhead during the early morning skywatches. To me, the thin 'seeep' call of nocturnal migrating Redwing at night is one of the most evocative sounds, and something I listen out for every autumn. 'Non-visable acoustic migration'!
