Nocmig

Shorthand for noctural migration, it has become quite the thing in these covid times in the birding world. Basically you record through the night and then try and identify the various species that have flown over your microphone.
It has provided a few surprises including a lot of unexpected species occuring with considerable regularity.
It is however not easy trying to identify calls without any idea of the sort of bird one is considering and I have struggled. Any knowledgeable person who knows what this might be is very welcome to tell me as I really don't have a clue! This link should take you to the sound as well as the sonogram to make it (a little) easier.
