Vet du vilken art du såg:


Vad observerade du?
Annan (Vad observerade du?)
Bats flying around outside my house in the evening between my house and the water, presumably catching insects. They look like small swallows, and for a long time that's what I thought they were (until I realised it was too late in the evening and they were flying very fast). I've seen them here from time to time for years.
Kan du ge mer information om observationen, t.ex. beteende, livsmiljö etc:
