Comments about White-browed Woodswallows feeding at the weather front are interesting grist for my birdwatcher’s mill.
Often, during the warmer months, when conditions are completely still and the barometer is falling, I’ve noticed there’s a sudden upsurge in birds’ activity. They appear
to be chasing insects drawn into activity under the aforementioned conditions but, as old Julius Sumner Miller would have said, “Why is this so?”
I wonder why the change in atmospheric pressure brings the insects out and about when it would appear safer for them to bunker down until the impending weather passes?
