[Maine-birds] wind impact on songbirds, particularly flycatchers

Hello all,
Have you noticed that in general the average velocity of breezes/wind is higher and the duration of strong breezes/winds is longer recently? (Is there a name to quantify this magnitude/duration phenomenon?) I assume it's related to global warming/climate change and the generally more powerful movements of air due to temperature differences, etc.
I wonder how this is impacting our songbirds, particularly flycatchers. We have had few of those "lazy days of summer" with insects floating in the air and phoebes snapping them up. The drought has impacted insect numbers of course, but what about the wind's impact on predator success?
Is anyone studying this?  Is there a way to contribute useful observations? Or do you think nothing is amiss?
Feel free to respond offline if you don't think this is of broad interest.
Thanks,
Cathie Murray, Hallowell
