There was a good movement of nighthawks along west bay shore in Oconto county,
several hundred in less than half an hour.
They aren't eating dragonflies, but both are catching other insects, mainly
flying ants recently although there has been a few chironomid hatches with
recent rains too.
There are really good dragonfly migrations along Green Bay and Lake Michigan
shore in August and September, mostly the larger Darners; Green, Canada,
Green-striped... Nighthawks don't eat them (to large), but Merlins, male
Peregrines often pick them off in flight and feed on the wing. The dragonflies
also get caught up in thermals used by the kettles of Broad-wings, who will
also feed on them on the wing! If you watch a swirling kettle, you will often
see an individual do a side slip and then the foot go up to beak. Munching
along as they float south.

Nighthawks - dragonflies
Interesting about dragonflies in the skies with the nighthawks.
That was what I saw in the past near Labor Day along Lake Michigan.
Are they following/eating the dragonflies?
Meadowlarks - grass cutting
Also interesting about the late meadowlark. How often does that occur?
Maybe the grass cutting guidelines are not that helpful for grassland birds?
Or grass cutting in early July may cause late meadowlark fledging?

Here in Iowa County 17 Common Nighthawks and a fall plumage Bobolink
were this evenings highlights. The sky was also full of dragonflies.
Also noted was a recently fledged Eastern Meadowlark. Glad I waited
until late August to hay the fields!
