Hi Fred. I think food is scarce for all wild animals this year due to the weather making certain plants unable to grow. Maybe the rock doves were after dragon flies but they all flew to the same spot. Desperation changes a lot of behaviors. Squirrels are missing their acorns for the second year in a row due to poor acorn production; also scarce horse chestnut production. Everybody seems to be scrounging. No blue jays until recently, only 1 or 2 turkey vultures where we used to have lots more; less great blue herons and no great egrets or green herons here at all this year so far.
And yes we do have very large predator fish that go after the ducks.

This time of year I see giant Mantids (non-native) and those Brown Marmorated Stinkbugs (also non-native) starting to come around again. I also never thought of Rock Doves as big insect eaters ‘tho. Who knows...Maybe they've got a taste for Mullet or Goby chased to the surface by other predators?
