Mourning Doves (initially one of the most regular
species in my yard), Collared Doves, and Coopers Hawks have been
in an epic battle in my yard for the better part of a decade
now. The Collared Doves originally arrived sometime around 2012,
2014ish and aggressively drove the Mourning Doves away. There
was a while when Collared Doves perched on every street light
along Independence and would gather in groups up to a dozen at a
time.
The hawks noticed soon enough and for a couple of years I'd see a Coopers Hawk several times a week, often eating a dove right in the middle of my yard.
The Collared Doves have thinned out now and
Coopers are uncommon again around here. This year I even had a
regular pair of Mourning Doves in the yard daily. I suspect the
struggle will continue since the Collared Doves are still around
and still aggressive. This has to have influenced other bird
populations too.
