[Tweeters] When do Eurasian Collared-Doves start nesting in Washington?

Is there any evidence that Collared Doves compete most directly with
Mourning Doves? My casual and totally unscientific observation has been
that Collared Doves appear to have the potential to affect California Quail
more than Mourning Doves. I don’t often feed the birds, but I’ve noticed
that, when I put food out in winter, the Collared Doves scarf down the
larger seeds that the California Quail used to get. I’m not sure, but I
think my yard population of California Quail may have declined a bit in the
last 2 or 3 years since Collared Doves became permanent residents.

Ed,

Eurasian Collared-Dove are prolific breeders capable of nesting just about
any time of the year in Western Washington. They could easily raise FOUR
BROODS of 2 squab each in our area, and maybe more. In the Carnation area I
saw just fledged birds in March at the earliest and around Nov 1 at the
latest. They are different than our native Mourning Dove in that they
frequently use house eaves, ledges, and other man made structures on which
to build their typical flimsy stick nest lined with grass, moss, or even
nothing. They also frequent feeders and nest in suburban yards near food
sources, typically building nests in evergreens on brandh forks. Birds are
capable of breeding at 4-6 months of age, but are most productive after 1
year. This invasive species has the capability of overwhelming our native
doves - Mourning and White-Winged Doves in particuar use similar habitats
and reproduce at a slower pace. How fast does the population grow? ECDO
can go from egg laying to flight in 33-36 days depending upon conditions -
they are capable of feeding on their own at about 28-30 days after egg
laying. Typical incubation time is 17 days and it takes them 16-19 days to
fledge after hatching. Hope you get some great data about the population
here.

I’d like to watch in an area on Vashon to see if we can confirm breeding
this year.
