|Eurasian Collared-Doves - by R. Matlack|
I had previously blogged about Eurasion Collared-Dove expansion in North America, but recent IBLE chatter got me wondering about how they have expanded across Idaho. Here is an animated map that I made using eBird reported sightings.
Some of this data may be slightly skewed due to increased numbers of eBird users in the last few years, but based on anecdotal evidence, the expansion of Eurasian-collared Doves pretty well matches what the animated maps are showing us.
Many birders, and even old-time farmers, express hatred and frustration at these new birds to our area. I'm not sure why they hate them? From what I can tell they aren't displacing any other species of birds, as do European Starlings. Perhaps they can be a nuisance like Rock Pigeons, but they seem to act more like Mourning Doves. If the reason for disliking them is that 'they shouldn't be here', well, neither should all the really cool vagrants that we get so excited about. Looks like we probably have more Eurasian Collared-Doves and more European Starlings than Europe does. Maybe its time to drop the geography from their names on the official bird lists in North America.
For what its worth...I think Collared-Doves are neat looking. They are larger than Mourning Doves, lighter in color. They also have the big white tail feathers which are fan-shaped in flight rather than wedge shaped. That black partial collar also distinguishes them from other dove species.
Anyway...we still may have a few more months or years before they are present across the whole Treasure Valley. I expect that they'll be at Avimor by next Spring.
