Eurasian Collared-Dove Expansion in Idaho

Eurasian Collared-Doves - by R. Matlack
When we first moved back to Idaho three and a half years ago, Eurasian Collared-Doves were just starting to be noticed in the Treasure Valley area of Idaho.  I lived in Star, Idaho at the time and about 8 miles west was a reliable spot to see them in Middleton at the Oregon Trail Church.  About a year and a half ago, we moved to Avimor, in the foothills north of Eagle and Boise.  I've been wondering how soon I'd see Eurasian Collared-Doves at Avimor.  Well...they are very close now.  For the last couple of months I've been seeing a couple of them on Beacon Light Rd, close to Highway 55.  That means they are now only about 5 miles away.

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.

The animated map below is focusing only the the Treasure Valley area of Idaho, specifically Canyon and Ada Counties.  Watch for my E. Collared-Dove sighting north of Eagle to pop up on the 2010 map.

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.

  1. nice post - we have one as a pet - given to us by museum that rescues them and needed help with housing them.

  2. Wow, very dramatic presentation. I have yet to see one in my neighborhood/hulls gulch, but it is only time. Also, in all my time out in the mountains this summer, I didn't see in more than 5 miles form town.

  3. We were very excited when we saw them in Idaho Falls a couple years ago. Only to find out they're not supposed to be there. But I think they are neat, I love their collar. We have quite a few of them here in Star Valley, and it reminds me of 'home'. As always, awesome pictures!

  4. Collared Doves have a very large population here in the UK after colonising abot 50 years ago, but they are not considered a pest species. If they are as successful in the US their numbers will expand quickly.

  5. We live just south of Greenleaf & a pair showed up here today. I think they're beautiful & welcome them!

  6. There are several pairs that visit my feeders here in Nampa. A novice bird watcher, I thought they were a type of mourning dove at first until I found a picture of them and this blog.

  7. I know this won't be popular but I have to say it. The term "invasive species" is used with animals, birds, trees, plants, weeds, fish, etc. The term seems to imply that at some point in time everything that was "here", where ever "here" is, is "okay", but anyting coming into the area later, is invasive. I just don't understand the thinking. It seems that every species and ecosystem is evolutionary. Even the plates on the earth move and change the ecosystems ever so slightly as the plates move. We may not like a "zebra mussel" or asian carp moving into our waters, and I'm not against keeping them out of some water, but to say they, or asian doves, are not "supposed to be there" or are invasive, just doesn't compute with me. I'm looking at Asian doves out my window right now and appreciate their beauty. Natural migration, or invasion? I just don't know.

  9. Well, just spotted my first one here in Boise today. Think they are quite a fine looking bird, and seem to play well with others.

  10. We a ton of them out in Parma you can see them about every where. They have the voice you expect to here but also make a crow like sound. They come to our feeders regularly. They bigger hope they eat as good as mourning doves. I'll find out this fall. They live in the same place year round they don't seem to migrate.

  13. We have positively identified at least two nesting pair in Riggins. One pair in my back yard pine tree, and another pair near the elementary school. They are lovely to watch.

  15. I started noticing the sound of something akin to pigeons but weren't that as I've raised pigeons growing up and It wasn't that sound. Just similar. I could not ID them for a while till I spotted a pair a few months ago. They were gone before i could get a good look at any markings other than they were light grey and had slender necks. Through all the searches I've found I'd noticed they looked rather close to Mourning doves- but till I found this- i wasn't sure what they were. so glad to know. So far I"ve only ID'd them with two distinct calling sounds and have noticed in the last Two years at least their population around my area expounding. I live on a riverbend thats a Very common rest stop for geese,ducks,heron etc and this year the calls of these birds have just driven me nuts Lol. They start before dawn and continue long after dark. Makes me miss the owls that left once this group became prevalent. On the other hand they seem to have chased off the starlings I have battled with for years - they were very skilled thieves of my cat food outside lol. Darn things would sit there and announce they were doing the deed- then squawk at the window when the dish was empty. Clever.
