Walking across the parking lot this morning, I saw a dove land to peck gravel. It looked bigger than our standard mourning dove, so I walked over to get a better look at it.
It looked like this. The Eurasian collared dove. It seems we've got a new species hereabouts. I don't recall seeing that distintive collar, but I was busy looking for wing and tail identifiers. The bird I saw in the parking lot was bigger than our mourning doves, was grey, and was smaller than the local pigeon population.
The Louisiana DWF website says this:
There are currently at least 5 other different species of dove breeding in Louisiana: Ground, Inca, white-winged, rock (common pigeons), and Eurasian collared-doves. The latter is an exotic that is rapidly spreading across the south. At this time, the impact of the Eurasian collared-doves on mourning doves is unknown. It is larger and more aggressive than the native mourning dove.Hmmm!
