You’re likely to see Eurasian collared doves on a good pigeon shoot—we certainly did. These birds are similar to mourning doves in many ways (they’re pretty damn good wrapped in bacon too). Adults sport a black ring at the nape of the neck (hence the name), and they make a harsh, distinctive reeaaa call. For hunters, the most important difference is that collared doves were introduced into the U.S. by mistake in the ’70s, and have colonized so quickly that they can now be found all over the country, with the exception of the Northeast. They’re considered an invasive species, and in most places, you can hunt them year-round without a bag limit. But on a summer pigeon hunt, you must be absolutely confident in your dove ID. Blasting a mourning dove by mistake during a pigeon shoot in July is a serious game violation.
