Nelson's Sharp-tailed Sparrow

 I have some trouble keeping up with the name changes some species have undergone in recent years. This is one example. I just referred to them as Sharp-tailed Sparrows in the past or possibly Acadian Sharp-tailed Sparrows if memory serves. Now I don't know whether to refer to them as just Nelson's Sparrows and leave out the sharp-tailed bit. The more southern species is or was known as the Saltmarsh Sharp-tailed Sparrow which is a little confusing since this one is also found almost exclusively in salt marshes. I photograph them in almost the exact location from one year to the next which as you may have guessed is in a salt marsh.
