A. m. pelonota (the extinct Smyrna Seaside Sparrow, in northeastern Florida, formerly from Amelia Island to New Smyrna) A. m. pelonota Where do the isolated Florida populations fit in? Well, we don’t know about pelonota, the Smyrna Seaside Sparrow, and we never will. It is extinct. However, it was very like the other Atlantic Seasides in appearance, and was probably just an isolated population of macgillivraii. Many of us mourn the loss of a population. And while pelonota may have appeared to be much like all other Atlantic Coastal Seaside Sparrows, it was unique, and unique in ways that we now will never be able to know, because it is gone. We will never know more about its biology, and its loss also tells us that prime saltmarsh habitats in northern Florida, along with their associated biota, were greatly altered (see Kale 1996). A major culprit in this habitat alteration was the northward invasion of mangroves into the sparrow’s preferred habitat; the spraying of DDT for mosquito control may also have played a role in the demise of pelonota. On the whole, though, we don’t know much about pelonota or the natural community in which it was found. www.aba.org/birding/v37n5p490.pdf |

This subspecies is not reckognized by Hume & Walters (2012), HM4 or Birdlife/HBW.

From HBW Alive
Possible race pelonotus (perhaps no more than an isolated population of race macgillivraii) extinct since mid-1970s; formerly found in NE Florida (from Georgia–Florida boundary S to New Smyrna).
I think moving should wait until DNA analyzes confirmed its invalidity.

Yes but it still isnt reckognized www.hbw.com/species/seaside-sparrow-ammodramus-maritimus simply raising the possibility that it may be valid. Hume & Walters (2012) does not even mention this subspecies in the invalid chapter. |

It is indeed most likely not a valid subspecies, but for now we can leave it here as there are sources that still recognise it, like: Gill, F and D Donsker (Eds). 2014. IOC World Bird List (v 4.2). Doi 10.14344/IOC.ML.4.2. www.worldbirdnames.org/. |
