Grasshopper Sparrow

The grasshopper sparrow was the last bird I saw upon leaving Veracruz, and this painting is based off of sketches I did at the time.  They are another secretive grassland species, but nothing in comparison to the Botteri’s Sparrow.  They are more associated with species of bunchgrass, so can be seen a little more easily as they skitter around. 

 

On the whole, the Grasshopper Sparrow is pretty common, although like most grassland specialists declining.  There does exists an endangered resident subspecies of Grasshopper Sparrow that lives in Florida.  It is interesting to note that this Florida population has a large degree of genetic variability (according to Bulgin et al’s paper Ancestral polymorphisms in genetic markers obscure detection of evolutionarily distinct populations in the endangered Florida grasshopper sparrow,) and the group’s genetic distinctness is muddy at best.  This means that their status as a subspecies is based on (admittedly well-defined) morphological and behavioral characteristics.  This is a departure from the current standard of a purely genetic standpoint of what makes a distinct population, and it pleases me to see this.  In my mind, there is more that makes a species that genetic markers.
