 The great-tailed greckle has expanded its range northward from Texas to Nebraska over the last four decades, while its closest relative, the boat-tailed greckle, has remained tied to the coasts of the Atlantic Ocean and the Gulf of Mexico as well as the interior of Florida. These two species differ in their habitat preferences, with the great-tailed greckle being able to inhabit a wider variety of urban, arid environments further away from natural water sources than the boat-tailed greckle, which prefers warmer, wetter, coastal environments. Additionally, the great-tailed greckle has shown greater adaptability to climate change, as it has been able to expand its range into new areas due to the availability of human-altered habitats. In contrast, the boat-tailed greckle has not experienced any significant range expansion despite similar climatic conditions. Our study suggests that the great-tailed greckle's ability to exploit novel habitats has contributed to its rapid range expansion, while the boat-tailed greckle's restricted range is likely due to its reliance on coastal habitats.
