Shai, thank you for the photos. Variations within this species really run along a wide spectrum. The breast of the bird on photo P1030904 is almost like a Nelson's Sparrow's. And yet there is no structural visible differences between the LI birds photographed. We can safely say that the Seaside Sparrow (complex) is not a ring species.
