Related Species

While most classifications have regarded Greater and Lesser yellowlegs as closely related species, the 2 constituting Ridgway’s (1919) genus Neoglottis, some evidence suggests the yellowlegs are not sister taxa. Comparison of skeletal characters led Nichols (1923) to question Ridgway’s segregation of the yellowlegs from similar Eurasian tringines (e.g., Common Redshank [T. totanus] and Common Greenshank [T. nebularia]), and a recent phylogenetic analysis supports placing Greater Yellowlegs as sister species to Spotted Redshank (T. erythropus) with Lesser Yellowlegs among an unresolved group of other tringines, including Marsh Sandpiper (T. stagnatilis), Common Redshank, and Common Greenshank (Chu 1995, reanalysis of J. G. Strauch’s osteological data).
