Observation details

Photos - bird is darker mantled than Herring but lighter than LBBG - Odd primary plumage with adult like features but for the primaries. One mirror in left P10 and none on the right wing. Dark triangular primary wedge on each wing. Underwing marks more reminiscent of LBBG than Herring. Some black on bill. Other species eliminated via mantle colors and indistinct features. Yellow legged. Primary features are incorrect for lighter mantled LBBG.
