Image taken through scope by Tim Hardin. Observed extensively by very experienced birders (Andy Kratter, Tim, and others) both in rest, in flight, and preening.
Identifying features of first cycle LBBG include:
The dark primaries were definitely the nail in the coffin for this ID and were well observed. Unfortunately we could not take any in flight pictures. Huge thanks to all the birders who helped find and ID this bird.
Flying over 441 heading north east. Very large gull with grayish brown uniform coloration. Possibly first cycle juvenile. Pictures added but horrible weather conditions and lighting didn’t make for good pictures.
Remnants of a window collision.
