All of these jaegers were photographed along WIsconsin Point, Superior WI in August-September 2013. It has been an amazing fall for jaegers, with five Parasitics showing up on the early date of 13 August, and I have been able to see multiple jaegers every subsequent trip through 27 September. By comparing photos, I have been able to determine that at least 22 Parasitic Jaegers have been seen: 5 light adults, 12 light third-cycles, 1 dark third-cycle, 1 light second-cycle, 1 light juvenile, and 2 intermediate juveniles. The many third-cycle birds were aged based on the combination of adult-like head and underparts but with some white mottling/barring in the underwing coverts. Some of these individuals have stayed here for over a month! (the longest staying bird, nicknamed "notch" because of its broken P7 on the right wing, was here for 45 days from 13 August-26 September!) Interestingly, third-cycle #1 ("notch") dramatically changed its appearance from 13 August to 14 September, acquiring extensive basic plumage barring on the underparts which at first glance made me think it was a different individual, but the notched P7 and the pattern of barring in the underwing coverts are identical. An amazing four different Long-tailed Jaegers were also identified (2 adults, 1 third-cycle, and 1 dark juvenile). My thanks to Peder Svingen, Mike Hendrickson and Ted Keyel for their help in sharing photos and adding dates and individuals to this database as noted. Here are the individuals I have been able to identify and the dates seen:
