I made a quick run out to Jumbo this evening and got better looks at the Jaegers this time. I was able to identify all 3 as adult PARASITIC JAEGERS.
Other highlights included a Common Loon and at least 4 Sabine's Gulls (1 adult, 3 juveniles), probably more.
Jumbo is a busy and exciting place, with birds moving around a lot.
