[cobirds] Re: Parasitic Jaeger- only one previous record from Cherry Creek SP.or Arapahoe County.

Congratulations also to Glenn Walbek for findings this rare bird! Very exacting. I am wondering if this bird is the same jaeger I saw at the Marina Sandspit at Chatfield on the 9th of this month in Douglas County, on week ago. This jaeger I believe to have been a Parasitic and also a juvenile.
