The adult, basic, (light-morph, intermediate-morph depending on your field
guide of preference) Parasitic Jaeger continues to harass gulls at Jackson
Res. A scope or boat are recommended to see this bird. Also, a third
or fourth cycle Lesser Black-backed Gull was seen from a distance.
Speaking of distance, some such photos of the jaeger can be seen at the link
here. Nice find and ID Norm!
