Pomarine Jaeger, 11/23/11
I spent 5 hours in my boat with Paul Conover looking for jaegers off the Cameron coast on Nov 23, 2011. This adult Pomarine Jaeger was jumped from the water as we were running about 2 miles out from shore and 2 miles east of the Calcasieu Jetties. We were able to run with it and get ahead of it several times. This allowed us to get photographs as it passed overhead.

Pomarine Jaeger, 11/23/11, Belly Patch
This was taken after we again got ahead of it. The dark area in the flank developed after a skermish with a gull and taking of it's fish. It should disappear after preening. The dark area on the lower belly is a permanent coloration. I have photographed only one other jaeger with a patch exactly like this. It was on December 23, 2010, at the mouth of the Calcasieu River Jetties. All of the other colorations match that bird as well.

This is a photograph of the jaeger with the same markings taken on December 23, 2010. The location of the two photos were about 2 miles apart off the Cameron coast.

Comparison of 2010 and 2011 photographs
This shows a comparison of the jaeger photos eleven months apart. If it is the same bird, it would have undergone considerable molt. Because it is an adult, perhaps the color pattern remains the same. The belly patch is so unique to the other jaegers I have photographed, I am inclined to believe it is the same bird.
Because we have so many adult Pomarine Jaegers off the Cameron coast, I have felt that some may return for at least some of the winter each year. This is the first one that has a close enough color pattern to encourage that idea.

The following photographs are of other adult jaegers taken off the Cameron Coast out from the Calcasieu River. They illustrate the variety of patterns possible. None of them combine features to match each other or the above jaeger.
