Jaegers

[pdx_bird]

Hi all, I'm having some trouble identifying these jaegers. Is anyone good at that?

Seen on a pelagic trip off the coast of Oregon last week. 

1. B&W barring underneath, pale belly, gonydeal angle near midpoint (?) - Long-tailed Jaeger?

2. Blocky squarish head, long bill in relation to head makes me think Pomarine, but the uniform underwing makes me think Long-tailed.

3. Gonydeal angle near tip, light belly, gray brown vent - Parasitic?

 

Link to all the photos if that's helpful here.

Bump.

I've answered my own question by emailing one of the guides on the boat. 

Here's the response: 

#1 and #2 "The best field mark is the upper wing view.  See the white primary shafts on only the two outer primaries?  Diagnostic for LONG-TAILED. Thin bill also good, as is mouse brown back color." 

#3 "First, eliminate the one you easily can. Wing flash? Yes. That alone eliminates Long-tailed. Sharp longish tail eliminates Pomarine.  PARASITIC."

 

I was on the right track though missing some key characteristics. Very helpful tips!

Nice job! I agree with him.
