Sooty or Bridled Tern, Australia? (1 Viewer)

Just updating my video library for Bridled Tern with pic 1 from Penguin Island, south of Perth when I noticed my previous example from 28 Feb 2011 as shown in pics 2 and 3. I now wonder if the old bird is Sooty Tern because of apparently broader white on forehead although it does seem to extend just beyond the eye like Bridled. Any thoughts gratefully appreciated.

Bridled is supposed to have paler mantle than read head, Sooty not.

Agreed, but the exposure of image 2 & 3 seems to be making the bird darker than it probably is (note the paler shoulder on image 2).

The white seems to extend behind the eye = Bridled Tern.

Agree, sorry that was not clear
