Feather Quill Knobs in the Dinosaur Velociraptor
Alan H. Turner,1* Peter J. Makovicky,2 Mark A. Norell1
Some nonavian theropod dinosaurs were at least partially covered in feathers or filamentous protofeathers. However, a complete understanding of feather distribution among theropod dinosaurs is limited because feathers are typically preserved only in lagerstätten like that of Solnhofen, Germany or Liaoning, China. Such deposits possess clear taphonomic biases toward small-bodied animals, limiting our knowledge regarding feather presence in larger members of feathered clades. We present direct evidence of feathers in Velociraptor mongoliensis based on the presence of quill knobs on the posterior forearm. This report of secondaries in a larger-bodied, derived, and clearly flightless member of a nonavian theropod clade represented by feathered relatives is a substantial contribution to our knowledge of the evolution of feathers.

Your point is that even half wings had an advantage over non-wings so why did all raptors in that area not have wings? I suppose that there are a number of factors involved including geographical isolation or specific feeding patterns leading to speciation; mating habits and climatological factors.
I think you may be oversimplifying the situation a tiny bit mate and sorry to hear about the Fiji result. Never mind, leave it to us Scots!
