Is it or it not that Flycatcher-shrike?

I thought it was good to see this Black-winged Flycatcher-shrike again as I saw it a few months back and has been wanting to sight it again, hoping that it's not just a transit bird.  But on re-examining I might be mistaken because the best images of a bird would be one that leaves no doubt in the mind about its identity.
     Therefore when one gets shots like the following that create doubt, it's most frustrating because it means another chase to track this bird to ascertain its ID.
     These two shots definitely leave much to be desired, having to determine whether these are of the Black-winged or Bar-winged FC.  Ah well, that's a birder's obsession, an ideal shot need not be the most beautiful one, just one that clearly defines the ID of the bird.
