Could this be the Grey Shrike-thrush?

I wanted to add this video as a post rather than as a video itself simply because I am uncertain if these birds are Grey Shrike-thrushes. I have not heard the Grey Shrike-thrush for some time now, and in fact I stopped listening for the bird altogether. When I was at my neighbour Carol's place yesterday, I began hearing a bird calling that I've heard in the past but not this year. Then a second bird begins making the same calls a lot closer to me.

I managed to get a shot of the closest bird to me to sort of identify the bird species but I can't tell if it actually is a Grey Shrike-thrush or not. The setting sun turned the bird brown, and the shadows from the tree gave the bird a black head at times. But this does not look like the Grey Shrike-thrush that was visiting Carol's garden but the bird's behaviour is similiar to the bird. It is very confusing.

If this bird is a Grey Shrike-thrush, then I am happy to say that this call is another call that that species makes. I did not hear the typical Grey Shrike-thrush sounds that they make either before or after this video was recorded.
