How can I keep a moving subject when stitching a panorama in Photoshop?

I’m stitching several overlapping photos into a panorama in Photoshop. One frame includes a fast-moving subject (birds) that I want to keep, but Auto-Blend replaces that area with content from another overlapping image.
I first tried editing the layer masks after Photoshop stitched the panorama, but that caused visible seams because the tone/blending adjustments no longer matched.
What’s the best way to preserve a specific subject from one frame while still getting smooth panorama blending?

I finally found a solution which is embarrassingly easy, but it has not occurred to me before.
Perform the auto-align and auto-blend steps separately. After the auto-align step, simply wield the eraser tools and delete the offending parts of the layer that could cover important content. Finally, execute the auto-blend command.

A practical way is to separate the panorama process into two steps:
- Auto-Align first to line up all the frames.
- Before blending, remove the overlapping parts from the layer(s) that would cover your desired subject—for example, erase or mask out the area that competes with the birds.
- Then run Auto-Blend Layers.
Why this works: if you edit masks only after Auto-Blend, Photoshop has already calculated its seam placement and tonal blending, so revealing extra areas can create harsh transitions. By excluding the unwanted overlap before Auto-Blend, Photoshop builds the blend around the subject you want to keep and can still smooth the transitions in the remaining overlap areas.
Using a layer mask instead of the Eraser tool is safer because it’s non-destructive, but the key idea is the same: align first, trim the conflicting overlap, blend second.
