Here three versions:
From top to bottom I tried to reproduce the suggestions of:
1- Ofnuts (Red);
2- Sallyanne (green);
3- PixLab (Blue).
Krikor, I noticed some problem on your result, did you took the image from Ofnuts' post for your tests?

Yes sure, even better, the process from start to finish on a 50s video

The Pixlab process is creating wider gaps...

True 1 pixel
So you made me re-think, and I found a solution, still similar method, but no more gap
Alpha to selection on the base
Select remove holes
Select Shrink 1 pixel (or more)
new layer ➤ fill
Alpha to selection again on the base
Delete on the new filled layer
Thanks Ofnuts to get me out of my laziness
What I did:
- import the picture in gimp
- made a new white layer
- made a new layer from visible
- fuzzy select the all the white areas from the picture
- bucket fill the section with black
- selection to path
- select none
- stroke path with black brush (2. Hardness 075 / Size 5.00)
- merge path layer layer with the black bird
- done

Another three steps workflow :
1. Colors > Curves...
- select channel Alpha
- inverse the curve : move the bottom left point to the top left and the top right point to the bottom right
2. use Fuzzy Select with these settings
- Mode: add to current selection
- Select transparent areas checked
- Diagonal neighbors checked
- Threshold 255.0
- Select By : Alpha
to select the exterior areas of the subject
3. Edit > Clear

PixLab, I had problems with the image provided by the OP.
Image as seen after fuzzy select a transparent area.
In addition to the lack of uniformity in the background transparency, the contour always presented a pixelation not shown in the other results exposed here on the forum.
So I changed the image before testing the steps.

Click on the OP's image ➤ a new window/tab opens, right click ➤ copy image, then in GIMP 'File ➤ Create ➤ From clipboard` you got the original from the OP which has no defect

By superimposing the final result (the opposite image) over the contours of the initial image, with a red layer in the background, it is possible to see a small gap generated in this process.
At least in my tests, only the procedure suggested by
Denzjos did not present this gap.
denzjos and tmanni, always good to see a different thinking/solution, thanks a lot for your input.
