This patch moves the `gaia/fauna_hawk.xml` template to `birds/buzzard.xml`, because according to the [[ https://wildfiregames.com/forum/index.php?/topic/17389-committed-hawk/&tab=comments#comment-270123 | relevant forum post ]], our hawk is actually a common buzzard (//Buteo buteo//).
Birds do not inherit from `template_gaia.xml`, do not provide any resources, and do not interact, do not even have <Identity>, therefore they don't really belong in the gaia/ folder. A separate birds/ folder makes sense (cf. rubble/, territory_pulls/) and allows for future additions (eagles, falcons, hawks, vultures, etc.).
Apply the patch, then run the following line to adjust all map files:
```
find binaries/data/mods/public/maps/ \( -name '*.js' -o -name '*.json' -o -name '*.xml' \) -print0 | xargs -0 sed -i 's,gaia/fauna_hawk,birds/buzzard,g'
```
