Do they no longer share this enclosure with Cape Ground Squirrels? ZTL still lists them which seems to be fairly up-to-date for Magdeburg (updating things before the zoo has announced them), so I presume they have moved elsewhere in the zoo?
Interesting, a shame if both they and the Bateleur Eagles in this house have gone - both were lifeticks for myself and made for a really lively feel to the building.
