Hi Fleur,
That is really interesting! Any chance you could write it up for publication in Biodiversity Observations (which was created to allow sightings such as this to be published and available for reference worldwide)??

Greetings birders
On the museum grounds today, Nature Kenya's Wednesday Morning Birdwalk was
treated to a battle over a nest high in a big eucalyptus.
Originally built by Great Sparrowhawks, the nest has already been used by
Lanner Falcons as well as Great Sparrowhawks. Today four species were
claiming the site: Egyptian Geese, Lanner Falcon, Great Sparrowhawk and
Black Kites. The geese actually stood on the nest for a while, but when the
birdwalk ended it was the Great Sparrowhawk that was still in the tree.
Wishing you good birding, Fleur
