Searching for Weavers.2

We would pull into the large pond formed by the Sunset Dam each day.  There we saw a variety of shorebirds and hippos keeping cool in the water.  In the middle of the pond was a large, dead tree that was covered by the nests created by a group of Lesser Masked Weavers.  An African Harrier-Hawk knew those weavers were hiding in their nests so it tried to flush them out by landing repeatedly right on the nests.  I never saw one weaver try to sneak out so the Harrier-Hawk got increasingly frustrated.
