A mixed feeding flock.
Sacred Ibis, Eurasian Spoonbill, African Spoonbill, Little Egret, Intermediate Egret, Great White Egret, Black Egret, Western Reef Heron, Pink-backed Pelican, Great White Pelican, Yellow-billed Stork. There were also a few Striated Herons & Long-tailed Cormorants on the distant bund.

The Black Egrets like to keep pace with the Yellow-billed Storks. Presumably the storks disturb small fish which then seek shelter under the Black Egret's "parasol" only then to be picked off.
