If I am correct, the movie I saw was shot by Alexandre Promio, one of the earliest of the Lumieres' acolytes. He traveled around the world, to Britain, Canada and the US, and seems to have spent some time at the London Zoological Gardens, shooting (with a film camera, not a gun) lions, and here, pelicans, flapping around their enclosure. There are a couple of onlookers.
The copy I saw seemed to be damaged, with the movement slow and erratic. Apparently Promio was still learning to crank his camera; within a couple of years, the ability to crank at a steady place, varying the rate at will, would be a prime ability. It wouldn't be until 1912 that a motorized movie camera would become commercially available.
