Also some Limpets put mucus on the rocks that they live in, so that algae which is their food source will grow on it.
And some capuchins use stone hammers and anvils to crack nuts and encased seeds. They keep the nut on the flat stone and crack it using a small pointed stone.
Some Grey herons put bread crumbs to the water as bait to lure the fish and quickly feed on the fishes who get fooled by this method.
Flock feeding technique is shown by birds living in different strata of Sinharaja forest of Sri Lanka. Birds that are at the different strata fly across the forest at the same time. So that the small insects will get dropped off to the ground through the strata. The birds at the other levels will feed on the insects that get dropped down. This technique is adopted by birds living in dense forests and it is an act where different bird species work together.
