What a sight to see these birds back again. For a few days I estimated around 50 perched on wires after feeding frenziedly over the crop fields, now it was time to start nest building, and for Swallows that means wet mud.
First they pick up some hay, grass or any other binding material they choose and then gorge on the wet mud to bind it, and when placed to dry the nest becomes a welded mesh of materials. As they gather the mud the long wings and tail almost seem to topple them into the ground before they regain their poise. Every five to ten minutes they would return circling around close then landing for the next mouthful.
