Birds in the Yard

There is a family of birds that live in the school yard.
They make a lot of noise after hours as they scavenge around looking for scraps and insects. They come to the small garden and eat the seeds as fast as I spread them. If any grow, they eat the fresh green growth.
They love the tray of water and are always playing in the water.
They are very tame, and will stand near my foot as I water the garden. They seem to have no fear.
Some children found a little bird that had fallen out of its nest.
They fed it bread and water.
