Thought I'd share this with those of you who have never heard it...
The night that Christ was born a little brown bird shared the stable with the Holy Family. During the night, Joseph built a fire to keep the family warm, but as they slept the fire burned out. From its nest the bird flew down and fanned the embers with its wings. The bird was very close to the fire and the heat turned the bird's feathers red. The breast of the Robin has been red ever since to remind us of its love and compassion for the baby Jesus.
