Two Little Birds Outside My Doorstep

I don't know if this is true or not, but I was told that this is the only species of birds that never builds a nest. They just lay their eggs amoung the branches. It kind of makes sense, since the winds are so high here. Evolution at work.

I also don't know if they mate for life, but they are certainly dedicated towards each other. When the rains come, I always see them huddled together, bearing out the storm.
