Re: Have you ever REALLY looked at a bird's nest?

Hi SB:

I saw another great thing on a show called Planet Earth on the Science Channel. They were showing caves today. In Borneo there are huge caves where these small sparrow like birds called Swiftlets build nests on the cave walls. They actually use their saliva to make a thread and build this white half round cup hanging on the wall. Each bird finds its nest with a sonar. Strange thing is that humans take these nests and eat them as a delicacy. There are many companies selling these nests on internet.

I hope you are not bored with my stories.
