That usually means that wind blown rain has gotten the nest all soggy. That is why if you ever have an abandoned nest, it is a good idea to save it in a ziploc bag. Sometimes in a pinch, you need a replacement for a soggy nest or one that is full of blowflies.

Interesting, never thought of that but never got a chance to get fully up and running over here either. That I will definitely keep in the back of my mind.
