They insist on building their nest every year in a hole in the pipe next to our cellar.
I've tried convincing them that it gets too hot in that pipe. I have yet to see a live baby bird emerge.
When we left for Alaska, their were five eggs in the nest. Neal checked in on them when we returned, and only found one. By the next afternoon, it too was missing. (I haven't seen our "king" lately, but I was suspicious.)
A few days later, another egg had appeared. The next day--two. And now, once again, we have FIVE eggs in the nest.
