Quiet!

It has been very quiet out back! No bird activity at the feeders and only a few sparrows spotted at the back of the yard. I am wondering why it is so quiet. The weather has been good; mild and no rain. The day I had all the activity at the feeder we had a good rain late morning. I am wondering if the weather is the connection to the quiet or did they eat all the "good stuff" from the feeders and have gone to another somewhere? Or perhaps they are coming later in the morning after I have left for work? I will just keep watching and buy some better bird seed!
