Tonight it's 67 degrees and the Martin's are really enjoying the difference from last nights 57. There is a lot of activity and vocalizing. It was however a quiet morning and afternoon as weather was rainy but warm. There may have been a few more SY birds arriving too which might be ramping things up. I expect nest building to start up again in the morning as it is going to be a nice warm day. 

   Martin's activity is very much tied to temperatures, more so than rain which they really don't mind as long as it's not cold.
