There is a large bird’s nest on the power pole on the S/E side of Morse between San Pedro and San Marino. Anybody know what bird nests there?

Where can i find accurate schedules for rec center sports (shuffleboard, bocce, etc). I check the Daily Sun listings which say there is no scheduled activity for a particular time only to have groups come up and say they’ve reserved the court and we need to leave. So where do I find accurate listings?
