Determine noise per hour

After making a recording of some parrots, I want to determine how often they make a sound. I need something that determines the start and end of a sound and count that as one. Then is just a matter of exporting the time of that sound. With that I could easily plot the data in excel.

Any ideas? Anyone that can develop this for a fee?

Thank you

As Koz said ( ) it may be best to produce an audio file that is the sum total of the squawking, so continuous over that time.

If there is enough difference in loudness between background noise and the squawking, try Analyze > Sound Finder.
