Yep, simple spectrogram cross-correlations can work surprisingly well 
(sometimes much better than certain sophisticated patented digital signal 
processing algorithms...). In Avisoft, this kind of correlation is available in 
the separate CORRELATOR application or in SASLab Pro in the commands 
"Analyze"/"Specials"/"Detect and classify waveform events..." or 
"Analyze"/"Specials"/"Scan for template spectrogram patterns..."
