Well designed graphical representations of bird calls would be very useful, after the association has been made between audio and graphical features. Graphics can be examined out of time, as it were: there is no need to replay them in a loop, many can be compared at a glance, particular details can be examined carefully without distraction by the rest, etc. There is a reason people make graphical displays of many types of information: the visual system is a low latency, high bandwidth, high sensitivity, very effective pattern matching tool. Among other things this is why we read instead of only listening to spoken language, and why we write music using graphical notation.
