   • 1969, American Aviation, volume 32:

5. The American night heron.
6. (programming, informal) A warning message indicating a possible error.
   • 2012, Scott Meyers, Effective C++ Digital Collection: 140 Ways to Improve Your Programming:

     The function-hiding code above, for instance, goes through a different (but widely used) compiler with nary a squawk.
