Manifests intense male excitement, as in territorial defense or association with responsive females. Often given following chases or aerial duets, also by migrants and residents outside their territories" I had read that but I cannot discern the 'several whistles' in my recordings that BNA states is normally given at the beginning. And since BNA didn't say anything about those very distinctive flute sounds (plus my bird wasn't flying), I didn't recognize the BNA account as descriptive of what I was hearing. Though I didn't observe my meadowlark chase other birds off (as Scott noted about this vocalization being associated with chases, and BNA describes), it clearly could have just returned from a chase when I drove by and heard it singing.
