    Equipment Note

NOTES: Early evening honking by a few males (hagadash ibis in background). Some aggressive gasps. Getting to end of lek season (only 20 males vs peak at 92), so calling rate low as well as lower quality (honking) calls. Locations cited on voice track are meter marks along linear lek. Inland vs river indicates on which side of census trail was bat's calling position. Final sequence is male calling with more normal call quality, call rates, and a staccato buzz.
