Media notes
NOTES: DRAINED SWAMPLAND CONVERTED TO PASTURE. CLUMPS OF ORIGINAL FOREST REMAINING. ALTHOUGH I DID NOT ACTUALLY SEE THESE TYRANNUS MOBBING A BUTEO MAGNIROSTRIS THERE WAS MUCH TO SUPPORT THE HYPOTHESIS. ONLY ONE SCREAM FROM THE HAWK IS HEARD ON THE TA Age: 25 UNKNOWN AGEPE. THE BIRD WAS SEEN LATER. THE TYRANNUS IN THE VICINITY OF THE HAWK WERE CALLING EXCITEDLY. TWO BANDS OF 4-5 EACH FLEW OVER TOWARDS THE EXCITEMENT. OTHER BANDS JOINED FROM OTHER DIRECTIONS BECAUSE THE RACKET GREW IN VOLUME FOR SOME TIME. THEN THE EXCIT BNA: I do not know what category to put these vocalizations in. mf.
