Going deaf on the Fraser, 17 Nov2016

Eagles on a snag in the estuary of British Columbia's biggest industrial river, an international airport and sea plane terminal off screen right. Hear the din from - jetliner turbofans, sea plane piston engines, occasional hovercraft and motorboats. Lady dining on salmon at left, mate patiently waits for her to finish. At 22:20 minutes they seem to attempt reply to a distant eagle's call. Or scream objection to the engine noise?
