In February of 1993, my wife and I witnessed a Bald Eagle take a large
gull (Ring-billed?) by flipping over at just the right moment at
Beverly Beach just north of Newport, OR. The eagle dropped into the
water with the gull in it's talons, and we wondered to each other if
it was drowning the gull. There didn't appear to be much struggle
from the harasser-turned-victim, and after a few minutes, the eagle
struggled back into the air with the gull and flew off towards Otter
Rock and Cape Foulweather (north). In the fall of 1993 we returned to
Newport, on another vacation, and saw a family group (?) of two adults
and an immature along that same stretch of beach, and wondered if that
eaglet, now fledged, had had seagull for lunch one day.
