I saw this happen with a nest that I was monitoring a few years ago, where =
the bald eagle predated the young in an osprey nest to feed it's young. Th=
is occurred in Bridgewater. That is the only time that I was able to witne=
ss this. I've seen interactions between eagles and osprey and after that t=
he osprey harassing the bald eagles on their nest.

Hmm ... some of us have seen eagles attacking gulls.
Wonder if that might have some effect on terns, which are not nearly as com=
mon as a generation or two ago.
Has anyone seen eagle-osprey interactions? I've heard of predation on ospr=
ey nests, but am not sure how common that is.

To your claim that gulls increased in numbers:
My understanding is that they took advantage of open landfills
and also discard of fishing fleets. At least that is the common
understanding of the situation in Europe.
With the closure of open landfills, gull numbers declined.
My remark should not distract from the fact that human
interventions (intentional or unintentional) tend to have
unexpected and/or unintended consequences.

Re: David Webster
[...] This reminds my of the Sea Gull cycle.
The common Gull became threatened in the early 1900's due to
harvesting of eggs for food so egg gathering was forbidden. They
responded gradually and eventually became so abundant that they were
threatening Terns.
A sensible solution would have been to allow Sea Gull egg
harvesting but instead people were hired (or rounded up) to make
distracting noises whenever a male gull was about to get lucky in
areas where Terns also nested.
So one by one, and I would not care to predict what will take the
hit, but logically waterfowl which frequent fresh water/coastal water
will be vulnerable. Perhaps even Sea gulls or Terns.
