Cape Breton, bald eagles are preying on the nestlings of the double-=20

years, and all of our local d.-cr. cormorants nest there too; I =20
wonder if those eagles are preying on the young cormorants? (and also =20=

nesting gr. blue herons and both gr. black-backed and herring =20
gulls).  Cheers from Jim in Wolfville
