Regarding Great Blue Heron predation on Pied-billed Grebe. I saw a great blue heron pierce and swallow a turtle that was at least 4"-5" across. You could see the turtle going down the herons neck and then the heron let out a groan like I have never heard. I bet it was wishing that it didn't swallow that turtle. ______________________________________________________________________ Ohio-birds mailing list, a service of the Ohio Ornithological Society.
