I suspected it was a Rough-skinned Newt and getting my binocs, was concerned to find that it was. I love our newts and our merganser so my concern was for both. I watched for a good 10 minutes as it vigorously mouthed the newt. I had to step away and came back a few minutes later and there was no sign of the merganser, so I didn’t get to see if it succeeded in swallowing. </p><p class="MsoNormal"><o:p> </o:p></p><p class="MsoNormal">I suspected that would be the end of that bird, and for the next two days I didn’t see it on the pond. But on day three, back it was. While we get multiple mergansers sometimes, currently I've been only seeing one, so thought it very probable that it was the same individual. </p><p class="MsoNormal"><o:p> </o:p></p><p class="MsoNormal">Today, the merganser again had a Rough-skinned Newt that it struggled with for a good 15 minutes. Again, I needed to step away, and came back to see the merganser still on the pond, but newtless. I would assume it succeeded in swallowing the newt, but again, didn’t actually get to see it.</p><p class="MsoNormal"><o:p> </o:p></p><p class="MsoNormal">Planning to write Tweeters about this, I decided to google first.
