Greetings, all.
Having listened to these audio files of Black Oystercatcher, I think that the birds most likely to have been heard at Debert Beach are Semipalmated Plovers. They are very vocal in groups, with descending chortles as heard in these audio files of Oystercatchers. Not quite such high-pitched squeals as the Oystercatchers make, but close enough to be confusing to people who are not specially familiar with shorebird vocalizations.
Cheers,
Susann Myers

Subject: Re: [NatureNS] Re: Possible Black Oystercatchers: Debert
Hi,
Needless to say I was intrigued by this post, as after a number of tries, I was able to finally track down Black Oystercatchers in Klootchman Park, West Vancouver, when I was there a number of years ago. This species is rare even in its normal habitat of rocky shores on the far west coast, and migrates to rocky shores farther south on the far west coast. While nothing is impossible, it seems pretty unlikely that a flock would show up on Debert Beach! Indeed, I'd be surprised if there were any records east of the Rockies. I checked the web site listed here, but couldn't find an audio file to listen to. However, there are audio files on Bird of North America Online (need a subscription), and on the Iphone app Ibird Pro, and I found one here - http://identify.whatbird.com/obj/999/overview/Black_Oystercatcher.aspx , that can be listened to.
To me, if it's a bird, the nearest would be Whimbrel, or possibly a number of different shorebirds.
I suppose another remote possibility would be Eurasian oystercatchers, which have a high pitched short whistle, and I believe there are 1 or 2 records as vagrants for Eastern N.America, or American oystercatchers, of which a few pairs are regular on CSI, and a recent report from Canso.
A mystery indeed!

I thought I'd clarify the situation. The observers, Peter May and Kim Forster, heard something calling at dusk along the Debert Beach at low tide, from the area where the salt marsh grass meets Fundy mud. They didn't see what was calling (though presumed it was a bird), and were not able to make a sound recording. Upon searching the internet for a similar call they settled upon Black Oystercatcher as the bird with the call most similar to what they heard. Here is the web page with the call:

And that is where the mystery rests. They have not heard the call again, but are open to ideas.
Cheers,
Blake
