Just my thoughts on your unknown….
Unknown1 definitely sounds like and oriole, but I couldn’t say that a Baltimore
wouldn’t sound like that. Your unknown 2 sounds good for American Bittern to me.
thanks for posting your lists and unknowns as a way to get more of us out there

Lots of recent activity here in western Pennsylvania, including a few calls
that I wouldn’t mind second opinions on.
First is the attached call labeled “Unknown1” which sounds to my ear quite like
the “yeehr” of an Orchard Oriole, but this species (according to the Evans and
O’Brien CD) is not known to call on nocturnal migration. Is there something
else this call could be? I will say this isn’t the only time I’ve heard this
type of call over my yard but this is by far the best recording I’ve gotten of
a call of this type. (May 2 at 12:31am)
Second (Unknown2) is another low-frequency call like the possible Least Bittern
I posted last week. This one sounds like a Black-crowned Night-Heron to me …
any other ideas? (May 2 at 1:43am)
Lastly is the call I listed as Cedar Waxwing on this eBird checklist:
http://ebird.org/ebird/view/checklist?subID=S29290856. This would be the first
nocturnal Cedar Waxwing call I’ve had here, and was wondering if this really is
definitive or if there are any other possibilities for this call. It seems
pretty spot on for waxwing and apparently they are known to call at night
occasionally, but I always like to be cautious with “presumed” birds like these.
Of general interest, the biggest night of the year here so far was May 1-2,
which was interrupted by a thunderstorm that came along around 3:45am. Here is
the post-midnight checklist with several clips:
http://ebird.org/ebird/view/checklist?subID=S29412937. Both of the attached
Unknowns were made on this same night, by the way.
On May 3 I was surprised to hear a Greater Yellowlegs song on the recordings:
As always if there are any errors in any of these checklists please let me know.
