Call Identification Help

[Garrett Erickson-Harris]

Could anyone help me identify the bird call from this recording? I recorded it on June 16th, at 11:30 PM. It continued off and on through about 1:15 AM when I went to bed. My initial thought was possibly barred owl fledgling calls, but I am unsure. Today I found a feather which I also believe is a barred owl feather, but again I am not positive. This would back up my earlier belief. I would love to hear any ideas.
