"I think I found the right video for a match: https://youtu.be/-oSNzxN3kfo
Spring Peeper it is, case closed :)
Thank you very much for figuring this out (my mom and dad will be glad to finally know what it is)."
"Thanks, Ryan. Spring Peeper is the best answer to your query as most birds do not call both day and night.
BTW, I did not suggest Cardinal... one of the many different focuses of that video from YouTube was of a Cardinal."
"I had never thought of a cardinal. I had tried listening to call samples, but it's pitch seems off from the mystery bird. The suggestion or the spring peeper is very good as well, the sound is very close, but the only difference we have is…"
"I've heard this same call frequently in the woods behind my place as well. It most often calls in the late evening until well after the sun has gone down. Drives me crazy not knowing what it is. :) Hopefully someone can figure it out. "
"I suggest you check the call of Tufted Titmouse..... I'm not saying it is your mystery bird but is one that does the Peter, peter, peter call. They have nested in NB. It does not visit feeders until cold weather arrives.
It would be interesting…"
https://youtu.be/Qjw8IqI6iBYMy parents live in Southern New Brunswick and have heard this bird all Summer at all times of the day and night. Unfortunately, it has never come out of the forest for them to snap a picture of it. I was able to capture the sounds it makes the other night and posted it to YouTube. My folks and I would really appreciate any help with putting this mystery to rest.See More
