Well, it is amazing that owls literally speak to one another and communicate. What really surprising is that, when a pair of owls make their duet hoots and talk to each other...... My typical example from my location here in Africa, Ethiopia is the dueting of the African Wood Owl (Strix woodfordii).

So many surprises, the raccoons, white-tailed deer, and gray fox were really fascinating. You can definitely tell sounds coming from larger owls vis medium to smaller owls. I've been lucky enough to hear barred, e. screech, and great-horned plenty of times. I also heard shorties vocalizing during a recent encounter at dusk. I'd love to hear a saw-whet though.

White tail deer! I hear Great Horned Owls but now I realize I may be hearing other species, time to pay closer attention. This was an interesting presentation.

wow!!  that was a humbling exercise ! Amazing  diversit of sounds .

The Fox and the deer sounds were surprising to me.  We have lots of deer in our woods and I have never heard them make that sound. I have heard the Barred Owls caterwauling to each other before.  I was surprised by the Racoon calls.  I have heard the Barn Owls screaming at night before.  Also, the Great Horned Owl.

I found it interesting how many other animal or bird sounds could be mistaken for owl sounds. When I was a kid, I always thought dove sounds were owl like. It just shows how sound identification of a bird, especially owls, can be a challenge as you get started. Of the owl sounds, I think that of the Great Horned Owl is what I have heard in person in my area, where as for the Barn Owls I have heard them on nest live cams.

The fox! What does a fox say?! 🤣

Based on this, I have heard many creatures in the night which I had not expected. The particularly spooky call of the grey fox and deer were a surprise. I have heard Barred Owls, Great Horned Owls, and Burrowing Owls either in my area or back east. I will try to have Merlin on-hand for any future calls I hear in the night, which could possibly be Owls or other night-time birds.

I found them all very interesting and a little surprising. I guess the common gray fox may have been the most surprising. Is there a good place for non-bird animal sounds? I've heard a few that neither I nor Merlin have been able to identify and sometimes I wish I had a better knowledge of non-bird sounds. Nik

I was really surprised by the deer sounds!

let's just say there are no standard rules of thumb

This was fun and interesting. The thing that surprised me the most was the gray fox!

Does one owl species understand the sounds of another owl species? In other words, when a barn owl produces a sound stating "this is my territory," does a barred owl (or any other owl species) interpret the sound in that way?

This was so interesting. The little gray fox was absolutely wild to hear. When I first heard the noises Cougars made, I was similarly shocked. Nature is so wonderful. I’m not very musically gifted and it’s always very impressive when someone is able to identify birds and other animals by their sound. Well done!

Common Gray Fox (so scared)

The Mourning Dove definitely sounded owl-like to me. In my area, the calls of the Barred Owl and Eurasian Collared-Dove are often confused.  Both are relatively recent arrivals in the region.

The first time I heard Barred Owl duetting was on a float trip on the Eleven Point River in the Missouri Ozarks. We were camped in the woods along the river, sitting around a campfire when the "hootenanny" started up. Really a memorable experience!

I would like to say that I think that it is so fascinating that there are so many sounds out there at night that we need to hear and pay close attention to at night.  The owl calls are literally fascinating especially the recording of the duet

The grey fox sounded like a screaming woman. We have barred owls and great horned owls.

I have been around white-tailed deer my entire life. I had no idea they made vocalizations like those presented here! Wow. Same with raccoons...I have never had the pleasure of hearing them call. I have heard owls at night. I just returned from Shenandoah National Park and heard owls at night. But have no idea which of the many species located in the park were doing the calling.

I was most surprised by the deer! I know fawns bleat and the adults will huff when threatened. But, I'd never heard something like that before.

The sound that surprised me the most was the Bush baby. It definitely sounds like an owl. Where I live, the sounds I hear from an actual owl at night is the barred owl. I was outsidedoing this course and heard it. There is one for sure pretty close to my apartment. The other sounds I hear are bats, frogs, and a group of coyotes. They were really close and loud last night.

Me sorprendió más el canto a dúo de Atrix varia, no sabía que en los strigiformes podría encontrar algo así al igual que algunos paseriformes de mi país como el Furnarius rufus.

the fox!
