Is it an owl?

IIf you hear it only at night, it is probably an owl. You can't really identify what kind of owl just by the sound, you'd have to catch a glimpse of it. If you hear that sound during daylight hours, too, it could well be a mourning dove.

Here's a link to the City of Boston Nature Center, they might have more info:BPR (Jamaica Pond)

Just watching to see if you find out what it is.

Must be an owl, because it's definitely not a mourning dove. I can recognize mourning doves - one of the few that I know. I'm pleased that it's probably an owl - I find them fascinating

Thanks, Mr Stillwater. I'll try them later this morning.

The owl call typically used in movie sound fx, etc., is typically the Great Horned Owl. It has a deep hoot-like call of three or four syllables. Another common owl is the barred owl; its call is typically 8 or more syllables and sounds like "who cooks for you, who cooks for you-u-u-u" (I learned that in 4-H camp out in the fields of Ohio)
