Here's a link to a bit of a mixed bag recording that's got 3 tawny juveniles in, all of them fledged (47 sec, 750 kb):

It's a recording of two tawnies listening to part of a track from the CD
Chouettes et hiboux (Nashvert Production). One of the listening birds is an adult female, the other is a 70-day old fledgling.
In the first half you hear the two fledglings on the cd (reedy squeaks) accompanied by the "live" fledgling, which is making younger-sounding "hissy" squeaks.
The second half begins with the male parent on the cd recording. The "live" adult female chips in with two kewicks followed by a (female-type) hoot. The recording ends with the cd dad and fledglings accompanied by the "live" fledgling.
So a nice variety of the types of juvenile squeaks likely to be heard out there at this time of year. Also a good example of the female's hoot, which is easily distinguished from the male's.

ps: I trust this doesn't infringe copyright as the illustrative excerpt from the cd has been made pretty unusable by the responses of the two "live" owls!
