Hi folks,
The earlier works of J.C. Saunders (and I recall Manley and Gleich too) might
be helpful resources as well for finding information regarding the perceptual
limit of bird hearing...
I believe that the top perceptual limit for most bird hearing was around 8.5
kHz (from an older Saunders review article). When I was doing a pilot project
(never completed) on high-frequency phase-locking ability of n. magno neurons
in zebra finch (with Sue Volman), I don't recall finding a lot of scientific
evidence of folks actually TESTING this limit in songbirds. Individual species
might have a small number of hair cells/magno cells that can track sound up to
the barn owl limit, I just don't recall people testing frequencies higher than
2.5 kHz. Regardless, it might not be behaviorally relevant even if they do.
Of course, the last time I poked my head in that area was in the late 90's, so
advances might have been made in the interim.

Dear Jean-Francois,
your group of bird species is almost certainly totally deaf at >6 kHz. The
only investigated species that is known to have a hearing range of
(slightly) >10 kHz is the barn owl.
For references, you might like to make use of the publications of Geoff
Manley and Christine Köppl.
