Interesting Mike. Yes, I've also heard Swainson's and Veery give quite a
variety of strongly modulated calls, including a few that seemed to fall under
the context of contact call/flight call. Can't remember hearing that from
Hermit, but it wouldn't surprise me if all Catharus occasionally give
I have heard Hermit Thrush give a call like that, interestingly I have also
heard Gray-cheeked, Swainsons, and Veery give an alternate "flight" call
note. These notes sounds a bit harsher and blurry or jumbled in quality, if
that makes sense. At least Swainson's and Gray-cheeked have more than one
Alll,
This has been a fun thread spun off Jeff's original post. But I have to say,
what really caught my attention from listening to his video clip was that
second call note which has a distinctly burry quality. To my ear, it sounds
very similar to a Rose-breasted Grosbeak. I don't recall
I agree! That thing was a pedagogical masterpiece. I got a bootleg
copy during the World Series of Birding many years ago (likely a
bootleg of a bootleg of a bootleg, actually... I suspect a lot of us
owe you royalties, Bill) and it was the perfect teaching tool. And
even the warts on Side
I think I may still have the original tape, although I don't think I have a
cassette player anymore ;)
Would be great to re-release the original tape in CD format Bill!

Although the CDRom is the way to go for learning and studying, it was Bill's
careful narrative and logic that helped to solidify these calls in your brain.
Look for this ancient medium on eBay.

Hi all,
Interesting thread! My experience with *Catharus*, in general for North,
Central and South America, is that species in this genus regularly use what
people call the flight calls on the ground, during the day, and certainly in
situations outside typical periods of nocturnal migration (of

The Macaulay Library has sonograms for every recording playable online,

I've noticed that in Common Blackbirds Turdus merula, the 'flight call' is also
given in a specific context when a presumed migrant or wintering bird is on the
ground. If my interpretation was correct, these were migrants aware that they

This is a very interesting question indeed. I've spent many years studying
Veery calls. A call will be used in multiple contexts if the accomplishment of
that call is warranted in a give social context. So, a Veery call will be used
in flight and on the ground if the accomplishment (or
they do have short, harmonic, call notes given while perched (at least some
species I am familiar with) -- whether these are ever given in flight I do not
know. And then there is the possibility of elevational or short-distance
migrations or movements in some species. Plus, a number of South
Seems like all the North American *Catharus* do this, no? I'm pretty sure
I've heard Veery doing flight calls on the ground as well. An interesting
question, then, would be whether Central and S. American *Catharus* have
such calls

I wonder if Bill Evans could re-release the "thrush-tape" that Jeff is
referring to on CD (or podcast?) -- that is still probably the best primer for
learning the basic thrushes, and lot of us got started with that tape!

I hesitate to ask this, since I am afraid the answer is obvious, but I will
risk it anyway :)
Is there a (free) online resource that shows spectrograms for all bird species
- not just their night flight calls, but songs, etc.? I've looked around a bit
online but have not found anything
Yes, and remember Bill's classic thrush tape in which he had, if I am
remembering correctly, both Wood Thrush and Bicknell's Thrush singing on the
breeding grounds and interspersing the flight calls in the song? That was such
a great tape!
Last year when I was in northern Quebec I had
17 matches
