Re: [nfc-l] Catharus thrushes in weird places
Hello Olivier, I accept that to more experienced NA ears the Swiss call does not sit comfortably with Swainson’s Thrush. Bill Evans told me it ends at a frequency that would make it atypical for the species, and some clear modulation would also be desirable. However, the Chaffinch call you are referring to is not a flight call but a breeding season call used in a songlike manner. I’ve never heard it after the summer. The two flight calls of Chaffinch are a low, soft, rapidly descending ‘puw’ and a loud, bright ‘pink’, especially when flying alone. I also hear finches at night now and then, but of the genus Fringilla i’ve heard Brambling a few times and almost never Chaffinch despite Brambling being much less common. Other night finches here include European Goldfinch and, this year in particular, Hawfinch.

Re: [nfc-l] Catharus thrushes in weird places
Magnus, The Swiss recording does not sound like a Swainson's Thrush to me, other than superficially. The spectrographic signature of this call doesn't look right, either. Could this simply be a Chaffinch? Its quite low-pitched, and there seems to be a bit of echo. I rarely hear finches at night in North America--they are for the most part diurnal migrants, like Chaffinch--but it happens.

[nfc-l] Catharus thrushes in weird places
I like the idea of a detector for Catharus thrushes on Scilly! But there are two places perhaps better qualified than that. This year saw three records in Cork, southwest Ireland and just one on Scilly. But the ‘European’ capital for North American vagrants is now Corvo in the Azores (actually it’s on the North American side of the mid-Atlantic ridge!). Have a look at this list of what was found there this autumn. http://birdingcorvo2013.blogspot.pt Talking of Catharus thrushes in unexpected places, I’d be interested to know what North Americans make of this. I was surfing around on Xeno-canto the other day and I came across this mystery NFC recorded by Thomas Lüthi (CC) in his garden in Switzerland in September 2015. To me it sounds like a Swainson’s Thrush, and I can’t think of anything European that comes this close. How does it sound to people with real experience of this species? I only know the NFC of Swainson’s from recordings. http://www.xeno-canto.org/386520 all the best, Magnus Robb > On 09 Nov 2017, at 00:08:26, Ted Floyd wrote: > > Sure looks (and sounds) like it to me.
