RFI: Wheatear population in your country (1 Viewer)

Hello to all,
for the introduction of my master's thesis I try to gather the most recent data about breeding Northern Wheatears in Europe (and elsewhere if available). Currently I have found the following numbers and would be very glad if you could point me to more robust, more recent or missing data if available:

Austria 15.000-20.000 pairs (Atlas der Brutvögel Österreichs, 1993)
Germany 4.200-6.500 territories (ADEBAR, 2005-2009)
France 8.000-13.000 pairs (INPN, 2013)
Netherlands 280-320 pairs (vogelbescherming.nl, 2016)
Switzerland 40.000-60.000 pairs (vogelwarte.ch, 2013-2016)
Spain 326.000-361.000 pairs (Purroy 1997, in Atlas de las aves reproductoras de Espana, 2002)

Any help is appreciated

Kind regards
Maffong

Should be figures for the UK in BTO data.....

BTO have several webpages with Wheatear data for different dates (most recent first):
https://app.bto.org/birdtrends/species.jsp?&s=wheat
https://www.bto.org/birdtrends2010/wcrwheat.shtml
https://www.bto.org/birdtrends2007/wcrwheat.shtml
https://www.bto.org/birdtrends2005/wcrwheat.shtml
https://www.bto.org/birdtrends2003/wcrwheat.htm

And also a general info page with some population info:
https://app.bto.org/birdfacts/results/bob11460.htm

FWIW, global estimate is, ah, broad in range:

These guys apparently did at least two European population surveys within the past decade or two:

I'm also seeing a mention of a European population survey by BirdLife International.
This may be helpful:

I'm not finding much about North America. Here's some interesting info about migration routes into North America, but no population numbers attached:
Two geographically separate populations of Northern Wheatears breed in North America. In fall the western population migrates southwestward and the eastern population migrates southeastward, both wintering in Africa with as many as 22 other species of wheatears.
