Modern Birdfeeders from Raumhochrosen

These lovely birdfeeders -- replicas of modern houses -- caught our eye, but we don't read German. Our German contact translated (literally) for us:

Lovely friends of architecture, lovely friends of nature.
sometime soon winter is coming,
now, why not think ahead of 'him' and the feathered guests (birds)
who in the upcoming cold season their meals 'enjoy' in well-designed houses?
the grown-up originals are located in vorarlberg (austria, not germany) hand have already many friends of architecture excited.
we are convinced, that the one or the other is seduced by this formidable nature-enjoyment.
