It's hard to put into words the 'feeling' of a place like Auschwitz but moose could have a point about 'mental' blockage, even if you're normally aware as a birder of birdlife around you when you visit various places. On entering the Camp, the first thing visitors do is enter the 'museum/lecture' room and watch a horrific realtime b&w documentary of what went on there. Up to entering, I'd been scanning skies/horizons for raptors etc and was pretty keyed up, but then it's like a complete paradigm shift in perception - birds become the last thing you are aware of other than the very strong realisation that none are singing as you start to walk to the 'huts' and the confirmation that the old adage is true. The gas chambers are also the first building visible from the car park. Bizarrely, there's no reason why there shouldn't be a good population of birds there, the Camp itself has many surrounding trees and the gas chambers are set against a backdrop of healthy woodland. The great wrought iron writing carved into the overhead entrance arch: 'Arbeit macht Frei' (sp?) stops you in your tracks though and the idea of birdwatching not only dissipates completely but belongs to another era - from then on, it's piles of shoes and false teeth and weeping Jewish pilgrims that dominates the conscience. Perhaps a return visit, with the primary objective of focussing on birds and an effort to deliberately 'de-sensitise' yourself with your surroundings may prove birds dwell 'happily' there, abeit silently!
