The nail-makers of Kropa used to catch birds to keep them in their homes. Bird-cages were hung on the walls and some people had up to twenty birds. Then the nail-makers returned home in the evening after a day of hard work which at times lasted sixteen hours the birds delighted them with their songs. In this way they arranged for themselves a little piece of nature at home. They caught males - songbirds - and sometimes took home whole nests including the young. The birds were taught to sing different tunes. Bird-hunting was a passion, but it also expressed admiration and respect of nature around the native place.
