The von Berlepsch nesting-boxes and feeding-stations and baths werein evidence, especially. It is noteworthy that in the most intensively culti-vated forests 80 per cent to 90 per cent of these boxes were occupied; whereas,in the forest at Baden-Baden, where there are a good many old and unsoundtrees, which doubtless offer natural nesting cavities, not more than 25 per centor 30 per cent were said to be occupied.
