视觉记录 Visual Recording

我打理好几间新旧燕屋，一些是自己一些是合伙的，我对管理工作的一部分就是记录数据以监测燕屋的成长健康性。或者是在修改或升级燕屋的情况下，我们怎么知道是否理想？有些人可能会数燕窝数目或鸟粪堆的数目，但对于那些已有不少窝的旧燕屋可能不太实用，因为这很耗时。其中一个方法是记录燕窝收割的重量。此外，我也习惯用照像拍摄来作记录尤其是燕群角落，这可以是一个对燕屋管理很好的记录和日后参考。

I am taking care of quite a few BHs both new and old, some own and some JV, part of management job for me is recording data to monitor the growth. Or in the event of revamping or upgrading of BH, how do we know whether we have done a good job? Some may count the nest numbers or bird dropping spot, but for those old BH with lot of nest might not be practical as it will take long. One of the ways is taking weight of nest harvested. Besides, I am used to practice visual recording such as photo shoot especially on populated corner, which could be a good recording and reference for your management.
