Optimum width between nesting planks 燕板之间的最佳宽度

What is the best width between planks? This the question frequently raised during plank installation. As we know those planks are installed for the swiftlets to build nest on it, swiftlet behavior and living style should be the first priority of consideration. Install planks closer will increase the plank number with more plank surface area for increasing nesting area, but if the width is too narrow would actually create difficulty in certain extent for swiftlet to fly in.

When swiftlets are to fly in between planks, they will be moving slowly by beating their wings. Total length of their wings is about 7 inches, if we consider two sided nesting in opposite, width should be double as comfortable space. In normal practice, convenience of harvesting also taken into account, I would install planks at about 16 to 18inches (1.5ft) width with some tolerance while not wasting too much of space. In some actual cases, swiftlets are building nest in even 12 inches width, but eggs checking and harvesting work is a bit difficult and slower.

燕板之间最好的宽度是多少？这问题经常在安装燕板被问到。我们知道，这些木板是提供给燕子造窝的，燕子的习性和生活方式就应该是第一优先考虑。如果木板安装靠近些可增加燕板同时增加燕板造窝面积，但是如果宽度太过窄实际上在一定程度上为燕子飞行造成困难。

当燕子在燕板之间飞行时，他们会拍打翅膀慢慢移动，。他们翅膀的总长度大约是7寸，如果我们考虑双对面燕板造窝，舒适的燕板宽度应该是乘二。但在一般燕板按法，同时考虑到收割时的方便，我都安装在大约16至18寸（1.5英尺）的宽度距离，其中加入一些额外宽度且不浪费太多的空间。在一些实际案例，燕子会在甚至12寸宽度之间的燕板造窝，但进行蛋检查和收割工作是有点较困难和缓慢的。
