Extending swiftlet feeding hours

Swiftlets are often seen feeding over the fields around the farm in evening hours. Many would continue to feed into fading light. I am doubtful if they could see the insects but could it be they are feeding like whale sharks? Simply feed with mouth wide open. Certainly there are plenty of insects around, seen through head lights whenever I leave after dark.

So I rethink the necessity of attracting insects into a feeding room during the night. Why not just extend their feeding time instead? Good that there is an unused pole to install some lights.



















See the wide open fields - a natural insects breeding ground. How can I do better?





An hour or so extension should be good enough. A timer will take care of that. Lamp replacement is not so easy though! Well, take it as it comes.
