While taking pictures during a test run, a Hornbill couple stopped on the monkey house roof.
This is not welcome and I can assure you that when the number of birds staying inside is large enough the same couple will visit this BH on a frequent basis.
Main reason being to catch those swiftlet when they come closed to those tweeters.
The hornbill will feed on them or perhaps take home to feed their young one.
I am not very sure what to tell the BH owner to do but ........
The fate of the two black birds will be in the hand of the the BH owner.
I can only give in the pros and cons.
