Never thought that they can come in great numbers.
I was on my way back to Kuala Lumpur and stop to see the BH activities from the outside.
The weather on the day was fined a bit drizzling.
The wet condition must have make those birds to be easily lured to those external sounds.
Marvelous and very exciting to see such a nice activities around the monkey house.
I know some will enter the monkey house and perhaps some will move into the nesting rooms.
You never know until your next visit.
I am not asking all to be my tenants but just a few 10-20 % will do.
