I acquired a Bird Blind two weeks ago. Ordered it from Jason Tan of
Trifid Optical, who imported it from
Thailand.
Only yesterday I have a time for a short test at my backyard.
I placed a ripe mango
(Mangifera indica) on the fence in front of my house, about 15 feet from the hide. Waited in the hide for 15 minutes before this common Yellow-vented Bulbul
(Pycnonotus goaivier) came and tasted the sweet yellow fleshy mesocarp.
The hide is 175 cm tall, can accommodate 1 standing photographer or two sitting persons.
Next the Female Sunbird
(Anthreptes malaccensis) came and pocked its sharp beak through the exocarp.
This is what it look when folded and packed into a circular bag with shoulder strap
. Diameter about 23 inches (60 cm). Camouflage pattern with US Army wording and various logos.

Looking inside in the hide opened door, photographed against the afternoon sun. It get really hot and stuffy sitting there for 30 minutes, without open the zippered windows.
