What Kind of Entrance Hole You Should Opt If Those Birds Are Coming From All Over?

While in Pontianak, Indonesia, I was asked on how to choose the right type of entrance hole for a newly built BH.

The question came from a guy who already have a BH at the same location where he is building a new BHs.

Luckily I was there one whole evening observing where those birds are coming from.

I sat there for almost 1 hour from 5.30 till darkness.

At first I was given the impression that those birds comes from only two directions. However after one hour observations, plus lots of mosquito bitting my legs, it seem that they were flying home from all directions.

If that is the case, for your BH, you should go for an open roof concept where you can allow those birds to fly in from which ever directions they are coming home from.

Will this apply to a cross flight path? Yes it is. If those birds are coming from more then one directions, the best is the open roof type.

If they are coming home only on one single path then it is okay to go with a side window and let the window face the coming hole direction.

The sound tweeter should be placed at an angle such that you can pull those birds towards your entrance hole.

Disclaimer: The above recommendations are valid if your BH is located on an agricultural land and not in a shop houses. For a shop house location, you need to do more then the flight path observations but in most cases roof top entrance can cut down lots of sound.
