Cant offer any opinion on the bats cos' I think we aim to create a cave environment. Once we get that, bats like it too. I think in the natural environment, bats & swiftlets share caves. Would like to listen to sifus' opinion.
It was shared in an earlier post (if recollection doesnt fail me) of a similar experience.
Just cant remember if a solution was offered then in the post.
My inference is that echolation is used only selectively (same way you use yr high beam for night driving).
This is borne out by the fact that when you see them in flight, you do not hear the clacking sound all the time.
Me thinks that birds at the point of going in dont use echolation (same way, you dont check for obstacles when you enter yr own room).
IMHO they fly in thru habit/conditioning and then turn on their ecolation in the dark to get to their own nest.
If it was my bird house, I will remove it immediately, and if need be, will install the partition incrementally ie maybe 3 inches at a time.
My 2 bits.
Hi Cergau,
Yes agree with you. Swiftlets do not use ecol-location all the times. I can hear the clicking sound when they are in dark area especially when in the birdhouse locating their favourite nesting places. They are like us human beings too, being over confidence in familiar areas. Hope they can adjust soon and do not abandon their nesting area just because of some obstructions along the way.
As to your new design birdhouse, I am no expert but with the experience I encounter for my birdhouse, I think the roof entrance is good. This is because this design will cut out the lights unlike mine dog kennel type and it is too bright, that's why I have to fit extra "wall" to cut out the glare. I feel your ceiling is too high when come to harvesting the nests. Initially when the nests are few, it is not too bad. But imagine once there are full of nests.....just imagine how tough it will be. I have seen some as low as 7' only, yet there are full of birds.
Just my 2 cents to share.

Just to share what I believe
1.How high should it be......obviously, the higher the better as there will be no obstruction to the bird and if your floor is high, you can even be there and the birds will not care nor concern about your present in the BH but then....beware, the higher it is, the more dangerous it is for you. The Better for the birds, but the worst for you. Most accidents happened in BH are caused by falling off ladders and many have broken arm to tell tales. Simple thing like climbing ladder will be problematic when you are tired like having climbing up and down harvesting hundreds of nests and you may just slip and fall to the ground.
As for the holes in the BH for the birds to go down to the lower floors and again, caution as the holes may be your way to heaven as as you are working in a BH where lighting and congestion plus the unpleasant of wearing a mask will disorientate you and cause you to fall down. Best if you can have blocker around the holes although it may alittle obstruct the flight of the birds but it wil save your life. Remember the case of a BH owner (a Millionaire before venturing into the BH Buz) fell to his death in his BH thru a hole in the upper floor of his BH.
Doing a new BH, you must consider from both angles, the birds and you in particular.......not use of a successful BH if you are dead.
Most of the designs that I have seem are typical types and most of them are similar. You see one, you have seen most of them all but to me, many can have better designs for the birds if you are doing it in the plantation cos there are no building specifications to follow............obvoiusly, there are always risk to be the pioneer in designing new designs.
Don't ask me what I have in mind cos I won't be telling as I reserve it for myself.........my dream BH.
As always, above are my opinions on the matter and all may comments and happy to hear if I am wrong.
