When you wanted to built a BH closed to the sea front you will need to be very careful with the high wind during monsoon season.
What will be your best options?
High wind during monsoon seasons will in general effect your birds population. In some cases you will experience missing birds during those high wind period.
There are many reasons and let me touch on a few:
1) Once the wind velocity are too high their food sources will become scares. This is due to the fact that the insect will have difficulties to fly around to find food.
2) High wind can also cause the birds to use more energy during the flight, especially going against the wind direction. If they use more energy then what they generated from those scares food they will not be able to survive. They tend to migrate, temporarily, to those areas where the wind are not that ferocious
3) If your BH design is without any consideration of high wind, you will find that the birds will have difficulties to enter the BH entrance hole. They might hit the side walls and injured themselves.
4) High wind entering your BH will in principle create a poor conditions in your BH. Once you cannot control the outside wind entering, the temperature and humidity will be similar to the outside. It that happen the birds will not breed thus there will be no nests to be build.
5) If there are babies during this high wind period there is a very strong chances that these babies will die. High wind that enter your BH will actually kill those young babies.
6) Monsoon season will not only bring high velocity wind but also rain. If you BH land is too low you might face flooding problem. Yes in the air high wind and on the ground too much water.
What will be your best options?
Try to move your BH as far away from the beach front as possible.
If you have extra land near to the sea, you might consider planting those trees that can block or divert the high velocity wind away from your BH entrance hole.
Some people build a kind of wind deflector, something like advertising board, to minimise the wind velocity especially at the entrance hole.
There is this special veranda designed that I saw in Pontianak. The entrance hole is covered with a 4-6 feet veranda to minimise the air velocity.
In Sibu, Sarawak, the owner built his BH on a 2 feet stilt to minimise those flooding water if it happened to occur.
You might need to consider designing a flexible entrance hole size. If possible have a roller type where you can open and close the entrance hole to the size that you can adjust. During high wind you might want to reduce the hole size to the minimum while on normal season you open wide.
