I have a bird station, food and water bird feeder in my backyard. Under my porch there have always been 2 birds living there in a nest. I noticed they dont have much room there and sometimes when one of them is using the nest, the other is standing next to the nest so I bought a bird house and also a nesting platform which is bigger than the bird house but after weeks I didnt see then using it so I bought a fiber used for bird nest called sterilized natural coconut fiber which has high ratings on amazon but they still dont use either. The bottom part of the bird house and platform are a little over 7 ft high above the ground ( I measured it ) and their nest is probably just 1 feet higher. I wont throw their nest away but I dont know why they dont use the bird house or platform. I bought the bird house so they can sleep in it and during the day they can hang out on the platform. Not sure if picture will be uploaded but already gave sufficient information.
