I recently moved to Central Florida. When I go outside on most nights I hear birds with a very loud call. The sound stops as soon as the sun comes up. It sound like a car alarm. Two calls in quick succession then quiet, then it repeats, sort of like a "Whoo Whoo". The bird seems to travel as I will hear it coming from different locations. I have never been able to see these birds and would love to identify the bird since I have never heard a bird call like this before. Can anybody help??
