The fields here in Northeast Texas used to be full of quail. But,I've lived here for five years since our escape from MA -- and I have not heard a single "bob-white!".
Folks 'round here claim that the $^%#^ fire ants have killed off the young of all ground-nesting birds. (Come to think of it, I have not seen a single meadowlark, either...)
:-(
yup its fireants that did them in
About 10 years ago, I'd sometimes hear that when I parked my car at the office, or when I'd come out in the evening. That was in the north part of Plano, near the golf course that borders on Central/75. That area is all restaurants and a big movie theater now, so I suspect the quail have moved on.
