We have quite a few in Galveston and I have seen large numbers along several highways and throughout the Harris, Galveston, Brazoria, Waller counties. Unfortunately I have seen large swaths or Barn Swallow, Cliff and Cave swallow nests apparently destroyed and washed off by high power hoses in many places.
