He heard her gasp as he sprang for the keys that brought the needle gun into play.

It was a precision weapon, a fine, invisible ray of disruptive force. As the first of the web-birds dropped arrow-like into range, the ray touched it. The creature exploded like a fountain of spray. He got two more before the startled birds sheered off.
