Catbird

 Often in the nesting season this trim bird is a close neighbor of man.  Like the mocking bird, the Gray Catbird is regarded as a mimic, but it is less an actual imitator than a plagiarist of musical ideas.

The catbird suggests the songs of various birds -- never delivering them exactly as heard.  It burbles along, now loud, now soft, uttering a long run of squeaky phrases, seldom repeating itself.  It gets its name from its call note -- a petulant, catlike mew.
