Folks:

      Jack Cole asked about Black Rail records in the county.  To the best 
of my knowledge there is only one report in the last three decades away from 
the Palo Alto Baylands--a bird seen at dusk in August at the Sunnyvale WPCP by 
Mike Danzenbaker.  There are a number of "possible" records, but none with 
acceptable descriptions.

      The true status of this bird in winter is difficult to determine because 
of its secretiveness.  A century ago, amateurs used dogs and/or dragged 
chains to survey rails in the marshes and this was an effective technique.  
Where they nest in the North Bay there is some belief that they will respond 
to tapes in winter of the "grr" call.  We've tried those tapes at the Baylands 
in years when we saw good numbers at high tides and had no response.  For such 
a rare bird it is essential to have an excellent look and a complete 
description, but the Catch 22 is that Black Rails do not often provide those 
looks.

      					Bill
