The addresses for Bob Moul's web site I listed in my earlier email 
erroneously contained an extra "l".  I am resending the message with the 
addresses corrected.

>gallery at www.PBase.com/rcm1840 displays the same pictures.  These photos 
>show that the outermost primary is clearly shorter than the next primary 
>(moving inward) and that the wing has broad bulging primaries.  If the

>in Bob's photos was a male.  Because he took them on March 3 and the bird 
>clearly has a white throat it is the one Ed Boyd called Lapwing B, the one 
>photographed in flight by Mark Hoffman.  So, if someone can get a photo of
