I had a closer, less hurried, look at the 3/3/05 photos on Bob Moul's 
website www.PBase.com/rcm1840 and now see that the bird he photographed had 
a black chin (except possibly for a few small, barely seen white spots) and 
a black throat merging with the black breast band.  This agrees with 
the  rounded wing-tip (the outermost primary [call it P1] being shorter 
than P2 which is shorter than P3)  in indicating the bird is an adult male 
in breeding plumage (the breeding plumage adult female is said to retain 
some white or white flecking on the throat).    Further, the black chin and 
throat of the bird in Bob's photos are similar to those of the bird in June 
Tveekrem photos of 3/4/05 (see also the 3/5/05 posting by Eddie Chapman) 
and suggest the bird Bob photographed is what Ed Boyd termed Lapwing A 
(posting of 3/5/05).  If the lapwing seen from 2/12 to 2/15 (possibly 
2/16), Ed's Lapwing B, is a male - as suggested by the wing shape of the 
flying bird (Mark Hoffman posting  2/14/05) and the comment of Fran 
Saunders (posting  3/6/05) - then the sex(es) of the birds do not help 
decide whether Lapwing A and Lapwing B are the same or different 
individuals.  Until further evidence becomes available, it appears that 
either there are two lapwings present in Frederick County, and both of them 
are males; or there is only a single lapwing and between 2/14/05 and 3/3/05 
it molted appreciably from basic into breeding plumage.
