[Dnldhlt@xxxxxxx]

Dear brainy birders,
     I stopped briefly in Kingsport on Netherlands Inn Rd. under I-181 along 
the South Holston River today and saw an American Pipit working the riverbank 
and a yard and driveway.  Does finding them singly on shores like this, 
rather than en masse in agricultural fields, have any correlation to 
migration or other behavior?  Is there anything that would tell one when to 
expect them in one habitat rather than the other?
     Also, several Yellow-rumped Warblers were working the river-edge debris 
and flying over to land on the deck of the restaurant there.  I've noticed 
this particular habitat association before, including a preoccupation with 
manmade structures like decks and old bridge foundations, but I don't 
remember seeing anything written about it.  Is this a real preference or an 
artifact of my selective attention?  If real, do they continue this 
association at other times of year or in other places?
