On July 5, 2003, the landlord of a 1 pair Purple
Martin colony site near Portersville, PA saw 2 subadult male martins
investigating his site. He used a Swarovski spotting scope to read the 4
digit alpha-numeric codes on the martins' yellow color bands. One was
Yellow A485, banded in 2002 as nestling at a colony site in Grove City, PA.
The other was Yellow P108, banded as a nestling in 2002 at a colony site in
McKeesport, PA. On July 10, while I was doing some routine band reading at
my colony site in Sarver, PA, with my own spotting scope, I saw the same two
SY-M's. They were apparently non-breeders traveling together and were now 27.0 miles
southeast of the colony site that they had been spotted at 5 days earlier.
