I finally found a post office in my area that actually has a stock of these stamps. For anyone so interested, here's a scan of the five stamps highlighting the location of the "USPS" microprinting incorporated in each stamp:

Now for a question: These represent a horizontal strip of 5 different stamps, with the sheetlet containing 4 rows (20 stamps total). Each "strip" starts with a different bird:
Row 1 starts with Northern Goshawk
Row 2 starts with Golden Eagle
Row 3 starts with Northern Harrier
Row 4 starts with Peregrine Falcon
No strip of 5 starts with the Osprey.
If one chooses to collect only a strip of 5 for album mounting purposes, which is the correct sequence to collect -- or does it matter?
