Historic Upland Sandpiper Breeding Surveys from Vermont, USA (1989-2001)

Increases in adult numbers and the number of nesting sites during this period were documented; however, these increases were attributed to refinement of survey techniques as opposed to actual population increases. Highest counts during this period were 126 individuals located at 47 sites with a suspected stable population of 80-100 pairs. Another set of surveys was conducted in 1998 and 1999.

The 1998 survey showed a 60% decline in numbers (50 individuals at 22 sites). The 1999 survey showed a decline of 78% with only 28 individuals at 15 sites. Subsequent, but more limited, surveys in 2000-2002 showed findings similar to 1999.
