Abstract

The 2004 Survey focused on agricultural destruction of nests in large colonies in silage fields. Colonies in silage fields, mainly near dairies in the San Joaquin Valley, usually are lost to harvesting operations (Hamilton et al. 1995). Since harvesting of silage fields occurs in April. the Survey provided an opportunity to estimate the impact of silage colony losses upon the overall Tricolor nesting effort.
