Foraging Ecology of Fall Migrating Shorebirds in the Illinois River Valley

Grant/Contract No: 301817G038 Mod. # 1As of mid-November 2008, we have: 1) removed, and preserved the ingesta of 134 shorebirds collected during fall 2008; 2) extracted habitat (core) samples from the collection site and a random site for each bird to determine food selection and availability; 3) computed size-corrected body mass (a body condition index) for collected shorebirds in 2007 and 2008, and; 4) sorted and summarized ingesta from 152 shorebirds collected in 2007. We are currently processing food availability samples from 2007 and will begin analysis of ingested food and habitat samples from 2008 collections.INHS Technical Report Prepared for U.S. Fish and Wildlife Servic
