Peregrine Falcon Monitoring:
Monitor the Recovery of Peregrine Falcons on the Channel Islands
This action proposes to develop a comprehensive program to monitor the recovery of the peregrine falcon on the Channel Islands. This program
would monitor the distribution, number of pairs, reproductive success (i.e., productivity), recruitment, foraging behavior, and dispersal of
peregrine falcons on the Channel Islands. An essential part of this program would also include contaminant analysis of addled eggs and eggshell
measurements, particularly in light of the lack of current data on levels of eggshell thinning and the potential ongoing effect of DDT
contamination. The monitoring program would be designed such that data are comparable to previous studies on the Channel Islands (such as the
study conducted in 1992). The scope of the monitoring program (including its frequency and intensity) would be developed in consultation with
experts. The estimated cost for comprehensive monitoring to occur twice within Phase 1 of implementation is $250,000.
Project Update 2007
In February 2007, the Montrose Settlements Restoration Program funded
biologists from the Santa Cruz
Predatory Bird Research Group 
to undertake the first monitoring effort for Phase I. Biologists spent many
weeks conducting aerial and on-the-ground surveys of the islands.

In April, for the first time in over 50 years, biologists discovered a pair of peregrine falcon chicks and an unhatched egg on Santa Barbara Island. Read

Approximately 3 weeks later, biologists attached small metal tags on both legs of each chick. The tags allow biologists to identify the chicks individually, and track them into adulthood. |
