Application of GIS to Home Range Analysis in the Island Scrub Jay. (Rodd Kelsey
California State University 5331 The Toledo Long Beach, CA 90803 Telephone:
310-439-4025 Fax: E-mail: roddk@aol.com). The Island Scrub Jay (Aphelocoma
insularis) is an endemic bird species on Santa Cruz Island, California.
A significant amount of work has been accomplished over the last twenty
years concerning the demography of this species. However, very little
work has been completed on its home range and habitat utilization. The
jay defends territories in a variety of habitats across the Island. I
will determine home range size in different habitats across the Island.
In addition, these home range sizes will be utilized to estimate Island
population that can then be applied to minimum viable population analysis.
This study will use GIS techniques to map territories and estimate total
Island population size. Scanned aerial photos will be georectified and
used for digitizing spots maps obtained in the field. The coordinates
for these territories will then be exported to CALHOME, an external home
range analysis program. Once home range sizes are determined, they will be
combined with existing digital vegetation maps to estimate total population size.
Applying GIS and Remote Sensing to Avian Research: A Case Study on the Ouachita
National Forest (1996 Paper, Robert C. Weih, Philip A. Tappe, Chris
W. Bennett, Ronald E. Thill)...After collating the GIS layers, 524 bird
census points were established along 72 miles of transect. The transects
were positioned to sample many different combinations of vegetation spectral
types and physical features of the landscape, as determined by the GIS
analysis. All bird census points were then located in the field and their
positions recorded with differentially corrected Global Positioning System
(GPS) coordinates. Habitat information such as basal area, canopy height,
canopy coverage, vegetation density, and vegetation vertical profiles
were also measured at each bird census point....The spatial arrangement
of these categories was used to examine previously over or under sampled
areas and to modify bird census points for the 1996 sampling season. In
addition, analyses of avian communities as they relate to stand and landscape
level habitat parameters were initiated that incorporated the spatial
modeling features of GIS.
Migration Maps for Some North American Neotropical Migrants, by Sam Droege and

the 1993 Migration Monitoring Workshop. Data were scavenged from a diverse
set of bird banding sites and counting programs."
Multi-scale analysis of bird species relationships by Anne Black, Point Reyes
Bird Observatory "Nearly 20 years ago, The Nature Conservancy began
restoring natural habitats and flooding regimes in its Cosumnes Nature
Preserve....PRBO has been monitoring bird communities in these newly restored
sites for the past 10 years. This summer, we will be initiating the first
analysis of this data to answer the questions: how do bird communities
respond to restoration, and which restoration techniques seem to provide
the 'best' habitat most quickly?"
