Publications Authored by Bloom

We strive to provide access to these peer-reviewed publications, for both scholars and the public, so that everyone can understand the issues facing our local raptor species in California and the western United States. Certain articles are already open-access by the publishing journal - those are linked below. If you would like to request a copy of any non-linked article listed below, please contact us.
