Information Request: Central Valley nesting White-faced Ibis
For those of you who do NOT subscribe to the Central Valley Birds list serv...
HI CVBirders, if anyone has information on nesting White-faced Ibis
in the central valley, please contact Rob Doster below. The email
also describes the project and request for information by the USFWS.
You can also request a spreadsheet from Rob to input your data.
In 2009, with the cooperation of many state partners, the Service's
Migratory Bird Program began the Western Colonial Waterbird Survey
(WCWS), a three-year initiative to identify information on
distribution and abundance of colonial waterbirds in the western U.S.
This survey is designed to determine the status of 17 species of
waterbirds so as to identify conservation issues and refine
conservation actions for these birds. This project also has the goals
of production of an atlas of these waterbird colonies and
establishing a baseline for long-term monitoring of waterbirds in the
west. (For more information, see:
In 2010 we are focusing a portion of this effort on the nesting
White-faced Ibis in California's Central Valley. I'm requesting your
assistance in identifying any active ibis colonies in the Central
Valley this year. If you know of White-faced Ibis colonies and have
information on their location(s), size, and nesting success, I would
appreciate your cooperation in providing these data to help with the
For your use, you may request from me a spreadsheet that is being
used in the WCWS. Use of this spreadsheet is optional. If you would
simply prefer to send me data via e-mail, I'll enter it into the
spreadsheet. At a minimum I would request that you submit to me
coordinates of colonies (UTM, NAD 83 preferred), the approximate size
of the colony (direct nest count, if possible, and number of
individual birds observed), and the conditions associated with your
observations (date, time, and weather conditions). I may need to
follow up with you for more information later as I compile the submissions.
Finally, if you can also suggest anyone else working in your area
that may know the whereabouts of nesting ibis, please share their
contact information with me.
If you have any questions regarding my request, please let me know.
Many thanks for your help in this effort.
