Damon McDermott, a student at the University of Memphis, is studying raptors
and urbanization in the Memphis area and would appreciate learning of any
raptor nests there. Please contact him directly.
Thanks,

Mr. Nicholson,
Thank you for the link to the bird count data it will be of help. I am
looking for nesting sites for raptors in the Memphis area to gather pellets
for research if you know of any or know anyone who would it would be of
value. I know of two pair of Red Tailed Hawks that nest near campus others
would help.
Thank You,
Damon McDermott

Damon,
I don't know of any studies that have directly addressed the issue of the
effects of urbanization on raptors in the Memphis area. You might look at
the trends in the results of some of the Christmas Bird Counts in the
region. Although these would not directly answer your questions, they would
show changes over time on winter counts held in a fixed area for many years.
You might find that there are differences in the population trends for
individual species between counts in urban and rural areas. There is a
Memphis Christmas Bird Count that goes back many decades, and there are some
counts in nearby more rural areas of Tennessee, Mississippi, and Arkansas;
few of these have as long a historical record as does the Memphis count.
Also keep in mind that there are other factors that cause year-to-year
differences n the count results besides urbanization. These include count
effort (many analysts standardize for this by analyzing the number of
individuals of a particular species per count party-hour (e.g., the number
of that species observed divided by count party hours, a unit of effort)),
trends in raptor numbers unrelated to urbanization (e.g., some species have
shown increases since pesticides such as DDT were banned in the 1970s), etc.
Christmas Bird Count data can be accessed at
http://www.audubon.org/bird/cbc/
I think I have seen citations for studies of the effects of urbanization on
birds (not just raptors) conducted elsewhere. You might search for these in
the various online bibliographic databases available at your school. These
should be helpful.
Best wishes on this project.

Hello,
My name is Damon McDermott and I am a biology student at the
University of Memphis. I am trying to do a study on the urbanization
of raptors in this area and I am looking for data on the numbers of
raptors in urban areas versus rual areas. Do you know where I would
be able to find counts for such a study.
Thank you
Damon McDermott
