Hi Mark,
I believe eBird (www.ebird.org) can help you with portraying the data you
like to query. I've been using it since 2007, and find it very fun, and an
excellent way of keeping records. There are also two iPad apps,
Birdwatcher's Diary and BirdLog (soon to have an Australian version,
currently world) that feed easily and directly into the eBird database. I
use the former.
To address what you are trying to do.
By clicking on "Summarise my observations", selecting a location/s, and a
period of time, eBird can:
- Show you the number of times you've seen a species at a particular
site (Ash Island, for example) this year;
- Show you a list of the species you've recorded at Ash Island, and the
number of occurrences of each species;
- Show the frequency (as a percentage) of each species seen at Ash
Island that year;
- Your last point can be achieved by clicking on your year list, then
selecting any species. Clicking on the species will bring up a table with
count/location/date information for all your observations of that species
you've recorded that year.
- You can also enter age group/sex data for your records, as well as
produce many other stats, including bar charts (showing a visual
representation of changing bird abundances on week/month basis for
example), maps and graphs
eBird launched in 2002 and is a global database/listing program, which has
become so popular and user-friendly, that as of last month, has broken the
100,000,000 submitted observations barrier!
Hope this helps.
Cheers
