You can limit your selection by species, by location, or by both. If you try to list
all species at all locations you would generate a ridiculous number of hits, so you will
just get an error message.
Other requests may generate enough hits to choke your web browser. For example,
there are well over 15,000 Oxbow sightings recorded. You may choose to set a maximum
number of sightings to receive at a time.
You may also choose to sort the records by year, then by month, then by day;
or by month, then by day, then by year. The former will give a chronological list of
sightings, but the latter may be more useful if you want to see when a species may be expected.
