Peter is correct.
The bird lists are based on bird distributions within your selected
one-degree square, and represent what you may reasonably expect given a full
range of habitats and long period of observation. Vagrants are not included.
I think of them as 'maximum potential' lists, as opposed to observed lists
which represent limited areas, habitats and observation times. In an
Australian context the degree square is quite a small area, but does mean
that coastal areas may have a mix of inland, coastal and even sea birds on
the list. The lists are however intended as shortlists to 'work from' in
making your own list, and avoid having to scroll though 900 species when
doing so.
The birding site lists are also available from the My Location map, and
these use a smaller area for the lists. I will however look into using a
smaller distribution area for an app update. Perhaps we can refine those
lists a bit more. And yes, you do have to select an area to get a bird list.
This is done by either selecting 'current location', or using the drop pin
for a new location.
As an aside, the Windows PC app has additional functionality in that you can
'draw' a much smaller area, colour in a larger area, or trace a route.

I think it generates the list for the the one degree "square" of latitude
and longitude of your position, which works out to about 100km square at
that latitude, so you should certainly get more than coastal species listed.
I think you also have to nominate the location of that "square", so perhaps
something went wrong with that too.
