In my migration studies, I use four survey protocols: nocturnal =
migration, morning flight, diurnal migration, and stop-over. Morning =
flight is the first 3 hours after sunrise when both nocturnal and =
diurnal migrants can be in the air. Nocturnal surveys are 7 nights per =
week, and the others are two days per week. These four surveys can be =
further enhanced when collaborating with those using radar and/or bird =
banding.

I=E2=80=99m sure the comparison is possible but there are considerations =
that have to be taken into account. Off the top of my head a few =
factors that might skew eBird sightings are the following:
=C2=B7 How long a time frame do the observations represent?
=C2=B7 How big an area does the eBird location represent?
=C2=B7 At what time of day were the observations made?
=C2=B7 What species are to be analysed?
=C2=B7 How are resident birds taken into account versus migrants =
(if you are interested in migration)?

With this in mind eBird observations could be set up to use a standard =
protocol. It would have to be something like observer =
=E2=80=98A=E2=80=99 goes to location =E2=80=98A=E2=80=99, stands at such =
and such a spot and records all birds seen over =E2=80=98X=E2=80=99 =
minutes. It could be one point or many in a specified route. This would =
then be repeated every day or on most days through the season. It could =
be a short duration or a long one. It could be a breeding bird survey =
type protocol or a sea watch type protocol. eBird would simply act as a =
repository for the data but unlike other sources of eBird sightings the =
participants would know the data was standardized.
