*The separate Bay, Berrien & Washtenaw Co. databases were discontinued due to workload
- Develop sighting report submission forms
for each Michigan county - In Process
NMB Database Project Late and Early Dates.
This element of the database project develops
master lists for early and late dates in
the spring and fall for migratory species
in Michigan. We will build master lists for
Michigan as a whole and for Washtenaw and
Berrien Counties. These early and late date
lists will be integrated into the NMB seasonal
databases.
- Michigan Early and Late date master list.
- In Process
In developing this project we are focusing
first on those counties that regularly report
and report a larger number of sightings data
than other counties.
Database Project Overview The underlying charter of the NMB Database
Project is to offer interested people a "snap-shot"
of birds sighted in Michigan in a database
format that allows flexibility in searching
from an individual's specific interests. Our
long-term goal is to eventually develop the
database to a point were it can be used as
a Natural History resource.Currently the
data in the Spring, Summer and Fall databases
is used by the compilers of the Michigan
Bird Survey and is used in the Michigan Birds
and Natural History magazine.The database
administrator - Dee Miller - gathers sighting
reports from Michigan bird sighting email
lists, message boards, among other sources.
This "data" is then processed to
the database.
(The project was suspended for several years due to health concerns and is being resumed on a trial basis)
Understanding the Plot Map and its relationship
to the database data.
Click on the map image above to view the
grid. One click shows the grid and two clicks
shows the grid with numbers. When first loaded,
the map displays all the sightings. To view
the sightings individually click on the button
the says "1 by 1". Then you may
cycle through the sightings.
Please note repeat sightings show as one
dot on the plot map when viewing all the
sightings at once. When viewing the sightings
individually on the map all sightings will
be displayed. Also the records reported from
the database follow the order on the map.
Michigan is captured in 53 blocks on the
map.
Pieter Gordijn explains the plot map coordinate
system in this way:
A full block measures 40km by 25km and has
a West and East part. But some blocks near
the border only contain a west or east part
(for example block 8W and 24E). Blocks are
divided in 5km x 5km squares which are numbered
according to the table beneath. |

These 5km x 5km squares are divided in 25
1km x 1km squares and are numbered as follows:

With the additional information in the observation
code, the location of a bird can be accurately
described within a 500m x 500m area.
