What Happens To Your Reports

Individuals who submit reports on hawk migration in eastern Massachusetts and Rhode Island contribute significantly to our knowledge of hawk migration locally and on much a broader scale.

Local Published Reports
The data submitted to EMHW are published in the annual Fall and Spring EMHW Reports, sent to about 225 members. The data is also submitted to Bird Observer, our Massachusetts birding magazine of record.

Online Reports
Preliminary data phoned in to the hotline or emailed in will be posted on MassBird, the Massachusetts birding listserv. Major reports will also be posted to
Birdhawk, the listserv for the Hawk Migration Association of North America. At any time you can also view recent daily reports for many hawk watches, as well as daily, monthly and seasonal tallies for many sites for the past several years.

Regional & International Reports
All of our - your - data is then forwarded to the NorthEast Hawk Watch (NEHW), which we believe to be the oldest continuous regional hawk watch in the world. NEHW consolidates our data into its annual NEHW Report on migration throughout New England and portions of New York and New Jersey. Our data is then passed on to the Hawk Migration Association of North America (HMANA), which publishes two seasonal reports on migration throughout North America and makes the data available to the government, academia, and amateurs for research and analysis.

Electronic Databases
Gradually, HMANA data is being entered into an electronic database, to make it more easily available to researchers. This is why HMANA is encouraging people to enter and submit their data digitally, to facilitate data entry and access for researchers, both professional and amateur.

How Your Data is Used
Data is analyzed at all levels, and there is much to be learned. Over the past twenty-five years, we have documented a significant hawk migration, particularly through the central part of the state. The data indicates a significant increase in the number of Turkey Vultures, Ospreys, Bald Eagles, Cooper's Hawks, Merlins and Peregrine Falcons migrating through the region. We've also documented an apparent decline in the number of Northern Harriers, Sharp-shinned Hawks, and American Kestrels migrating through the area. We're learning more about what time of day the various species of hawks tend to migrate, and which weather conditions are more favorable for migrating hawks and for hawkwatchers.

We've also seen a number of other creatures migrating, including large numbers of hummingbirds, gulls, cormorants, geese and crows, not to mention butterflies, particularly Monarchs. There's a lot to be seen while hawkwatching, and much to be learned.
