HMANA is the only organization that collects, analyzes, and publishes hawk migration data from
hundreds of hawkwatch sites on a continental scale. Results are published in the biannual
journal, Hawk Migration Studies (HMS).
All contributions to HMANA support research projects including Raptor Population
index (RPI), the HawkCount.org website, and the BIRDHAWK email list. Support from hawk
watchers like yourself is essential to HMANA’s operations and to promoting and sustaining an
appreciation of raptor migration!
