|Documenting Migrant, Vagrant, and Non-breeding
Only submit documentation for migrant, vagrant, and nonbreeding species
(MVN) if it is outside of its normal migratory pathway. For example,
a Western Kingbird sighting on a BBS route in Maryland should be supported
with some documentation of the observation. The same would hold true
for a Yellow-throated Vireo in California. Basically, if a state’s
rare bird committee would require documentation of the MVN, then documentation
should also be sent to the BBS office. The report should contain the
- Field marks and/or behavioral characteristics that were used
to identify the species.
- Duration of observation (i.e. fleeting glance, a full-minute,
- Distance from observer.
- Type of optics used to view species (i.e., 7 x 35 binos., 10
x 40 binos., none, etc.).
- Type of habitat where species was detected.
- Similar species in area and how they were ruled out.
