•PURPOSE:
–To determine to what
extent saw-whets migrate through PA - found to be a common migrant, and the
project moved on to other issues:
–Monitor long-term changes
in Saw-whet owl populations
–Track the time of
migration of age/sex groups
–Study stopover
paterns
–Study molt and other
aspects of biology
–Migration Routes: To determine what routes
the owls are using: broad fronts, ridges, and/or vegetation
corridors
–
•SITE DATA RECORDED:
–Time of opening nets and
closing nets
–Weather on opening and
closing site: temp, wind, precipitation, cloud cover
–Moon phase: the data from the 3
previous years indicates darker nights produce more owls…except
right at New Moon, suggesting owl like it dark, but not too dark.
–Identity of banders and
volunteers
