Topic: Grey Plover flight period rule error?

I am in the process of capturing bird data and I believe the rule for the Grey Plover flight period is wrong. Can anyone confirm my suspicions? the rule is:

TestType=PeriodWithinYear
Group=Birds Flight Period
ShortName=Grey Plover
Description=Checks date is within most regular occurrence period for Grey Plover
ErrorMsg=Date is outside usual flight period of Grey Plover
Tvk=NBNSYS0000000141
DataFieldName=
StartDate=0701
EndDate=0531
LastChanged=20110713
[EndMetadata]

I believe this should be a reverse rule can anyone confirm?

I don't know the format of the record centre rules to know what the rule is saying, but the main occurrence period for Grey Plover is all months except for June and July if that helps (i.e. main occurrence period Jan-May and Aug-Dec).

Re: Grey Plover flight period rule error?

Thank you TeresaF, I have had an email confirmation from BTO about the dates too and so I have amended my Grey Plover rule locally to be a reverse rule as below, this has now corrected the error. The original rule only accepted GP's that occurred in the 2 months they are not usually present. Thanks again.
