As a reminder, here is what each rarity code means:
**Rarity Codes:
1 = common, always seen in habitat in season.
2 = fairly common, usually in habitat in season, but missed sometimes.
3 = uncommon, always around, but sometimes you can't find.
4 = rare, occurs yearly in the county, but not always in same places.
5 = very rare, does not occur every year.
6 = casual or vagrant, generally fewer than 10 records.
Do not disclose information that identifies the location of nesting birds of any species, to minimize stress on the nesting birds and the risk of vandalism or abuse.
