Quarter-Month Status
Birds of Plum Island, Essex County, Massachusetts
Ordered by Number of Sightings

Compiled by Tom Wetmore


This table shows the quarter-month status of the birds of Plum Island. It is based primarily on data I have collected over the past five years. The species are listed in the order of their numbers of sightings. The column labeled ‘n’ orders the species. The column labeled ‘N’ shows the number of different days that each species has been reported on the island over the period of data collection. Birds that have been seen between two and 99 times have a second number in their ‘N’ column. This is the number of years that the species has been seen recorded. Cells in these two columns may be colored. Red cells indicate species that just moved up in the ordering. Blue cells indicate species that just moved down. Yellow cells indicate species that were seen on the last day of sightings.
