The 1984 Christmas Bird Counts in Eastern Massachusetts
Notice bibliographique
Résumé
The Eighty-fifth Annual Christinas Bird Count (CBC) sponsored by the National Audubon Society was held from December 15, 1984 to January 2, 1985.The count data for the 1983 CBC was published in American Birds, July-August 1984, and included 1246 count circles in the United States, 186 in Canada, and, added in that year, 19 in Central and South America, and 9 in the West Indies.This report includes capsule accounts of the CBCs conducted in Eastern Massachusetts in December 1984, and the accompanying map shows all the count circles in the state drawn according to their locations published in the July-August issue of American Birds.A grand total of 190 species was recorded on the twenty-one eastern Massachusetts counts.Two additional races, the Ipswich Sparrow and the Oregon Junco, and one escape, the Red-crested Cardinal found at Arnold Arboretum in Boston, were also recorded.Another four species and one additional subspecies escaped the official tally for the Christmas Count Day but were noted during the count period (three days before and after).These were Green-backed Heron, Wild Turkey, Swainson's Thrush, Prairie Warbler, and a.Bullock's Oriole.Imagine 194 species in Decev.iber in Massachusetts!No doubt, the very warm month had a great deal to do with the exceptional high counts reported.The temperature of 73° on December 29 broke all previous records.All water was open, and this contributed to higher counts in inland locations where, more often than not, ponds are sometimes frozen by mid-December.The wild food crop was also very good, and the birds that eat fruit or berries such as American Robins and Cedar Waxwings were on hand in record numbers.The Cape Cod CBC, as usual, led all counts with 133 species recorded; the Greater Boston Count showed a surprising second-place finish with 129 species.The Millis CBC boasted the highest number of participants (326), but even this number of observers could not find as many Blackcapped Chickadees as the Concord Count, whose annual total of that species exceeds all other totals on the continent.Map on ^aCA.ngpage.: Each Christmas Count circle was located by the latitude and longitude (in degrees and minutes) of its center as given in the July-August 1984 issue of American Birds.Circles were drawn on a large, regional map which was reduced to the size shown here.Detailed topographic maps should be consulted to determine the precise boundaries of each circle.Athol (1), Buzzards Bay (2), Cape Ann (3), Cape Cod (4), Central Berk shire (5), Concord (6), Greater Boston (7), Greenfield (8), Marshfield (9), Martha's Vineyard (10), Mid Cape Cod (11), Millis(12), Nantucket (13), New Bedford (14), Newburyport (15), Northampton (16), Northern Berkshire (17), Plymouth (18), Quincy (19), Springfield (20), Taunton-Middleboro (21), Tuckernuck Island (22) , Uxbridge (23), Westminster (24) , Worcester (25), and Newport County, R.I./Westport (26).

Prédiction machine sur la base complète
Imitation des enseignantsNi prévalence calibrée, ni vérité terrain. Validation humaine à venir. Le volet Gemma est une étiquette directe du modèle pour chaque travail de la base, lue sur la notice réduite au titre. Le volet Codex est un classifieur appris des 10 348 étiquettes directes de Codex et calibré sur les taux pondérés de l'échantillon; les champs sans appui suffisant ne portent aucun appel Codex. Le mode candidate est l'union des deux volets; le consensus est leur intersection. Ces sorties portent le statut machine_predicted_unvalidated et ne sont pas des étiquettes humaines.
