Abstract

Two hundred and eighty-nine species (plus the possibility that the Empidonax sp. was one not listed) are listed in this report, from 13 locations, plus 36 counties reported in 7 "spot check" columns or as notes in regular columns. In 1988 there were 306 species from 15 locations plus 13 "spot check" columns involving 34 counties; in 1987 288 species from 13 locations and 6 "spot check" columns involving 9 counties; 1986 304 from 13 locations and 9 "spot check" columns involving 24 counties; and 1985 296 from 13 locations and 9 "spot check" columns (plus additions on NBR 53:70) involving 22 counties.

The "spot check" columns are for infrequent visits to an area, and the lack of n entry for a particular species may be due to visits at the wrong time, or inadequate observing time. The average reader can just take the symbols in these columns as indicating that the species was present; those who want to know when and in which county can get that information from the symbols, which are given separately for each column. The symbols have different significance in each column.
