Abstract
Fall 1990 Occurrence Report
During the period from 1 July to 31 December 1990, 284 species were recorded in the state. This compares with 291 species in the second half of 1989, 282 species in 1988, 296 in 1987, and 293 in 1986. The map below gives a representation of the frequency of reports within the state.
The report which follows gives information on reporting counties in a rough west to- east order. Counties of similar longitude are dealt with in a north-to-south fashion with some consideration for keeping counties along river valleys together. Those counties whose data is found within the occurrence tables are denoted in capital letters. One change to note: species recorded by observers as NR (not observed during count period but birds which observer is sure were present) are listed in the county-by-county report rather than the occurrence tables.
