The metric Universal Transverse Mercator (UTM) coordinates were pretty convenient for pinpointing locations on printed USGS topos, as UTM grid ticks are shown in the margins. The block grid of the New York State Breeding Bird Atlas follows UTM. I still have a few USGS sheets on which I drew the BBA grid, and I did the same in my old DeLorme's Atlas. But for casual birding navigation I vote for decimal lat & long.
