The Maryland Ornithological Society's May Count has been an event since 1945. For the first 40+ years it was held on the first Saturday of May. Year after year, Garrett and Allegheny County participants complained that migration hadn't really kicked in on the first weekend of May, especially when the first Saturday was at or near May 1, and they were essentially getting mostly winters birds and very few Neotropical migrants. Sometime around 1980, +/- a few years, the count was moved to the second Saturday of May. The North American Migration Count started in the early 1990s and it too was held on the second Saturday of May. This was due to it being founded by Jim Stasz who coordinated the date with the Maryland May Count but some of the states in the southern U.S. used to complain that migration was essentially over for them by that date. This was unfounded because there are some nesters that don't arrive back on territory until around the second weekend of May (Sulphur-bellied Flycatcher is an example). The NAMC originally was set up to track data using County/Parrish boundaries. Though other methods on a smaller scale would be more accurate due to the vast size of some counties, logisticsand resources were an issue when the count was first launched. Initially, computers lacked the processing ability to separate and track the data using other methods. There was a significant limitation of manpower to process the nationwide data (Jim Stasz on a Windows 95 based PC) that had compiled on the state level by volunteers in each of those with counts. Then along came eBird and The Cornell Lab essentially took over the tracking of the NAMC data with the eBird program. Though they never officially made an agreement to do this and call it the NAMC, their ability to track all sighting on a single day accomplishes what the NAMC was founded to do. Cornell with eBird has the resources to do it in a far more accurate way than when done by hand on spreadsheets. Today there are still NAMC counts run throughout various sections of the U.S., including here in Maryland. Cornell introduced The Global Big Day in 2015 and held it on May 9th, the second Saturday of the month. It was held on the 14th in 2016 and the 13th in 2017. Then for some reason, the date was shifted by Cornell to the first Saturday, May 5th, in 2018 away from the NAMC date. They are continuing to run it on the first Saturday this year and it is unclear why.
