Dave Nutter described the David Cup area. Has anyone developed a digital map with boundaries as described below? Is the map in the CBC guide to the basin accurate? There is a map on the Cayuga Bird Club website, but seems to contradict some of the comments below. For example the Owasco Outlet comment. Advice would be appreciated. tk
5. David Cup birds must be in the Cayuga Lake Basin as defined by the 1926(?) botany textbook by Wiegand & Eames. The map used to be on the Cayuga Bird Club website, and we should be able to find a copy on the web somewhere, or get one to you. This basin includes the land which drains into Cayuga Lake, which makes the south and middle parts of the basin pretty easy to determine. More confusingly, it also includes lands to the north which drain into the Erie Canal, Clyde River, and Seneca River rather than draining north directly toward Lake Ontario. The east and west boundaries of the northern basin are marked on that map, but are a bit arbitrary, and surprisingly broad, supposedly to include interesting botanical areas. To the east it includes Crane Brook (thus the western edge of the City of Auburn), the Owasco Outlet downstream of NYS-38, and the Seneca River east to just north of Weedsport (but it does NOT include Port Byron or Weedsport). INCLUDED are Howland Island, Duck Lake, Mud Pond, Slayton Pond and Stark Pond and associated drainages. In the west, the north-draining lands include Silver Creek and the next small stream to the west but not Kendig Creek. Seneca Lake and its drainage are NOT included. The Seneca River itself is the border west just beyond Packwood Road, then the border goes west and then north between the Ontario/Seneca County Line and NYS-14 so as to include the southeast-flowing Black Brook, the Junius Ponds, Burnett Pond (not sure how the drainage allows this), north-flowing Pond Brook, a strip of the Town of Lyons (but not the Village of Lyons), and a different south-flowing Black Brook. The northern border is tricky to determine at a fine scale because of the chaos created by the huge field of drumlins and various drainage ditches in farmland and along roads, but the general principle holds: any stream leading directly to Lake Ontario is OUT. -- Cayugabirds-L List Info: http://www.NortheastBirding.com/CayugabirdsWELCOME http://www.NortheastBirding.com/CayugabirdsRULES http://www.NortheastBirding.com/CayugabirdsSubscribeConfigurationLeave.htm ARCHIVES: 1) http://www.mail-archive.com/[email protected]/maillist.html 2) http://www.surfbirds.com/birdingmail/Group/Cayugabirds 3) http://birdingonthe.net/mailinglists/CAYU.html Please submit your observations to eBird: http://ebird.org/content/ebird/ --
