1st Week of August 2019 – Beaver River, Yarmouth County, Nova Scotia

There was a good combination of shorebird and warbler nocturnal movements this week. True migration seemed more apparent among the warblers. The two most common warblers were Black-and-white Warbler (an estimated 58 birds) and American Redstart (56 birds). The next two most

4th Week of July 2019-Beaver River, Yarmouth County, Nova Scotia

Nocturnal migration during this last week in July poses a number of interesting questions about the migration that takes place in mid-summer. By late July, peak migration for some shorebirds species is well underway. Beaver River is not a significant stop-over area
