Hi birders,
I live in Superior and have enjoyed watching several largish colonies of Cliff Swallows (dozens of nests) around town for many years. However, starting this year, several of these nesting areas are completely unoccupied even though the mud nests themselves are still largely intact. Has anyone else seen something like this? Any idea what might cause it?
Thanks, Peter Ruprecht Superior
