In areas with bright street lights, robins may sing all night long. Jim is right that they usually wait till 1-2 hours before sunrise. Some researchers believe that they sing so early so they can get that over with by first light, so they can take advantage of the first light to search for earthworms before the rising sun sends the worms back to their subterranean burrows.
Robins were back singing in Duluth in my neighborhood this weekend.

There is something infinitely healing in the repeated refrains of nature--the assurance that dawn comes after night, and spring after the winter. —Rachel Carson Please consider the environment before printing this e-mail. ---- Join or Leave mou-net: http://lists.umn.edu/cgi-bin/wa?SUBED1=mou-net Archives: http://lists.umn.edu/archives/mou-net.html
