Here are some eBird results --
After Charles Barnard's last sighting of the Northern Shrike on 29 April, there
have been 4 reports for Sully Woodlands, May 1 through 10, from 3 different
people. It looks like the bird finally left. I hope it has a nice summer and
comes back!!
The last report, April 29, was 6 months and 2 days after it was first seen here.
