It seems that Stelco has probably left on migration. Another female has shown up at the nest. She is W.C. from Lima, Ohio, band black/green M/34. She was there last winter, but Stelco returned in the Spring. The resident male, M.P. (stands for Moores Park) is still there, and he and W.C. have been spending time in the nest box. Haven't seen them there yet, but I have seen pics.
