The first cerulean warbler of 2011 has returned to Opinicon Road. I found it singing infrequently on the north side of the road 100 m east of the Skycroft Campground sign. Request for information on Opinicon Road's cerulean warblers: There are 100-106 pairs of cerulean warblers breeding on the lands owned by the Queen's University Biological Station. Most are concentrated in 1,250 ha along Opinicon Road. Last year Paul Martin, Liz Purves and I colour banded about 85 males. Banding was part of a longterm monitoring programme, part of which hopes to determine return rates of banded birds. We'd appreciate reports of banded male (and female) cerulean warblers from Opinicon Road and its environs. If you would like to submit a sighting you can simply email me privately (mconboy@lakeheadu.ca). The only information I need form you is the band combination (each bird has 4 bands, 1 of which is always a standard silver CWS band and 3 plastic colour bands; each band combination is unique, no two ceruleans at QUBS wear the same combination) and a general location (i.e. near Skycroft Campground or 6 km from Perth Road, etc). Colour band combinations are usually reported as "top left/bottom left - top right/bottom right". For example today's cerulean warbler was wearing the colours white/white - white/silver. Please don't feel obligated to submit your sightings, but I'd welcome them from anyone who is interested in doing so. Thank you. Other recent migrants along Opinicon Road: scarlet tanager, common yellowthroat, blue-winged teal, brown thrasher, grey catbird. The orchard oriole originally found on 27th was present at Queen's University Biological Station again on the 28th but hasn't been seen since.
