Mark Cranford has approved the following request to Ontbirders: Should any carcasses or even partial remains of Red-necked Grebe become available during the remainder of the winter, Ontario birders are requested to preserve same in a freezer. Tissue samples, through stable isotope testing, could reveal whether these birds have spent the winter on freshwater or saltwater. Chip Weseloh (CWS) is prepared to undertake this testing, but first we need the specimens.
All contributions of specimen material will of course be gratefully acknowledged in any future publications. Please report the availability of Red-necked Grebe specimens to Chip Weseloh at: [EMAIL PROTECTED] See my article titled "Late Winter Red-necked Grebes: a Mystery" in the October 2003 issue of OFO News for a review of the "Frozen Out" and "Early Migration" hypotheses concerning winter incursions by this species.
