Abstract

During sub-zero temperatures and strong winds on 10–11 April 2013, we witnessed ice accumulation on plastic collars of staging Greenland white-fronted geese Anser albifrons flavirostris in Iceland. Ice affected 19 of 77 collared individuals seen, all of which had lost ice by 12 April, despite continuing freezing temperatures. Temperatures exceeded freezing after 14 April; daily observations found no recurrence of ice formation before geese left for Greenland in early May. Abdominal profile scores (a field assessment of accumulated body fat) did not differ significantly between geese with and without ice before departure from Iceland. There was no significant difference in return rates between geese with iced (79 %) or un-iced collars (83 %) reported the following autumn. These first reports of collar icing in over 30 years of the project give cause for concern and vigilance, but we recommend continued use of collars given exceptional weather conditions and lack of effects.
