The same male captured in 2016, now an after second year male with a bold, distinct necklace.

During the breeding season, male songbirds often have brightly coloured and contrasting feather patterns to attract females. These patterns often become more pronounced and defined in older adult males. One of the distinguishing features of the Canada Warbler is the adult male’s dark necklaced feather pattern, which gets darker and more distinct after their second year. Not only did our banded male from 2015 return to the same breeding location, but he came back in 2016 sporting a beautifully developed necklace, and was accompanied by a nesting female! Looks like a year abroad did wonders for this warbler’s appeal. Post and photos by Anjolene Hunt.
