American Robin, Chignik Lake, Alaska Peninsula, May 20, 2019
Having long associated American Robins with manicured lawns in the Lower 48, I was mildly surprised the first time I encountered the species along the Chignik River. They were not reported in David Narver’s Birds of the Chignik River Drainage study based on his observations in the early 1960’s, and although they are considered common further up the peninsula, from Aniakchak National Monument and Preserve (which encompasses much of the Chignik Drainage) all the way to Izembek National Wildlife Refuge near the peninsula’s western tip, the species is either not documented at all or is listed as only an occasional migrant.
For the most part, that’s how we encountered them at and near The Lake – a few birds passing through in mid-spring, late summer and early fall. But, they seem to gradually be establishing themselves along the Chignik. In two years, at least one pair remained late into spring, well after the peak of the dandelion bloom. We thought that in at least one of those late springs a pair of robins had attempted to nest. However, the weather became persistently cold, rainy and windy and there was no indication of success.
Along with the weather, abundant magpies and ravens – well-known nest predators – might be limiting factors to breeding robins. Nonetheless, it is likely only a matter of time before American Robins become established as regular nesters on the peninsula, particularly in villages such as Chignik Lake where lawns provide easy access to the earthworms they like to forage on.
