Atlas Results
Although the Pacific Wren has previously nested in the Cypress Hills, only probable evidence was obtained at one site during the atlas and the species remains a rarity in Saskatchewan. In mid-July 2020, an individual was heard and recorded singing on two occasions eight days apart near the Fort Walsh Historic Site.
Excerpts Adapted from the Birds of Saskatchewan:
The Pacific Wren is a rare summer resident in Saskatchewan only in the Cypress Hills of the extreme southwest. Based on plumage alone, the Pacific Wren is often virtually indistinguishable from the Winter Wren (T. hiemalis) from which it was recently split. A permanent resident of the Pacific Coast from Alaska to California it breeds into western Alberta and Montana with isolated breeding locations as far east as Saskatchewan, South Dakota, Wyoming and Arizona.
Found in mixed conifer-deciduous riparian forest containing deadfall, root wads, woody debris, snags and slash piles (Toews and Irwin 2020).
The first confirmed record of a Pacific Wren in Saskatchewan was made in the Centre Block of Cypress Hills Interprovincial Park 24 Jun, 2015 (SEF ). The few historical records of Winter Wren from the Cypress Hills are now considered to be Pacific Wren. In every case where there is a subspecies or sibling species pair of birds-one in the boreal forest and the other in the mountains-the form in the Cypress Hills is always the mountain form. Examples include Yellow-bellied and Red-naped Sapsuckers, Mourning and MacGillivray's Warblers, and Slate-colored and Oregon Juncos.
