In the vast expanses of North America, a total of 11 wren species have been observed, and among them, a remarkable 8 have been spotted in the beautiful state of Utah. The wrens that grace the skies of Utah consist of seven regularly occurring species and one accidental visitor. For those curious souls yearning to identify these avian creatures based on both their visual appearance and melodious calls, fear not, for this guide shall illuminate your path.
Utah plays host to several wren species that reside there throughout the year, including the Marsh Wren, Rock Wren, Canyon Wren, Bewick’s Wren, and Cactus Wren. These birds, with their unassuming appearances, brown plumage, and plump physiques, possess charismatic personalities, accompanied by upright tails and resonant voices that echo through the air.
The wrens that grace the lands of Utah during the summer season are primarily represented by the House Wren. As for the other wren species that one may chance upon in this region, keep an eye out for the Pacific Wren and the Winter Wren. These charming creatures belong to the New World, encompassing the vast expanse of the Americas, except for the Eurasian Wren, which calls Europe and Africa its home.

Utah’s Splendid Array of Wren Species:
1. Marsh Wren
Behold the Marsh Wren, a year-round resident of Utah. These delightful creatures make their presence known on 4% of summer checklists and 2% of winter checklists.
Marsh Wrens possess brown feathers adorned with black and white streaks upon their backs. Their grayish-brown underbellies provide a striking contrast, while their hallmark upright tails stand as testaments to their wren identity.
They lack shoulder stripes and boast longer bills compared to their Sedge Wren counterparts. Interestingly, both male and female Marsh Wrens share the same appearance.
Scientific name: Cistothorus palustris
Length: 3.9-5.5 in (10-14 cm)
Weight: 0.3-0.5 oz (9-14 g)
Wingspan: 5.9 in (15 cm)
Marsh Wrens breed in the northern states of the United States and central regions of Canada, journeying south to the Southern states and Mexico during migration. During this time, Marsh Wrens can be spotted in the Eastern United States.
To catch a glimpse of Marsh Wrens, venture into wetlands
where they cling to reeds, utilizing their nimble feet to grasp multiple stalks. Though their diminutive size may pose a challenge, their distinctive songs often pierce the air during the tranquil hours of dawn and dusk.
Feasting primarily on insects and spiders, Marsh Wrens meticulously pick their prey from leaves in close proximity to the water’s edge.
If you happen to encounter the auditory delight of a Marsh Wren, its song is characterized by a distinctive, buzzy melody that can persist for a staggering 20 minutes.
It is worth noting that Marsh Wren nests boast a fully enclosed structure, save for a small opening at the top. Woven from reeds and grasses, these nests harbor 3-10 eggs, which incubate for approximately two weeks before hatching. Another two weeks are then required for the chicks to fledge.

House Wrens, while lacking in melodious tunes, compensate with their frequent vocalizations. Their songs consist of a medley of jumbled notes, transitioning in pitch and speed.
When it comes to nesting, House Wrens opt for old woodpecker holes, nest boxes, or other small crevices. They exhibit a preference for lightly wooded areas, fashioning their nests from twigs and lining them with softer materials.
