Being New World inhabitants, wrens have claimed territories in both North and South America, with the exception of the Eurasian Wren, which resides in the realms of Europe and Africa. These captivating creatures belong to the esteemed avian family known as Troglodyidae.
Due to their dietary preferences, consisting primarily of insects and spiders, wrens have the ability to survive in harsher environments, including arid and rocky landscapes with sparse vegetation.

Beetles, caterpillars, flies, and even snail shells serve as delicacies for these voracious insectivores.
When it comes to vocalization, House Wrens may lack tunefulness, but they compensate through a medley of disjointed notes, modulating in pitch and tempo.
In terms of nesting, House Wrens exhibit a fondness for repurposing old woodpecker holes, nest boxes, and various nooks and crannies. They favor sparsely wooded areas and construct nests from twigs, carefully lined with softer materials. The female lays 3 to 10 eggs, requiring approximately two weeks for hatching, with an additional fortnight for the chicks to take flight.
