Where do saw-whet owls live across North America? Please provide details about their preferred habitats, including specific regions or environments they favor, such as forests, woodlands, or other ecosystems. Additionally, mention any seasonal movements or migrations they may undertake.
Answer
Saw-whet owls primarily inhabit North America, where they can be found in a variety of forested environments. Their range extends from southern Canada through the contiguous United States, and they are also present in parts of Mexico. These nocturnal birds prefer dense coniferous, mixed, and deciduous forests, often occupying areas with a thick understory for roosting and nesting. During the breeding season, they are more commonly found in regions with abundant food sources, such as small mammals, which make up a significant part of their diet. In winter, saw-whet owls may migrate southward, seeking warmer areas and suitable habitats. They can occasionally be found in urban settings, particularly during migrations, if there is adequate cover and food availability.
