On average, it takes a bird anywhere from about 2 days to 2 weeks to build a nest. The exact duration depends on several factors including the bird species, the complexity of the nest, availability of materials, weather conditions, and whether both male and female birds participate in the construction
. Some specific examples:
- Sparrows can build a nest in about 2 days.
- Eastern Bluebirds take 2-6 days.
- American Goldfinches take around 5 days.
- House Wrens and European Robins take about a week.
- Barn Swallows may take up to two or three weeks
The type of nest also influences the time required: elaborate woven nests or nests with thick insulation in colder climates take longer, whereas minimalist nests or those in warmer areas are quicker to build
. In some species like cavity nesters (e.g., bluebirds), nest building can take 3-4 days up to 2 weeks, sometimes preceded by excavation that may take longer
. Thus, while the typical range is 2 days to 2 weeks, some birds with more complex nests or special nesting habits may take longer.
