What is the incubation period for Ruby-Throated Hummingbird eggs?

The incubation period for Ruby-Throated Hummingbird eggs is indeed between 11 to 16 days. This duration reflects the natural reproductive cycle of these small birds, where the female typically lays a clutch of two eggs and then incubates them largely alone. During this time, the female remains committed to her nesting site, ensuring that the eggs are kept at the optimal temperature needed for proper development.

Choosing this answer aligns with established ornithological data, which has documented the egg-laying and hatching behaviors of Ruby-Throated Hummingbirds. Understanding this timeframe is crucial for anyone involved in wildlife management or birdwatching, as it offers insight into the nesting habits of these species and highlights the delicate balance required for their successful reproduction.
