Hummingbirds are known as the top migrant birds in the world due to their ability to travel long distances in search of warmer regions with abundant food. In Colorado, these tiny birds are attracted to the diverse landscapes, including the Rocky Mountains, which offer a variety of flowers that provide nectar, their primary food source. As a result, up to 10 different species of hummingbirds can be observed in Colorado each year. However, the distribution of these birds across the state is not uniform, so the likelihood of sighting them depends on your location within Colorado.
This article aims to discuss the timing of hummingbird departures from Colorado and how to prepare for their anticipated visits each year. It will also provide information on the reasons why hummingbirds leave Colorado, the common species found in the state, their arrival times, and where they can be found. Additionally, it will offer tips on attracting hummingbirds to your space and keeping your garden hummingbird-friendly.
When Do Hummingbirds Leave Colorado?
Hummingbirds typically begin their departure from Colorado as early as July, although some species may choose to leave later, around September.

However, it is not uncommon to find a few old or injured hummingbirds that are unable to migrate and remain in Colorado during the winter.
Why Do Hummingbirds Leave Colorado?
Hummingbirds leave Colorado every year for several reasons. Firstly, they have instinctual biological migration cues that prompt their departure. Their migration timing is guided by their innate circadian and circannual rhythms. Secondly, as winter approaches, their food sources from flowers and insects become scarce, driving them to migrate in search of more abundant food. Lastly, Colorado’s harsh winters force these tiny birds to fly south in search of warmer regions that offer better chances of survival.
