What Does the Trochilus ourissia Eat?
The diet of the Trochilus ourissia primarily consists of nectar, which it extracts from a wide array of flowering plants. Its long, specialized bill and extendable tongue enable it to reach deep into tubular flowers, accessing nectar that many other animals cannot. This feeding behavior not only sustains the hummingbird but also facilitates the pollination of numerous plant species.
In addition to nectar, the Trochilus ourissia supplements its diet with small insects and spiders, providing essential protein for growth and development. This dietary component is particularly important during the breeding season, when the nutritional demands of egg production and chick rearing increase. The hummingbird employs a strategy of hawking, capturing insects mid-air, or gleaning them from foliage.
Seasonal variations in diet occur as the availability of floral resources changes. During periods of nectar scarcity, the bird may increase its intake of insects to meet its energy needs. Foraging typically peaks during the early morning and late afternoon, coinciding with the highest nectar production times in many plants. This strategic feeding schedule maximizes the bird's energy efficiency and supports its high metabolic rate.
