Crotalaria cunninghamii - this form has distinctive green flowers in axillary clusters.. Crotalaria cunninghamii, also known as green bird flower, bird flower ratulpo, parrot pea, or regal bird flower, is a plant of the legume family Fabaceae, [1] named Crotalaria after the Greek word for rattle because their seeds rattle, and cunninghamii after early 19th-century botanist Allan Cunningham.
[28] [29] [26] The hummingbird itself will choose the plants its feeds from on the basis of its beak shape, its perch on the plant, and its territory choice. [30] Hummingbird visits to the Heliconia flower do not affect its production of nectar. [31] This may account for the flowers not having a consistent amount of nectar produced from flower ...
Individuals visiting Aquilegia chrysantha flowers in Pima County, AZ, had proboscis lengths very similar to the length of the nectar spur of the flower, suggesting coevolution. [ 4 ] Hawk moths, including H. lineata , are considered long-tongued nectar foragers, although nearly 20% of all hawk moth species have very short tongues compared to H ...
Its long proboscis (25–28 mm (1.0–1.1 in)) [9] and its hovering behavior, accompanied by an audible humming noise, make it look remarkably like a hummingbird while feeding on flowers. Like hummingbirds, it feeds on flowers which have tube-shaped corollae. [9] It should not be confused with the moths called hummingbird moths in North America ...
The blue-chinned sapphire is 8.9 cm (3.5 in) long and weighs 3.8 g (1 ⁄ 8 oz). The bill is fairly straight, with the upper mandible black and the lower reddish. The male has mainly green plumage, darker above, with white thighs, a forked metallic blue tail and blue upper throat.
In one day, the bee hummingbird may visit 1,500 flowers. [6] It is a diurnal bird that can fly at 40–48 km/h (22–26 kn; 11–13 m/s), and it beats its wings 80–200 times per second, which allows it to remain stationary in the air to feed on flowers. The bee hummingbird lives up to seven years in the wild, and 10 years in captivity. [3]

Sunbird drinking nectar from typical bird-pollinated flower As nectar is a primary food source for sunbirds, they are important pollinators in African ecosystems. Sunbird-pollinated flowers are typically long, tubular, and red-to-orange in colour, showing convergent evolution with many hummingbird -pollinated flowers in the Americas. [ 10 ]
