This bird lives in upland regions, usually between 1,800 and 2,300 metres (5,900 and 7,500 ft) and can be found associated with wooded hillsides and forest edges, clearings, plantations, and gardens. Its diet consists mainly of honeybees although it also eat moths, butterflies, dragonflies, beetles, and other flying insects.
Out of 227 moths they released, 154 were carbonaria, 64 typica, and 9 insularia. The recapture rate within two days was 82%, 16%, and 2% respectively. It was another success, with Tinbergen capturing live movie clips of birds eating the moths. [2] [4]
The hummingbird hawk-moth (Macroglossum stellatarum) is a species of hawk moth found across temperate regions of Eurasia. The species is named for its similarity to hummingbirds , as they feed on the nectar of tube-shaped flowers using their long proboscis while hovering in the air; this resemblance is an example of convergent evolution .
The average bird meal consisted of 90.8% honey bees and 9.2% beetles. [28] Predation is more likely when the bees are queening or during the peak of migration, from late March till mid-April, and in mid-September. Hives close to or under trees or overhead cables are at increased risk as the birds pounce on flying insects from these perches. [29]
Hyles lineata, also known as the white-lined sphinx, is a moth of the family Sphingidae. They are sometimes known as a "hummingbird moth" because of their bird-like size (2-3 inch wingspan) and flight patterns. [2] As caterpillars, they have a wide range of color phenotypes but show consistent adult coloration. [3]
For a lone potoo, or a brooding adult with a potential predator close to the nest, the bird attempts to avoid detection by remaining motionless and relying on camouflage. If ineffective, the potoo breaks cover and attempts to intimidate the predator by opening its beak and eyes wide open while vocalizing or simply flies out of reach.
Sightings of the white-lined sphinx moth — Hyles lineata in scientific terms — have been reported "all over" Point Reyes National Seashore north of San Francisco.
Australasian figbird, catching a beetle on the wing. Hawking is a feeding strategy in birds involving catching flying insects in the air. The term usually refers to a technique of sallying out from a perch to snatch an insect and then returning to the same or a different perch, though it also applies to birds that spend almost their entire lives on the wing.
