Herbivory is of extreme ecological importance and prevalence among insects.Perhaps one third (or 500,000) of all described species are herbivores. [4] Herbivorous insects are by far the most important animal pollinators, and constitute significant prey items for predatory animals, as well as acting as major parasites and predators of plants; parasitic species often induce the formation of galls.
The vast majority of parrots are, like this rose-ringed parakeet, cavity nesters. Only the monk parakeet and five species of lovebirds build nests in trees, [77] and three Australian and New Zealand ground parrots nest on the ground. All other parrots and cockatoos nest in cavities, either tree hollows or cavities dug into cliffs, banks, or the ...
[11] [20] The male and female have similar markings and plumage but, as with many birds of prey, the peregrine falcon displays marked sexual dimorphism in size, with the female measuring up to 30% larger than the male. [21] Males weigh 330 to 1,000 g (12–35 oz) and the noticeably larger females weigh 700 to 1,500 g (25–53 oz).
The budgerigar, or common parakeet (Melopsittacus undulatus), is a popular talking-bird species because of their potential for large vocabularies, ease of care and well-socialized demeanor. [27] Between 1954 and 1962, a budgerigar named Sparkie Williams held the record for having the largest vocabulary of a talking bird; at his death, he knew ...

It works to promote conservation and protection of birds and the wider environment through public awareness campaigns, petitions and through the operation of nature reserves throughout the United Kingdom.

The average size of the egg is 19.7 mm × 14.7 mm (0.78 in × 0.58 in). [16] [42] The eggs are incubated for an average of 11 days (range 10–16). Both adults incubate, although only the female stays on the nest at night. The chicks are altricial, hatching naked and with closed eyes, and are fed by both parents.
Unlike hummingbirds which lay only 2 eggs per clutch and can live up to a dozen years or more, kinglets are (together with some small quails) the most r-selected birds alive, with clutch sizes of around 10 eggs, a maximum lifespan of merely around 5 years even in captivity, and an annual mortality of 80%.
