Oligophagy is a term for intermediate degrees of selectivity, referring to animals that eat a relatively small range of foods, either because of preference or necessity. [2] Another classification refers to the specific food animals specialize in eating, such as: Carnivore: the eating of animals Araneophagy: eating spiders; Avivore: eating birds
Ophiophagy (Greek: ὄφις + φαγία, lit. ' snake eating ') is a specialized form of feeding or alimentary behavior of animals which hunt and eat snakes.There are ophiophagous mammals (such as the skunks and the mongooses), birds (such as snake eagles, the secretarybird, and some hawks), lizards (such as the common collared lizard), and even other snakes, such as the Central and South ...
A crocodile needs from a tenth to a fifth of the food necessary for a lion of the same weight and can live half a year without eating. [80] Lower food requirements and adaptive metabolisms allow reptiles to dominate the animal life in regions where net calorie availability is too low to sustain large-bodied mammals and birds.
In general, reptiles become relatively common only in the diet in larger juvenile specimens and subadults. Large reptiles, or armoured reptiles such as turtles, were almost negligible in crocodiles under 2.5 m (8 ft 2 in) and most common in the stomachs of crocodiles over 3.5 m (11 ft 6 in) in length from Uganda and Zambia. Small species of ...
The Goliath birdeater (Theraphosa blondi) is reputed to be an avivore (hence the name), but it rarely preys on birds. [5] [6] However, other species of spider have been observed to consume birds that they capture; large orb-weaving spiders, such as the golden orbweavers, have been observed to consume small birds such as mannikin and other finches.
The diet in North America is particularly skewed towards mammals with roughly 84% of prey items being mammalian. [38] After mammals, other birds were most significant, comprising about 26.8% of prey. [10] Reptiles comprised about 7% of prey from across the range, with other prey groups comprising the remaining 3%. [10]
The Global Forum on Food Security and Nutrition suggests edible insects as a solution to the “rising costs of animal protein, food and feed insecurity, environmental pressures, population growth ...
Commercial bird food is widely available for feeding wild and domesticated birds, in the forms of both seed combinations and pellets. [9] [10]When feeding wild birds, the Royal Society for the Protection of Birds (RSPB) [11] suggests that it be done year-round, with different mixes of nutrients being offered each season.
