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.
While birds, including raptors, wading birds and roadrunners, and mammals are known to prey on reptiles, the major predator is other reptiles. Some reptiles eat reptile eggs, for example the diet of the Nile monitor includes crocodile eggs, and small reptiles are preyed upon by larger ones.
Bird-eating raptors also tend to show greater sexual dimorphism than other raptors, with the females being larger than the males. [ 2 ] Some avian avivores such as the shikra , besra , Eurasian sparrowhawk , and sharp-shinned hawk catch their prey by flying from cover in a tree or bush, taking their prey unawares.
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 ...
This diet stands in stark contrast with an iguana from the same genus, Ctenosaura similis. This animal's diet is composed of primarily fruit (73%) and leaves (25%), with no consumption of flowers. [6] The green iguana (Iguana iguana) has a similar diet to the spiny-tail iguana, with its diet composed of 52.1% leaves, 7.7% fruit, and 35.2% ...
Birds are, by far, the most diverse class in the red-tailed hawk's prey spectrum, with well over 200 species known in their foods. [66] [86] [87] In most circumstances where birds become the main food of red-tailed hawks, it is in response to ample local populations of galliforms. As these are meaty, mostly terrestrial birds which usually run ...
