Amphibians are ectothermic, tetrapod vertebrates of the class Amphibia.
Clutch size refers to the number of eggs laid in a single brood by a nesting pair of birds.
Birds, also known as Aves, are a group of endothermic vertebrates, characterised by feathers, toothless beaked jaws, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a strong yet lightweight skeleton.
The California condor (Gymnogyps californianus) is a New World vulture, the largest North American land bird.
The common moorhen (Gallinula chloropus) (also known as the waterhen and as the swamp chicken) is a bird species in the family Rallidae.
The common starling (Sturnus vulgaris), also known as the European starling, or in the British Isles just the starling, is a medium-sized passerine bird in the starling family, Sturnidae.
David Lambert Lack FRS (16 July 1910 – 12 March 1973) was a British evolutionary biologist who made contributions to ornithology, ecology and ethology.
Desmognathus fuscus is a species of amphibian in the family Plethodontidae (lungless salamanders. The species is commonly called the dusky salamander or northern dusky salamander to distinguish it from populations in the southern United States which form a separate species, the southern dusky salamander (D. auriculatus). The northern dusky salamander is the most widespread representative of its genus in Canada. It can be found in eastern North America from extreme eastern Canada in New Brunswick south into the panhandle of Florida and west to Louisiana. The size of the species' total population is unknown, but is assumed to easily exceed 100,000. The species' habitat differs somewhat geographically; dusky salamanders in the northern part of the range prefer rocky woodland streams, seepages, and springs, while those in the south favor floodplains, sloughs, and muddy places along upland streams. They are most common where water is running or trickling. They hide under various objects, such as leaves or rocks, either in or near water. Alternatively, they may enter burrows for protection. The dusky salamander lays its eggs close to water under moss or rocks, in logs, or in stream-bank cavities. The larval stage which follows is normally aquatic.
An egg is the organic vessel containing the zygote in which an animal embryo develops until it can survive on its own; at which point the animal hatches.
The European goldfinch or goldfinch (Carduelis carduelis), is a small passerine bird in the finch family that is native to Europe, North Africa and western Asia.
Feral pigeons (Columba livia domestica), also called city doves, city pigeons, or street pigeons' Nagy, Kelsi, and Johnson, Phillip David.
A genus (genera) is a taxonomic rank used in the biological classification of living and fossil organisms, as well as viruses, in biology.
The great black-backed gull (Larus marinus), mistakenly called greater black-backed gull by some, is the largest member of the gull family.
In ecology, a habitat is the type of natural environment in which a particular species of organism lives.
Ibis, subtitled the International Journal of Avian Science, is the peer-reviewed scientific journal of the British Ornithologists' Union.
The lesser spotted eagle (Clanga pomarina) is a large Eastern European bird of prey.
The mallard (Anas platyrhynchos) is a dabbling duck that breeds throughout the temperate and subtropical Americas, Eurasia, and North Africa and has been introduced to New Zealand, Australia, Peru, Brazil, Uruguay, Argentina, Chile, Colombia, the Falkland Islands, and South Africa.
The masked lapwing (Vanellus miles), also known as the masked plover and often called the spur-winged plover or just plover in its native range, is a large, common and conspicuous bird native to Australia, particularly the northern and eastern parts of the continent, New Zealand and New Guinea.
A nest is a structure built by certain animals to hold eggs, offspring, and, occasionally, the animal itself.
Oology (or oölogy) is a branch of ornithology studying bird eggs, nests and breeding behaviour.
Parent–offspring conflict (POC) is an expression coined in 1974 by Robert Trivers.
Predation is a biological interaction where a predator (a hunting animal) kills and eats its prey (the organism that is attacked).
In ecology, r/K selection theory relates to the selection of combinations of traits in an organism that trade off between quantity and quality of offspring.
Reptiles are tetrapod animals in the class Reptilia, comprising today's turtles, crocodilians, snakes, amphisbaenians, lizards, tuatara, and their extinct relatives.
In biology, a species is the basic unit of classification and a taxonomic rank, as well as a unit of biodiversity, but it has proven difficult to find a satisfactory definition.
Among animals, viviparity is development of the embryo inside the body of the parent, eventually leading to live birth, as opposed to reproduction by laying eggs that complete their incubation outside the parental body.
