The American robin rejects cowbird eggs, so brood parasitism by the brown-headed cowbird is rare, and the parasite's chick does not often survive to fledging. [41] In a study of 105 juvenile robins, 77.1% were infected with endoparasites, Syngamus sp. being the most commonly encountered, in 57.1% of the birds. [42]
An American robin (Turdus migratorius) feeding its chick a worm. Parental care refers to the level of investment provided by the mother and the father to ensure development and survival of their offspring. In most birds, parents invest profoundly in their offspring as a mutual effort, making a majority of them socially monogamous for the ...
Before and after social pairing and mating occurs, bird song is mainly dedicated to territorial defense. This behavior is a sexually selected trait because it ensures defense of the female who is rearing her offspring. [9] There is also some evidence that vocal amplitude effects male-male competition in such species as the great tit. Most ...
Mating is preceded by a courtship/pairing period in many animal mating systems. It is during this period that sexually mature animals select their partners for reproduction. [53] This courtship period, which involves displays to attract a mate by a member of a species, is usually short, lasting anywhere from 15 minutes to a few days.
Type A: An 'all-purpose territory' in which all activities occur, e.g. courtship, mating, nesting and foraging; Type B: A mating and nesting territory, not including most of the area used for foraging. Type C: A nesting territory which includes the nest plus a small area around it. Common in colonial waterbirds. Type D: A pairing and mating ...
The Australasian robin family was first introduced in 1888, as a subfamily with the spelling Petroecinae, by the English ornithologist Alfred Newton. [ 1 ] Although named after true robins , the Australian robins, along with many other insect-eating birds, were originally classified as flycatchers in a huge family Muscicapidae . [ 2 ]
The European robin (Erithacus rubecula), known simply as the robin or robin redbreast in the British Isles, is a small insectivorous passerine bird that belongs to the chat subfamily of the Old World flycatcher family. [3] It is found across Europe, east to Western Siberia and south to North Africa; it is sedentary in most of its range except ...
Like all Australian robins, the eastern yellow robin tends to inhabit fairly dark, shaded locations, and is a perch and pounce hunter, typically from a tree trunk, wire, or low branch. Its diet includes a wide range of small creatures, mostly insects. Breeding takes place in the spring and, as with many Australian birds, is often communal.
