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]
Because of high mortality in the first year of life, a robin has an average life expectancy of 1.1 years; however, once past its first year, life expectancy increases. One robin has been recorded as reaching 19 years of age. [39] A spell of very low temperatures in winter can, however, result in higher mortality rates. [40]
The jacky winter (Microeca fascinans) is a small grey-brown robin found commonly throughout Australia and also in Papua New Guinea. The jacky winter acquired its name due to rapid and strong vocalisations, which sound like jacky-jacky winter-winter. [2] Their call is also often referred to as sounding like peter-peter-peter. [3]
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.
The red-capped robin (Petroica goodenovii) is a small passerine bird native to Australia. Found in drier regions across much of the continent, it inhabits scrub and open woodland. Like many brightly coloured robins of the family Petroicidae, it is sexually dimorphic. Measuring 10.5–12.5 cm (4.1–4.9 in) in length, the robin has a small, thin ...
The South Island robin is a small passerine, 10–18 cm in length and weighing around 35 g. North Island robins do resemble both females and juveniles of the South Island robins, as well as all the Stewart Island robins, which can sometimes make it difficult to distinguish between the three.
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 Japanese robin, along with the Ryukyu robin, can be traced back to 1835 when they were placed into one of the Coenraad Jacob Temminck's works under the name Erithacus akahige. After the 2006 molecular phylogenetic study, the species was placed into a clade under Larvivora , meaning "caterpillar eater," giving it half of its current ...
