Should the Jay (Garrulus Glandarius) be re-classified within the Turdus (Blackbird+Thrush) Genus?

The eurasian jay would be classified as a corvid because in evolutionary terms, it has a much more recent common ancestor with other crows than it does with the thrushes.\n\nAny observed behavioural similarities would be an example of convergent evolution, similar to comparing old world vultures, which are related to birds of prey and new world vultures, which are more closely related to storks.\n\nPersonally, I think of the jay as behaviourally more like a shy version of the magpie (also a corvid), than a thrush.  E.g. both jays and magpies are nest robbers, preying on the young of other birds.

Carduelis is not a species, but a genus of the family of birds called finches or Fringillidae.  It  includes the greenfinches, redpolls, goldfinches, linnets, the twite and the non-African siskins.The wild canary (serinus canarie) and the red-fronted serin (serinus pusillus) both belong to the genus Serinus - also in the finch family Fringillidae. It includes the canaries, seedeaters and the African siskins.  So, I would say that the serinus pusillus is closest (genetically-speaking) to the canary (serinus canarie.)

The Javanese is a longhaired version of the Colorpoint Shorthair in CFA. In Europe, it is an obsolete term for the longhaired version of the Oriental Shorthair. All lesser cats are known as felis cattus.  As far as the cockatoos goes, you were somewhat nonspecific.  Note: Kingdom: Animalia <-->Phylum: Chordata<-->Class: Aves<-->Order: Psittaciformes<-->Family: Cacatuidae\nand the cockatoo then falls into many subfamilies(Microglossinae, Calyptorhynchinae and Cacatuinae,) genus and subgenus.  Please look up these to find your specific bird.  The gray squirrel is called Scurius niger and the fox (or red) squirrel is called Scurius carolinensis.  The goldfish is scientifically called Carassius auratus and the Southern black racer is called Coluber constrictor priapus whereas teh Northern Black Racer is called Coluber constrictor constrictor.  I hope this helps.

I think the word YET needs to enter your train of thought. 10 years ago there was no evidence to suggest that the Archaeopteryx wasn't the ancestor of all birds, now we know more and find that there is something that pre-dates it. In 20 years time there might well be eveidence to pre-date it yet further.\n\nWho knows what will turn up? Do you think this find discredits the theory of evolution or is it just the established theory of the evolution of birds that, until more evidence is discovered, has been undermined?

The biological species concept would call them, two species, if they did not interbreed. A geneticists may disagree on the grounds of lack of great genetic variation. A species and a variant are the same thing, for practical purposes, which makes it tricky. We do not draw typological lines in the sand, anymore, I think genetic methods will win out, but as a biologist, I go with the biological species concept. Read, Richard Dawkins and Ernst Mayr for opposite views on the subject.

heres a site  or 2 for you  to look at  about WOMAS AND BLACK-HEADED PYTHONS\nGENUS ASPIDITES PETERS 1876 \nAspidites is a genus of large terrestrial Pythons endemic to continental Australia. These pythons are readily distinguished from all other Australian species by the absence of pits on the labial or rostral scales. Other diagnostic traits are the absence of teeth on the premaxilla and enlarged symmetrical shields on the top of the head. Prior to now, most authorities have divided the genus into two well-defined species. These are the Black-headed Python (Aspidites melanocephalus) and the Woma (A. ramsayi). \n\nThe former is separated from the latter by its distinct glossy black head. At best the latter only has black markings on the head. Few authors recognize subspecies or races. Those that have subdivided the above species into races or regional variants, include Barker and Barker (1994a) and Wells and Wellington (1985a). The former recognized different races without naming them, while the latter recognized A. collaris as described by Longman in 1913 (see below). Taxonomy of this genus has gained greater interest in recent years with the introduction of more formalized reptile-keeper licensing systems in most Australian states combined with the high prices of specimens traded. Authorities in some states have taken a strong stand against hybridization of races of snakes, a view shared by a substantial number of private keepers. \n\nNoting that distinct differences between races of Aspidites are well known and acknowledged and that for many years a substantial number of herpetologists have recognized different races as being at least different subspecies, it is somewhat surprising that up until now no one has put names to these different races. Black-headed Pythons and Womas are known to occur sympatrically in parts of Western Australia, with this author catching both species on the western edge of the Great Sandy Desert, north of Port Hedland, WA.

I just tested that theory. I put my two parakeets in a pop tart box and threw a big stone at it. It works!!!!! They are both dead. Now I'm sorry I did it. They were nice birds and I miss them. Especially Jake. He could recite the Gettysburg address.

This will blow your teacher away!\n\nENGLISH HOUSE SPARROWS once found in huge numbers just a few years ago are now almost never seen and no one knows why!\n\n(fact!)

Probably great-tailed grackles. They're like huge blackbirds, very noisy and aggressive. Here's a photo and a link to their distribution map. I usually see them when I'm in Arizona in the spring.

Segregate two populations of creatures into separate environments, and see if evolutionary differences between the two populations occur over many generations. That's the sort of experiment the bible thumpers would have to twist logic into a pretzel in order to refute.

It looks that the answer is... YES!\nIt's a bird called JERDON'S COURSER [Rhinoptilus bitorquatus], an endangered species, one of the fifty rarest birds of the world. It is a rare and local endemic to the Eastern Ghats of Andhra Pradesh and extreme southern Madhya Pradesh, India, with a population estimated at 50-250 individuals.

Not around here they aren't. I haven't heard any evidence to say they are, but it is possible. Not very likely however. I would say it is more likely that they are disapearing from a specific place, such as around you, because of changes in the climate, introducion of a new species that is competeing with or eating the bees, or something like that.

No, Robin is the common name for a number of songbirds, notably the American robin, Turdus migratorius, and the European robin, Erithacus rubecula, in the thrush family, Turdidae. American colonists named the medium-size (25 cm/10 in), slate-backed, russet-breasted bird they found abundant in their new land for the much smaller (14 cm/5 in), friendly robin so popular in Europe, which has a brown back and orange breast. Depending on the severity of the local winter, the robin is either a resident or a migrant. Several other thrushes and some Old World flycatchers (family Muscicapidae) also are called robins.

The thrushes as a group are known for their complex double songs. All birds are theoretically capable of singing chords of a sort, or producing 2 sounds at once, because their syrinx is placed below the tracheal branching.\n\nSee for example

The goal behind DNA barcoding is that anyone, regardless of training can obtain an organism in the field, sequence DNA, and identify it to species.  This would be done by building a database with almost every species ever described in it.\n\nMost traditional morphologists would not mind the creation of such a database in theory, but oppose it as impractical.  The cost will be quite daunting and will almost certainly draw from funds that could go to traditional studies (including genetic studies conducted in an evolutionary framework).  The ability of this section of gene (CO1) to universally distinguish species has been questioned.  The universality of primers has also been questioned.  The main fear is that it will be perceived as a replacement for traditional taxonomy.  Genetic distance is a very crude approximation of species' splits at best, and a meaningless distraction at worst.

You would think that the pecking itself or the usage pattern of (as it were) of the pecker would be enough to identify not only the sub-species but the individual, however, there is not scientific evidence to show that this is the case. \n\nIt is possible through the use of photgraphs of the peckers to identfy even beyond the sub-species to the invidual (there are a few famous cases of this).
