Eastern chipmunk was one of the Natural sciences good articles, but it has been removed from the list. There are suggestions below for improving the article to meet the
good article criteria. Once these issues have been addressed, the article can be
renominated. Editors may also seek a reassessment of the decision if they believe there was a mistake.

The Eastern Chipmunk is territorial and does not tolerate others of its kind within several meters of its burrow. Fierce chases and biting to chase off encroaching individuals result when competing for food or mates. Males take no responsibility for the young beyond mating. Individual females live solitary except when nursing their young. They will drive off adolescent offspring when they become independent. Sometimes females will abandon a well stocked burrow after her young are weaned and establish a new home nearby. Young chipmunks will engage in play with one another while exploring the area immediate to their birth nest. Dominance for territory is established at this time with weaker individuals forced to move greater distances away. In areas where there are roads and traffic, young chipmunks often meet their demise under the wheels of motor vehicles. When food is abundant and predators scarce, the chipmunk can live to 5 years. They are alert, quick, and wary of danger, very industrious in food gathering, and bold once habituated to humans. Physically robust and agile, the adult chipmunk can leap vertically 10 times its body length. Chipmunks are fastidious in self grooming. They have no detectable odor and are visibly clean. A bird feeder near your window will attract chipmunks and allow hours of enjoyable observation.
was removed from
Chipmunk and placed here for consideration. Some duplication, but some citations would be nice to have prior to inclusion.

I'm unenthusiastic about some recent revisions: "solitary" is a widely used word and is clearer than "a loner". "Name origin" is little better than "etymology", and the section only deals with the word "chipmunk" anyhow. I'll probably make comments and minor improvements after Ucucha does. —

In the lead, it might be good to put it in a little more taxonomic context than just "rodent"—perhaps say it's a squirrel, and the only living member of the genus Tamias, one of three genera of chipmunks.
Could you add citations for the few parts of the description that don't have them?
The sentence about differences from Eutamias and Neotamias reads odd: "they differ by ... the penis bone". Is there some difference in the form of the baculum?
I don't like the "Biological statistics" table, especially in its current layout, as it is interrupting the flow of the article. There are also some problems within the table: neither a "diploid number" nor a "tooth formula" is clear to a nonspecialist. I would put it in the text and say "The eastern chipmunk has 38
chromosomes (2n = 38)." and "The
tooth formula is 1.0.1.31.0.1.3 × 2 = 20 (one
incisor, one
premolar, and three
molars on each side of both the upper and lower jaws)." Furthermore, the value for body mass under "Metabolism" is outside the range reported a few lines up.
You first say that the second breeding season in the year may involve young born during the first, but then that young will not breed during their first year.
I can't find this passage in the article. Where is it? The young would not be sexually mature during the spring and summer mating seasons of their birth year.

The louse Enderleinellus tamiasis may actually have come only from Eutamias sibiricus, it appears (Durden and Musser, 1994, Bull. Am. Mus. Nat. Hist. 218:13).
Whitaker and Hamilton? They may instead have missed it. Durden and Musser are online
here, if you wish to check it. I actually found another source
[1], from 1999, which definitively states the chipmunk E. tamiasis was first found on was misidentified. That's also consistent with the fact that the species has been found several more times on the Siberian chipmunk, but never on the eastern
[2].

I've just restored that section: why does a lack of stuff in the text on subspecies mean info on relations should be removed? —
innotata17:10, 3 July 2010 (UTC)reply
I'm not sure this complete enough even for GA grade, but I'll mostly leave that to Ucucha. Some comments for now, some beyond the GA criteria:
I modelled the article on those already passed to GA and thought I "covered all the bases" here (diet, habitat, predators, etc.). What have I neglected?

I don't think most current mammal featured and good articles are as complete as they should be. This article is certainly not anything like a featured article. But again, I'll leave this to Ucucha. —
innotata17:10, 3 July 2010 (UTC)reply
I don't think it's enough for an FA, but this is not an FA review and the standards for GAs are lower ("broad" instead of "comprehensive"). I think the current article is "broad". For a somewhat comparable FA,
marsh rice rat, I tracked down virtually all scientific literature on the species to search for relevant material. Whether all that is necessary for an FA, I'm not sure, but it is the direction to go.

"most formidable enemy is the
weasel": besides "enemy" being a bit problematic, weasels are a group of animals like hawks or foxes, not a species.

The eastern chipmunk (Tamias striatus) is a
chipmunk species native to eastern North America. Like other chipmunks, they transport food in pouches in their cheeks, as seen here. They eat bulbs, seeds, fruits, nuts, green plants, mushrooms, insects, worms, and bird eggs.Photo:

It is the sole living member of the chipmunk subgenus Tamias, sometimes recognised as a separate genus.
In fact the
Siberian chipmunk has been described as Eutamias sibiricus but also as Tamias sibiricus. Thus, the Eastern chipmunk shouldn't be defined as the sole living member of the chipmunk subgenus Tamias, even if stating immediately after that, sometimes recognised as a separate genus. The word sometimes doesn't allow to state is the sole living member. Is there or not any
scientific consensus about the Tamias genus? one or two species in Tamias?

Infobox image replacement?
The infobox image was replaced. To me, the replacement is obviously worse (doesn't show the whole animal, bad lighting, less detail...), but I don't want to revert myself because I took the replaced image. Bringing it up here instead. — Rhododendritestalk \\

Big Blue Cray(fish) Twins has been doing some excellent stuff around chipmunks and other :natural history articles but in this case agree the previous image was better for the :infobox. Alerting @

It's a great picture and I agree with your concerns. I made the change as it backs up the etymology of the Native American name, just to the left.
The eastern chipmunk (Tamias striatus) is a
chipmunk species found in eastern North America. It is a small species, reaching about 30 centimetres (12 in) in length, with a weight of 66 to 150 grams (2.3 to 5.3 oz). It has reddish-brown fur on its upper body and five dark brown stripes contrasting with light brown stripes along its back, ending in a dark tail. The eastern chipmunk can climb trees well, but constructs underground nests with extensive tunnel systems, often with several entrances. Its vocal repertoire consists of five sounds: the chip, the chuck, the trills, the whistle or squeal, and chatter. Trills have been measured to occur at the rate of 130 vibrations per minute. The eastern chipmunk lives a solitary life, except during courtship and mating and for the short period that young spend with their mothers after birth. It sometimes hibernates during the winter. This eastern chipmunk with stuffed cheeks was photographed in
Prospect Park in
Brooklyn, New York.
