Cottontail rabbit

<h2 id="etymology">Etymology</h2> <p>The <a href="/facts/Genus/m8EFjSms">generic</a> name <i>Sylvilagus</i> is derived from Latin <i>sylva</i> (woods) and <i>lagus</i> (hare), together meaning "hare of the woods".<a class="footnote-ref" id="fnref:6" href="#fn:6"><sup>6</sup></a> </p> <h2 id="evolution">Evolution</h2> <p>Cottontails are one of several species of <i>Sylvilagus</i>. Their closest relative is <i><a href="/facts/Brachylagus/hakAqaGX">Brachylagus</a></i>, the pygmy rabbit. They are more distantly related to the <a href="/facts/European_rabbit/fPkGSd2x">European</a> and other rabbits, and more distantly still to the <a href="/facts/Lepus/a3Pg06T3">hares</a>.

Almost every living <a href="/facts/Carnivorous/q6h6aSqe">carnivorous</a> creature comparable to or larger in size than these <a href="/facts/Lagomorph/0J5JT196">lagomorphs</a> is a potential predator, including such diverse creatures as domestic dogs, cats, humans, <a href="/facts/Snakes/YhA2gcn0">snakes</a>, <a href="/facts/Coyotes/RXpwhVfb">coyotes</a>, <a href="/facts/Mountain_lions/bIzW7fPk">mountain lions</a>, <a href="/facts/Foxes/0oeJleEN">foxes</a>, and if the cottontail is showing signs of illness, even <a href="/facts/Squirrel/yLLl7JWY">squirrels</a>. The cottontail's most frequent predators are various <a href="/facts/Birds_of_prey/AAfSeYT3">birds of prey</a>. Cottontails can also be parasitized by botfly species including <i><a href="/facts/Cuterebra_fontinella/3U7S34Ag">Cuterebra fontinella</a></i>.<a class="footnote-ref" id="fnref:10" href="#fn:10"><sup>10</sup></a> Newborn cottontails are particularly vulnerable to these attacks. Cottontails use burrows vacated by other animals, and the burrows are used for long enough periods that predators can learn where the cottontails reside and repeatedly return to prey on them. Though cottontails are prolific animals that can have multiple litters in a year, few of the resulting offspring survive to adulthood. Those that do survive grow very quickly and are full grown adults at three months.<a class="footnote-ref" id="fnref:11" href="#fn:11"><sup>11</sup></a> </p> <h2 id="eating-mechanics">Eating mechanics</h2> <p>In contrast to <a href="/facts/Rodent/mT4m8QJq">rodents</a>, which generally sit on their hind legs and hold food with their front paws while feeding, cottontail rabbits eat while on all fours. Cottontail rabbits typically use their nose only to move and adjust the position of the food that it places directly in front of its front paws on the ground. The cottontail will turn the food with its nose to find the cleanest part of the vegetation (free of sand and inedible parts) to begin its meal. The only time a cottontail uses its front paws while feeding is when vegetation is above its head on a living plant, at which point the cottontail will lift its paw to bend the branch to bring the food within reach.<a class="footnote-ref" id="fnref:12" href="#fn:12"><sup>12</sup></a> </p><p>Cottontails are rarely found foraging for food on windy days, because the wind interferes with their hearing capabilities. Hearing an incoming predator before they get close enough to attack is their primary defense mechanism.<a class="footnote-ref" id="fnref:13" href="#fn:13"><sup>13</sup></a> </p> <h2 id="species">Species</h2> <p>The subgenera were described in the 19th century based on limited morphological data that have been shown to not be of great use, nor to depict phylogenetic relationships. Molecular studies (limited in scope to the mitochondrial 12S gene) have shown that the currently accepted subgeneric structure,<a class="footnote-ref" id="fnref:14" href="#fn:14"><sup>14</sup></a> while of some heuristic value, is unlikely to withstand additional scrutiny.<a class="footnote-ref" id="fnref:15" href="#fn:15"><sup>15</sup></a> </p> <table><tbody><tr><th>Subgenus</th><th>Image</th><th>Common name</th><th>Scientific name</th><th>Distribution</th></tr><tr><th><i>Microlagus</i></th><td></td><td><a href="/facts/Brush_rabbit/P7gavP1e">Brush rabbit</a></td><td><i>Sylvilagus bachmani</i></td><td>West coast of North America, from the Columbia River in Oregon to the southern tip of the Baja California Peninsula.
