The '''spotted towhee''' ('''''Pipilo maculatus''''') is a large [[American sparrow|New World sparrow]]. The taxonomy of the towhees has been debated in recent decades, and until 1995 this bird and the [[eastern towhee]] were considered a single species, the '''rufous-sided towhee'''.<ref name="r9" /> Another outdated name for the spotted towhee is the '''Oregon towhee''' (''Pipilo maculatus oregonus''). The call may be harsher and more varied than for the eastern towhee.

Individuals in the [[Socorro Island]] population are much smaller than other spotted towhees, and show distinctive gray upper-parts. That population is sometimes treated as a species: the '''Socorro towhee''' (''Pipilo socorroensis'').

==Description==
[[File:SpottedTowhee-24JAN2017.jpg|alt=Spotted Towhee female|thumb|left|224x224px|Female in [[Sacramento, California]].]] The spotted towhee is a large [[American sparrow|New World sparrow]], roughly the same size as a [[American Robin|robin]]. It has a long, dark, fan-shaped tail with white corners on the end. It has a round body (similar to [[American sparrow|New World sparrows]]) with bright red eyes and dull pink legs. The spotted towhee is between {{Convert|17|cm|in|abbr=on}} and {{Convert|21|cm|in|abbr=on}} long, and weighs in at between {{Convert|33|g|oz|abbr=on}} and {{Convert|49|g|oz|abbr=on}}.<ref name="r10"/> It has a wingspan of 11.0 in (28&nbsp;cm).<ref>{{Cite web|title=Spotted Towhee Identification |website=All About Birds |publisher=Cornell Lab of Ornithology|url=https://www.allaboutbirds.org/guide/Spotted_Towhee/id|access-date=2020-09-30|language=en}}</ref>

Adult males have a generally darker head, upper body and tail with a white belly, [[rufous]] sides, white spots on their back and white wing bars. Females look similar but are dark brown and grey instead of black. The spotted towhee has white spots on its primary and secondary feathers; the [[Eastern towhee]] is the same bird in terms of its size and structure but does not have white spots.<ref name="r10"/>

==Distribution and habitat==
The spotted towhee lives in dry [[Upland and lowland|upland]] forests,<ref name="r2" /> open forests, brushy fields, and chaparrals. It breeds across north-western [[North America]] and is present year-round in California, Nevada, Arizona, Utah, Oregon, Washington, Idaho and southern British Columbia.<ref name="r12" /> It is not found in arid climates and as a result does not reside in the [[Sonoran Desert]], but resides in northern Arizona and the entirety of California except the southeast corner that borders Arizona. It has also been known to expand as far eastward as western Iowa and southwestern Minnesota. It also occurs in fringe [[Wetland|wetland forests]] and [[Riparian zone|riparian forests]] near the border of upland forests.<ref name="r2" /> Because the spotted towhee's habitat overlaps with areas of the [[United States]] that experience regular forest fires ([[Arizona]], [[New Mexico]], [[California]]), it tends to be found in unburned [[chaparral]] and avoids chaparral and forests which have been burned<ref name="r6" /><ref name="r5" /> due to lack of ground cover and minimal foraging ability. Spotted towhees will be present in an area that is recovering after a burn (less than 15 years old),<ref name="r7" /> due to excellent ground cover and ease of ground foraging from the recovering understory vegetation,<ref name="r6" /> although populations will decrease after a forest fire until the vegetation has grown back.<ref name="r8" />
[[File:Spotted_Towhee_Sitting.jpg|thumb|Spotted towhee at Vasona Park]]
Its breeding habitat in the southwest is largely dependent on [[coastal sage scrub]], as it provides cover from predators.<ref name="r4" /> It migrates to northern and northwestern [[United States]] and southwestern [[Canada]] to breed in scrubland, parks and suburban gardens.<ref name="r12" /> Northwestern birds [[bird migration|migrate]] eastwards to the central [[plain]]s of the United States, mostly the northwestern-central [[Great Plains]]. In other areas, some birds may move to lower elevations in the winter. Their breeding [[habitat (ecology)|habitat]] is [[chaparral]], thickets or shrubby areas across western [[North America]]. This bird interbreeds with the [[collared towhee]] where their ranges overlap in southwestern [[Mexico]].

==Behavior==
===Breeding and nesting===
[[File:Pipilo_maculatus_in_Stanley_Park.jpg|thumb|left|Spotted towhees forage on the ground or in low vegetation.]] They nest either on the ground or low in bushes, seldom more than {{convert|1.5|m|ft|abbr=on}} above the ground<ref name="r1" /> and most nests are around {{convert|40|cm|ft|abbr=on}} above the ground.<ref name="r3" /> The location for the nests is usually found in exposed areas, but conceal the nest as it is being built.<ref name="r11"/> The female builds the nest over a period of about five days. It is bulky and sturdily made of leaves, strips of bark, twigs, [[forb]] stalks, and grasses, lined with pine needles, shredded [[Bark (botany)|bark]], grass, and sometimes hair. It is usually {{Convert|4.5|in|cm|abbr=on}} in diameter with an inner ring of {{Convert|2.5|in|cm|abbr=on}} to {{Convert|4|in|cm|abbr=on}}. The nests are built so the rim is at ground level and the nest is {{Convert|2.5|in|cm|abbr=on}} deep.

At least two [[Offspring|brood]]s, consisting of three to five eggs, are laid per season. The [[Bird egg|egg]] shells are grayish or creamy-white, sometimes with a tinge of green, with reddish brown spots that can form a wreath or cap. The eggs are slightly oblong, with their dimensions being {{Convert|2|cm|in|abbr=on}} to {{Convert|2.6|cm|in|abbr=on}} long and {{Convert|1.7|cm|in|abbr=on}} to {{Convert|1.9|cm|in|abbr=on}} wide. The female incubates the eggs alone for 12 to 14 days; the young leave the nest at 10 to 12 days. Nests are parasitized by cowbirds.

===Diet===
[[File:Spotted towhee gets anise swallowtail caterpillar.webm|thumb|A [[Pipilo maculatus|spotted towhee]] finds a [[Papilio zelicaon|anise swallowtail]] caterpillar to return to its nest and feed to its young.]]

These birds forage on the ground or in low vegetation,<ref name="r9" /><ref name="r11"/> with a habit of noisily rummaging through dry leaves searching for food. During the breeding season (spring and summer) they mainly eat [[insect]]s, ground dwelling beetles, [[spider]]s and other arthropods that reside in the [[leaf litter]] that is foraged by the spotted towhee. They only eat protein rich food in the breeding season, and in the fall and winter they focus on foraging for [[acorn]]s, [[seed]]s, oats, and [[Berry|berries]].<ref name="r11"/> They will frequent bird feeders if present in their woodland habitat.

===Threats===
Their main predators in less developed areas are [[Colubridae|ground dwelling snakes]] because nests are built on the ground. There is a strong relationship between the number of snakes that a nest encounters and the lowered probability of young chicks fledgling.<ref name="r4" /> In developed areas and habitat near urban development their main predators are household cats.<ref name="r11"/>
