Rufous-crowned Sparrow

Flourishing in the hot, sweltering heat of summertime, Rufous-crowned Sparrows are chunky little birds that tend to stay put in the areas they make their homes in. Blending into their surroundings, these birds tend to keep to themselves unless presented with a threat. Even then, these critters are not shy if left to their own devices, making it easy for a cautious and careful bird watcher to observe them in their natural habitat.

About Rufous-crowned Sparrows

Rufous-crowned Sparrows are a resident species, commonly found in hot, rocky, scrubby, and dry areas of southwestern Mexico and the United States, such as canyons, hillsides, and dry slopes. Due to this, they are classified as an American Sparrow. Despite being perfectly capable of flight, they prefer to walk and hop on the ground and aren’t afraid of the odd bird-watcher or two that may approach them to get a closer look, as long as they don’t feel threatened.

Their oddly endearing behavior has them stand out from other species of birds that exist, and make for quite an interesting observational experience for both beginner and experienced bird watchers alike. If you’d like to learn more about them in case you come across one, we’ve compiled a database of information regarding these quirky little birds,

Rufous-crowned Sparrow Color Pattern

Rufous-crowned Sparrows spot very neutrally colored plumages across sexes and ages, resulting in them blending a little too well into their surroundings. However, equipped with the right information and a just little persistence, spotting these birds shouldn’t prove to be too big of a task, even for newcomer bird watchers.

Rufous-crowned Sparrows sport foreheads and crown areas stained with a dusty brownish-reddish color, with their foreheads painted with a whitish stripe. The sides of their heads and neck are brown, their backs and shoulder areas grayish-brown. Their rump and upper-tail are brown, with the fringes of the upper-tail dusted in a grayish hue. White throats with a thin black stripe, white bellies, and grayish-brown breasts and sides are a common sight on these birds. Their tails are a very dark brown, with a fairy faint and darker shaded brown cross-bearings on the larger feathers. Interestingly enough, both sexes of Rufous-crowned Sparrows have little to no difference between their plumages.

Description and Identification

Rufous-crowned Sparrows have brown irises with legs that are a mix of a light yellowish-brown or shades of pale dusky pink. Sometimes; however, they simply appear to be a pale brownish shade, bordering a dull yellow. For immature birds of this species, their bills are a combination of gray and white, appearing very pale on the
saturation scale. Adults thought, lean towards dark brown or dark bluish shades. Some have even appeared to have dusky brown bills with a speck of pale yellow on the edges, or may altogether be a pinkish-gray. Their tails are quite long and rounded. Both sexes of this species have a very prominent white eye ring.

These birds are often confused with American Tree Sparrows due to their similar plumage identifiers such as their red-brown caps and solid-colored breasts. To avoid this confusion, it is important to note that Rufous-crowned Sparrows have a rounded tail, something that typical American Tree Sparrows do not have. 

Spotting Rufous-crowned Sparrows can be a slight challenge because they reside in densely covered areas. Due to their brave nature, once you spot them, you can observe them from close quarters, so long as they do not feel threatened and you do not disturb them. These little critters hop and walk along the ground, taking their time and moving slowly to scour the area.

Rufous-crowned Sparrow Song

The songs of Rufous-crowned Sparrows are mostly performed by the males of the species in a variety of situations, such as while perching in order to garner attention, or while taking flight during the breeding season. They partake in the attraction of mates and protect their territory from predators and other dangers.  Calls that are performed by these species are shared and delivered by both sexes of Rufous-crowned Sparrows as well as by all age groups, with no discrimination with regards to the time of the year they are performed in. They act as a sort of simple communication between individuals in this species. 

Their primary song and most commonly used one is a series of rapid, dispersed and mixed notes that considerably vary in terms of their pitches and durations, yet typically sporting a pattern of 5 to 11 syllables. They soung like a “chi-chi-chew, CHU, tsi-tsi-ti-tsi-ti, tweele”. The secondary song of Rufous-crowned Sparrows is quite similar to their primary song and is termed as a softer, gentle alternative to the latter, performed by males as they forage for food on the ground. When separated from their mates, they will make a hasty “dear-dear-dear” call.

Rufous-crowned Sparrow Size

Rufous-crowned Sparrows are smaller Sparrows, at around 5.9 inches to 6.3 inches in length. Generally, the males of this species are larger than the females. On average, they weigh anywhere between 0.6 pounds to 0.7 pounds.

Rufous-crowned Sparrow Behavior

Pairs of Rufous-crowned Sparrows are supported by their own territory, although studies of this unique species have shown that on certain occasions, individuals without a mate may possibly share territories with a mated pair. 

These birds are, in fact, quite awkward in flight, and resort to hopping and running around the ground as their most favored mode of transportation. They are extremely slow foragers and will forage with their respective mated pair during the breeding season, and in huge flocks around the late summer and early autumn seasons. 

Rufous-crowned Sparrows often fall victim to attacks from predators such as house cats and small raptor birds – even their nests do not pertain to be safe from mammal and reptile attacks. If you happen to observe one, you may notice them use one of the three kinds of distraction display they know in order to protect themselves and fend off their attackers. These being, the “rodent run”, the “broken wing”, and the “tumbling off the bush”. 

During the rodent run, Rufous-crowned Sparrows will lower their heads, necks, and tails, hold their wings out, and fluff their feathers as they discharge an alarm call. In the broken wing display, these birds will pretend to have broken their wings and lead the predator away from the nest before making their escape. For the last display, they attempt to distract the predator by falling from the top side of a nearby bush in order to confuse the predator.

Rufous-crowned Sparrow Diet

The diet of Rufous-crowned Sparrows mostly consists of a variety of insects and seeds. The contents of the diet have the possibility of variation during the different seasons. However, Rufous-crowned Sparrows consume more insects during the summer and increase their seed intake during the winter. The bugs they consume are different species of caterpillars, beetle larvae and adult beetles, ants, spiders, grasshoppers, scale insects, and more. The preferred seeds for their consumers tend to be variants of grasses and weeds.

They almost never forage in open areas, they restrain themselves to areas with dense vegetation, picking food from grasses and shrubs while accompanied by their mated pair or family. You can see them drinking and bathing in water pools after heavy rainstorms. 

Rufous-crowned Sparrow Habitat

The general region of the world that you can find a Rufous-crowned Sparrow is the southwestern United States and Mexico, in states such as California, Arizona, New Mexico, and Texas. They have also been seen in coastal scrublands and chaparral areas. They tend to reside in brushy, hot, and dry areas, that provide a lot of covers and surrounded by rocks. You can find almost always find them on grassy or rocky slopes with low bushes, or on oak and pine trees, hiding in thickets, while hanging around in small, isolated groups. 

Rufous-crowned Sparrows in California reside in steep, rocky slopes in shrubs and patches of different types of grass. Those in Texas habitate rocky, hilly and semi-open areas that are interspersed with oak and cedar trees, as well as clumps of grass. 

Range and Migration

One of the most unique characteristics of Rufous-crowned Sparrows in comparison to other bird species is that they do not display true migratory behavior. They are year-round residents to the place they habitat, making them easier to locate, without a migratory pattern to chart. 

Rufous-crowned Sparrow Lifecycle

If you peak into the nest of a Rufous-crowned Sparrow, you’ll most probably find anywhere between 2 to 5 eggs, which is the average size of their brood. In most regions, they raise only one brood a year; however, Rufous-crowned Sparrows in California raise 2 and sometimes even 3 broods a year. In the instance of a nesting failure, there is a chance for the female Sparrows to lay replacement eggs. The eggs are a pale, bluish-white color.

For a typical brood, incubation lasts from 11 to 13 days and only happens with the female Rufous-crowned Sparrows. As the hatchlings appear from the shell, they do not adorn any feathers until at least three days have passed. While only females of the species brood the nestlings, both the male and female parents will bring insects to feed their young. The nestlings will prematurely leave the next after around 8 days, despite not being able to fly. After graduating to juvenile age, they tend to leave the territory and find their own in a nearby habitat during the early winters. Reproduction tends to take place during periods of high rainfall, as snakes reduce their activity and movement, inadvertently serving as a means of protection for the birds. 

Nesting

Nests of Rufous-crowned Sparrows are mainly built using rootlets and coarse dried grasses, commonly found in the areas that they reside in. Twigs, pieces of bark, and weed stems may also be added to the constructional composition of the nest to provide it extra backing. They are shaped like open cups, thick-walled yet loosely constructed. These nests are located in low bushes or shrubs, situated close to the ground, yet hidden from prying eyes and most
predators. 

Anatomy of a Rufous-crowned Sparrow

Rufous-crowned Sparrows are typically small in size, equipped with rounded heads and relatively long and rounded tails. One thing to keep in mind is that the males of the species are larger than the females. These birds sport thick and pointy bills, almost conical in shape, and are fairly large in size. Their wings are short and rounded. 

Final Thoughts

Rufous-crowned Sparrows can be easily overlooked due to their plain appearance but in fact harness quite an interesting background and behavior pattern to themselves. Their lack of a migratory pattern and habit stands out as a very significant feature of theirs, one that is not very often seen with other bird species. 

Their unique mannerisms of walking and hopping along the ground as their preferred mode of transportation, in comparison to flying, is quite a sight to behold and may aid you in spotting these birds in the wild. They aren’t afraid of being approached, as long as they remain uninterrupted from their foraging and detect no signs of a threat to their being, allowing bird watchers to get a closer view of these Sparrows. 

Visitors of the southwestern United States and Mexico will easily be able to spot these tiny critters during scenic treks in rocky and vegetated areas. Their plumages may inadvertently camouflage them into their surroundings, but the extra effort to spot them is certainly worth it, to witness their mannerisms and daily chattering.
