The juniper titmouse (Baeolophus ridgwayi) is a passerine bird in the tit family Paridae. The American Ornithologists' Union split the plain titmouse into the oak titmouse and the juniper titmouse in 1996, due to distinct differences in song, preferred habitat, and genetic makeup. [2]
The juniper titmouse is a small, gray bird with small tuft or crest. Male and female are visually similar.
This titmouse lives year-round primarily in the Great Basin, but is resident from southeastern Oregon and central Colorado south to the eastern Mojave Desert in California and central Arizona, as far as west Texas and extreme northeastern Sonora, Mexico-(the Madrean sky islands). It prefers open woodlands of warm, dry pinyon-juniper, juniper and desert riparian woods.
Juniper titmice will sleep in cavities, dense foliage, or birdhouses. When roosting in foliage, the titmouse chooses a twig surrounded by dense foliage or an accumulation of dead pine needles, simulating a roost in a cavity. It forms pairs or small groups, but does not form large flocks. It may join mixed-species flocks after breeding season for foraging.
The juniper titmouse eats insects and spiders, sometimes seen catching insects in mid air. It also eats berries, acorns, and some seeds, sometimes hammering seeds against branches to open them. The bird forages on foliage, twigs, branches, trunks, and occasionally on the ground. Strong legs and feet allows it to hang upside down to forage. Juniper titmice visit feeders with suet, peanut butter, and seeds.
The song of the juniper titmouse is a rolling series of notes given on the same pitch. Its call sounds like a raspy tschick-adee.
This species builds its nest in a woodpecker hole, natural cavity, or nest box, lining it with grass, moss, mud, hair, feathers, and fur. It breeds from March into July, with peak activity in April and May, laying 3–9 eggs, usually 4–7. The female is the primary incubator, the process of which takes 14–16 days. Young are altricial, and are tended by both parents in nest for 16–21 days. Parents continue to tend to young for another three to four weeks after the young leave the nest.
The oak titmouse and juniper titmouse appear almost identical, but differ in voice as well as range. The oak titmouse has a browner back than the juniper titmouse. The oak titmouse gives a repeated series of three to seven syllables, each composed of one low and one high note, while the juniper titmouse song consists of a series of rapid syllables on the same note. Ranges overlap only in a small area in California. The tufted titmouse, which does not overlap in range, has whiter belly, rusty flanks, and black on the forehead.
The penduline tits constitute the family, Remizidae, of small passerine birds, related to the true tits. All but the verdin make elaborate bag nests hanging from trees, usually over water.
The tits, chickadees, and titmice constitute the Paridae, a large family of small passerine birds which occur mainly in the Northern Hemisphere and Africa. Most were formerly classified in the genus Parus.
The mountain bluebird is a migratory small thrush that is found in mountainous districts of western North America. It has a light underbelly and black eyes. Adult males have thin bills and are bright turquoise-blue and somewhat lighter underneath. Adult females have duller blue wings and tail, grey breast, grey crown, throat and back. In fresh fall plumage, the female's throat and breast are tinged with red-orange which is brownish near the flank, contrasting with white tail underparts. Their call is a thin 'few' while their song is a warbled high 'chur chur'. The mountain bluebird is the state bird of Idaho and Nevada. This bird is an omnivore and it can live 6 to 10 years in the wild. It eats spiders, grasshoppers, flies and other insects, and small fruits. The mountain bluebird is a relative of the eastern and western bluebirds.
The sittellas are a family, Neosittidae, of small passerine birds found only in Australasia. They resemble nuthatches, but whilst they were considered to be in that family for many years they are now afforded their own family. They do not migrate other than for local movements.
The rusty blackbird is a medium-sized New World blackbird, closely related to grackles. It is a bird that prefers wet forested areas, breeding in the boreal forest and muskeg across northern Canada, and migrating southeast to the United States during winter.
The white-breasted nuthatch is a species of bird in the nuthatch family Sittidae. It is a medium-sized nuthatch, measuring approximately 15.5 cm (6.1 in) in length. Coloration varies somewhat along the species' range, but the upperparts are light blue-gray, with a black crown and nape in males, while females have a dark gray crown. The underparts are whitish, with a reddish tinge on the lower abdomen. Despite not being closely related, the white-breasted nuthatch and the white wagtail are very similar in plumage. The white-breasted nuthatch is a noisy bird. It has a nasal voice and often utters little cries or vocalizations, often composed of repetitions of small invariant whistles. In summer, it is an exclusively insectivorous bird, consuming a wide range of arthropods, but in winter its diet consists mainly of seeds. The nest is located in the cavity of a tree. The clutch consists of five to nine eggs, incubated for two weeks by the female, who is fed by the male. The two adults then feed the young until they fledge, and for a few weeks after that.
The black-capped chickadee is a small, nonmigratory, North American songbird that lives in deciduous and mixed forests. It is a passerine bird in the tit family, the Paridae. It is the state bird of Massachusetts and Maine in the United States, and the provincial bird of New Brunswick in Canada. It is well known for its ability to lower its body temperature during cold winter nights, its good spatial memory to relocate the caches where it stores food, and its boldness near humans.
The Carolina chickadee is a small passerine bird in the tit family Paridae.
The tufted titmouse is a small songbird from North America, a species in the tit and chickadee family (Paridae). The black-crested titmouse, found from central and southern Texas southward, was included as a subspecies but now is considered a separate species, Baeolophus atricristatus.
The chestnut-collared longspur is a species of bird in the family Calcariidae. Like the other longspurs, it is a small ground-feeding bird that primarily eats seeds. It breeds in prairie habitats in Canada and the northern United States and winters to the south in the United States and Mexico.
Townsend's warbler is a small songbird of the New World warbler family.
The pygmy nuthatch is a tiny songbird, about 10 cm (4 in) long and about 10 grams in weight.
The mountain chickadee is a small songbird, a passerine bird in the tit family Paridae.
The oak titmouse is a passerine bird in the tit family Paridae. The American Ornithologists' Union split the plain titmouse into the oak titmouse and the juniper titmouse in 1996, due to distinct differences in song, preferred habitat, and genetic makeup.
The black-headed grosbeak is a medium-sized, seed-eating bird in the family Cardinalidae. It is sometimes considered conspecific with the rose-breasted grosbeak with which it hybridizes on the American Great Plains.
The Cape sparrow, or mossie, is a bird of the sparrow family Passeridae found in southern Africa. A medium-sized sparrow at 14–16 centimetres (5.5–6.3 in), it has distinctive plumage, including large pale head stripes in both sexes. Its plumage is mostly grey, brown, and chestnut, and the male has some bold black and white markings on its head and neck. The species inhabits semi-arid savannah, cultivated areas, and towns, and ranges from the central coast of Angola to eastern South Africa and Eswatini. Three subspecies are distinguished in different parts of its range.
The scaled quail, also commonly called blue quail or cottontop, is a species of the New World quail family. It is a bluish gray bird found in the arid regions of the Southwestern United States to Central Mexico. This species is an early offshoot of the genus Callipepla, diverging in the Pliocene.
The black-crested titmouse or Mexican titmouse, is a passerine bird in the tit family Paridae. Once considered a subspecies of the tufted titmouse, it was recognized as a separate species in 2002. It is native to southern Texas, Oklahoma, and east-central Mexico. Vagrants have been seen as far north and east as St. Louis, Missouri.
