Parus hudsonicus

The boreal chickadee (Poecile hudsonicus) is a small passerine songbird in the tit family Paridae. It is found in the boreal forests of Canada and the northern United States and remains within this range all year. [2] This bird is known for its high pitched trill patterns used in communication with other birds and food storage habits in preparation for winter months.

Description

Adults are 12.5–14.5 cm (4.9–5.7 in) long with a weight of 7–12.4 g (0.25–0.44 oz). They have grey-brown upperparts with a brown cap and greyish wings and tail; their face is mainly grey with white on the sides. Their underparts are white with brown on the flanks and a black throat. They have a short dark bill, short wings and a long notched tail. Their flight consists of brief gliding patterns followed by fast and bouncy wing beats as they travel through the air. [3]

Vocal communications

The call is a husky tsee-day-day, as well as a high pitched trill sound, dididididididi a variant on the call which gives chickadees their name. [3] This call is composed of five distinct note-type categories consisting of A, B, C, D and D-hybrid with the beginning and end note both displaying a high frequency pitch. [6] Boreal Chickadees use specialized notes within their vocal range to communicate with each other and convey information. [6] Certain notes/calls can be used as a mating tactic or to indicate a bird's rank to neighbouring fertile females in the area. [7] Females have also been known to be more attracted to a male chickadee if he portrays complex and larger song repertoires. [7] Calls can also be used in territory defence or to warn others of an invader that come to close to a nesting female. [7] Cross species comparisons can be made by comparing the vocal similarities between other species of chickadee's. [6]

Breeding/nesting behaviour

Their breeding habitat is coniferous woods in Canada, Alaska, and the northernmost portions of the contiguous United States. They generally breed from early May to the end of August and remain within their breeding range throughout the year, but sometimes move south in winter. [7] When a female chickadee finds a high quality male to mate with this provides direct and indirect benefits such as exceptional parental care and high quality genes. [7] The pair remains together year round and may mate for life. Winter movements south of their range, however, appear to have become increasingly rare. Large bodies of water and mountain ranges may restrict dispersal of the Boreal Chickadee into places such as the Vancouver Islands and Haida Gwaii. [8] They nest in a hole in a tree; the pair excavates the nest, using a natural cavity or sometimes an old woodpecker nest. This nest can be made of hair, fur or dead plants. [3] Five to seven eggs are laid, white with fine reddish-brown spotting. [4] Eggs are laid between May and July and hatch within 13–16 days. [7] After the eggs have hatched it takes another 16–18 days for the birds to fully develop wings large enough to attempt flight. [7]

Foraging behaviour

These birds forage on conifer branches or probe into the bark, gleaning insects and foraging for conifer seeds, which may be stored in preparation for winter months. [3] Boreal Chickadees are known to store large amounts of food in different trees, each location containing several food items. [9] Food is usually stored in the mid-region of trees at a lower level than at which they foraged. [9] They generally forage in black spruce, white spruce and tamarack trees which minimizes competition with Black-capped Chickadees who forage in more deciduous and mixed forests. [10] Boreal chickadees often forage in small flocks including other small birds, especially in winter.

Predators

With the advantage of being a winged bird the boreal chickadee has few predators. These consist of larger birds such as small owls, hawks and shrikes. [3] Predators of eggs and baby boreal chickadees generally consist of tree climbing animals such as squirrels, chipmunks, mice, bears and rats. [11]

Threats

The largest threat that is placed on boreal chickadees is clearcutting and logging that occurs in the boreal forest regions. [12] These practices are causing dramatic reductions in mature forests and rapidly modifying the habitat of boreal chickadees. [12]

Taxonomy

The species was formerly placed in the genus Parus with most other tits, but mtDNA cytochrome b sequence data and morphology suggest that separating Poecile more adequately expresses these birds' relationships. [13] Molecular phylogenetic studies have shown that the boreal chickadee is sister to the chestnut-backed chickadee (Poecile rufescens). [14] [15]

The ground tit, Tibetan ground-tit or Hume's ground-tit is a bird of the Tibetan plateau north of the Himalayas. The peculiar appearance confused ornithologists in the past who called it as Hume's groundpecker and still later as Hume's ground jay or Tibetan ground jay assuming that it belonged to the family Corvidae that includes the crows and jays. Although morphologically confusing, the species has since been identified using molecular sequence comparisons as being a member of the tit family (Paridae) and is the only species in the genus Pseudopodoces. It is found in the Tibetan Plateau of China, India, Nepal & Bhutan.

<span class="mw-page-title-main">Marsh tit</span> Species of bird

The marsh tit is a passerine bird in the tit family Paridae and genus Poecile, closely related to the willow tit, Père David's and Songar tits. It is a small bird, around 12 cm (4.7 in) long and weighing 12 g (0.42 oz), with a black crown and nape, pale cheeks, brown back and greyish-brown wings and tail. Between 8 and 11 subspecies are recognised. Its close resemblance to the willow tit can cause identification problems, especially in the United Kingdom where the local subspecies of the two are very similar: they were not recognised as separate species until 1897.

Until 2005 this species was lumped with numerous other subspecies. DNA studies have shown these other subspecies to be distinct from the great tit and these have now been separated as two distinct species, the cinereous tit of southern Asia, and the Japanese tit of East Asia. The great tit remains the most widespread species in the genus Parus.

<span class="mw-page-title-main">Sombre tit</span> Species of bird

The sombre tit is a member of the tit family found in southeast Europe and southwest Asia. Sombre tits occur in low density in thin woodlands at the elevation range between 1000 and 1600 metres above sea level. Similar to the other tit species, the sombre tit is a cavity-nesting species, which makes the nests in the holes in juniper, willow, poplar, and other relevant tree species. In some cases they nest in iron pipes, and in artificial nest-boxes. The clutch usually consists on 4 to 9 eggs, having two clutches per year. The species appear to be resident in the country with slight local movements. They breed on mountain slopes and in open deciduous forest; lower down on in trees and bushes in rocky terrain, as well as in fruit orchards. The breeding season lasts from early April till end of July - beginning of August. The food mainly consists on insects.

Poecile is a genus of birds in the tit family Paridae. It contains 15 species, which are scattered across North America, Europe and Asia; the North American species are the chickadees.

This is supported by mtDNA cytochrome b sequence analysis.
