Red-breasted Nuthatch
Sitta canadensis
The red-breasted nuthatch is a small passerine, measuring 4.5 in (11 cm) in length, with a wingspan of 8.5 in (22 cm) and a weight of 9.9 g (0.35 oz). Its back and uppertail are bluish, and its underparts are rust-coloured. It has a black cap and eye line and a white supercilium (eyebrow). Sexes are similarly plumaged, though adult males are brigher orange below, and conversely females and youngsters have duller heads and paler underparts. Voice: The red-breasted nuthatch's call is high-pitched, nasal and weak. Transcribed as yenk or ink, they have been likened to a toy tin horn or a child's noisemaker. Its song is a slowly repeated series of clear, nasal, rising notes, transcribed as eeen eeen eeen.

White-breasted Nuthatch
Sitta carolinensis
The white-breasted nuthatch is a medium-sized nuthatch, measuring about 15.5 cm (6.1 in) in length. Like other members of its genus, it has a large head, short tail, short wings, a powerful bill and strong feet; it is 13–14 cm (5.1–5.5 in) long, with a wingspan of 20–27 cm (7.9–10.6 in) and a weight of 18–30 g (0.63–1.06 oz). The adult male of the nominate subspecies, S. c. carolinensis, has pale blue-gray upperparts, a glossy black cap (crown of the head), and a black band on the upper back. Voice: Like other nuthatches, the white-breasted nuthatch is a noisy bird with a range of vocalizations. The male's mating song is a rapid nasal qui-qui-qui-qui-qui-qui-qui. The contact call between members of a pair, given most frequently in the fall and winter is a thin squeaky nit, uttered up to 30 times a minute.
