Mexican Chickadee

Poecile sclateri

Tiny10 gForest

The Mexican chickadee is about 13 cm (5.1 in) long and weighs 9 to 12 g (0.32 to 0.42 oz). The sexes have the same plumage. Adults have a black head from the level of the eyes up and a black hindneck, both with a faint bluish gloss. The have pure black cheeks, chin, throat, and upper breast, and the rest of their face is white. The black on the chin and throat is conspicuously more extensive than on other chickadees, stretching onto the upper breast. Their back, scapulars, rump, and uppertail coverts are deep olive gray or mouse gray, with the strongest olive on the rump. Voice: The Mexican chickadee's song is "a series of short abrupt phrases peeta peeta peeta". Its principal calls are "a high buzzy sschleeeer" and "a high, buzzy, and hissing tzee tzee shhh shhh".

Sombre Tit

Poecile lugubris

Small16 gWoodland

The sombre tit is slightly smaller than a great tit (Parus major) with similar proportions, although in plumage it most resembles a willow tit (Poecile montanus) but it has a brownish to grey-black cap which extends further into the sides of the head with the off-white cheek patch being restricted to a narrow triangle by the larger bib. The head is often peaked when the bird is in an upright stance, unlike the willow tit. Compared to the sympatric marsh tit (P. palustris) the sombre tit has a proportionately longer tail. The juveniles are duller and tinged with brown than the adults.
