Black-billed Magpie
Pica hudsonia
The black-billed magpie is an unmistakable bird within its range. It is a medium-sized bird that measures 45–60 cm (18–24 in) from tip to tail. It is largely black, with white scapulars, belly, and primaries, and the wings and tail are an iridescent blue-green. The tail is made up of long, layered feathers, the middle pair of which extend further than the rest. The beak is uniformly black, oblong, and weakly curved toward the tip. Adults also have black irises. Voice: The vocalizations of the black-billed magpie consist of a number of calls variously described as tweets, coos, purrs, shrills and squawks, but the most common is an alarm call, called a chatter, that is described as a ka-ka-ka-ka, sometimes preceded with a skah-skah. This call is very different from that of the Eurasian magpie, but is similar to that of the yellow-billed magpie.

Maghreb Magpie
Pica mauritanica
The Maghreb magpie is around 48 cm long, similar in plumage to the widespread Eurasian magpie, but with the distinct patch of vivid blue bare skin behind the eye and on the lower eye lid. The white patch on the scapular ('shoulder') feathers is smaller (though not as small as in the Asir magpie of Arabia), as is the white belly patch. The blue skin around the eye is not entirely unique, as it is also recorded occasionally in the Iberian subspecies of the Eurasian magpie Pica pica melanotos, particularly in southern Spain.
