Here is another magpie. This one’s easy - it’s obviously a Yellow-billed Magpie Pica nuttalli, which occurs only in California and which it seems everyone agrees is a distinct species. Yellow-billed Magpies have declined in recent years with 50% of the population reportedly killed by West Nile virus between 2004 and 2006.
Not all magpies are black and white birds with long tails! Below we have Red-billed Blue Magpie Urocissa erythrorhyncha from Asia, photographed in China and an Iberian Magpie Cyanopica cooki or perhaps an Azure-winged Magpie Cyanopica cyanus, photographed in Portugal. Whether you choose to call the latter an Iberian or an Azure-winged will depend on which taxonomy you’re inclined towards. We have blogged here on this subject in the past.
And not all black and white birds with a long tail are magpies! Below is a Magpie Shrike Urolestes melanoleucus, a fairly common bird in savanna-woodland in eastern and southern Africa. The photograph was taken in Tanzania. Presumably the English name was given to the bird by a 19th Century European explorer who saw some similarity to the plumage and shape of Pica pica.
