Genera

The crow family Corvidae, are the largest birds of the Passeriformes. This group show themselves at the very least, to have a flexible approach to their food-finding and interaction between fellow species members, and with other animals. Some of the larger species (especially in the genus Corvus) also show levels of learned behavior of a high degree, and even insight in some examples that can be interpreted as intelligence.

There are many species in this family, but they can be divided into well-defined groups.

  • The Crows, genus Corvus, including Ravens

  • The Jays

  • The Choughs, genus Pyrrhocorax

  • The Magpies

  • The Treepies

  • The Nutcrackerss, genus Nucifraga

  • The Ground-jays, genus Podoces

  • Stresemann's Bush-Crow, Zavattariornis stresemanni

  • Piapiac, Ptilostomus afer


Hume's Ground Jay (Pseudopodoces humilis) has now been asigned to the Tit or Titmouse family (Paridae). See link below for latest details:

Mayo Clinic Researchers Develop New Treatment For Incurable Recurring
A study led by Mayo Clinic researchers and conducted by the North Central Cancer Treatment Group (NCCTG) reports that a new "smart"drug treatment for an incurable form of recurrent brain cancer slowed tumor growth in more than one-third of the 65 adult patients who tried it.
