Samples from carcasses of the family Corvidae
have been used in the surveillance for West Nile virus (WNV) since the virus was detected in the United States in 1999 (1).
Predominantly diurnal migration is relatively rare in passerines, having been documented in only a few families, including Corvidae
, Sturnidae, Hirundinidae, Fringillidae, and some Icteridae (Evans and Rosenberg 2000, Able 2001, Evans and O'Brien 2002).
Among these species, corvids may be of particular interest because several species of the family Corvidae
have experimentally been shown to be highly competent for WNV transmission (2,3).
These characteristics demonstrate the plasticity of this species in habitat use, similar to most species of Corvidae
However, many taxa do not have a natal down, including all Piciformes, many Psittaciformes, most Coraciiformes, and some Corvidae
(Jenni and Winkler 2004), and do not undergo a prejuvenal molt because the growth of juvenal plumage does not replace shed feathers.

The chough -also called the Red-leggedCrow in Welsh,or Fire-Crow as its scientific name translates -is of the Corvidae
family and is related to the Carrion Crow, theJackdaw and the Raven.
Pinon pine cones and seeds are constructed to promote seed harvest and dispersal by birds of the family Corvidae
([ILLUSTRATION FOR FIGURE 1 OMITTED]; Vander Wall & Balda, 1977).
Little is known about moose avoiding ticks in the environment or tolerance of moose to tick-foraging by magpies and other members of the Corvidae
as a strategy for tick removal.
A check of Ali's survey of the Corvidae
in his Handbook allows me to suggest that there is not really a problem of redundancy.

The early evolutionary history of the Corvidae
is poorly documented.
All homeowners and builders in Michigan should take note of these results," said Jacob Corvidae
, green programs manager, WARM Training Center, author of the report.
