Role of corvids
in epidemiology of West Nile virus in southern California.
Farmers say corvid
attacks on sheep peaked in 2013 when late snow weakened surviving lambs and carrion crows exacted a grim toll as they feasted on the eyes and tongues of ewes and their lambs.
since nest predation from corvids
tends to increase at edge habitats (Hannon and Cotterill, 1998), it would be reasonable to expect an increase in warbler nest predation by scrub-jays.
John Marzluff teams up with artist and fellow naturalist Tony Angell to provide an in-depth, detailed look at corvids
in general, considering crow behaviors, intelligence, actions, and even generosity in giving gifts to people who feed them.
tree squirrels, chipmunks, mice, kangaroo rats, spiny rats, some cavimorph rodents), most corvids
26), I have observed other corvids
that recognize a specific animal that has proven to be a threat.
Their lexicon only has 'on'y for the genus Corms and possibly for other corvids
Those reports distinguish at least diurnal raptors (Accipitriformes et Falconiformes), owls (Strigiformes), corvids
(Corvidae), and other predators, while many species determinations may be wrong (Martenson, 1908).
1998) and also with recent findings on free-living corvids
(Salomons et al.
Mark says: "Ravens, crows and other corvids
have a bad image and are thought of as black, menacing, horror film birds hanging round death scenes and graveyards.
OBJECTIVES: Our goals were to describe and quantify the spatial distribution of WNV infection in mosquitoes, humans, and corvids
, such as blue jays and American crows that are particularly susceptible to WNV infection, and to assess the relationship between WNV infection and proximity to CSO-affected streams in the city of Atlanta, Georgia.
Conway Morris cites experiments that show complex social organization and self consciousness as exemplified by mirror self recognition has evolved in Primates (Chimpanzees and Humans), Cetaceans (Porpoises and Killer Whales), and Corvids
(Crows, Jays, Magpies, etc.
Like other corvids
, such as crows, magpies are highly intelligent birds, they are even capable of recognising themselves in a mirror
Esther Woolfson has long been fascinated with corvids
, the bird family including crows, rooks, magpies and ravens.
Their topics include partition test and sexual motivation in male mice, gaze following in corvids
, current knowledge about the acoustic behavior of polar pinnipeds and emerging techniques for studying it, and constraints and the evolution of mutual ornamentation.
