While not all infected crows succumbed to WNV, American Crows and other corvids appear to be more differentially susceptible to death due to WNV than noncorvids (13-15).
Since 2000, surveillance for West Nile virus (WNV) in dead corvids has been the cornerstone of the early warning system for this virus in the Canadian public health system.
A potential implication of these findings, pending field trials using corvids and other species routinely collected as part of avian mortality surveillance, is that WNV may be detected by simply collecting swabs from carcasses and forwarding the swabs (frozen) to a virology laboratory for testing.
Testing confirmed H5N8 infection in a large proportion of sampled tufted ducks, Eurasian wigeons, gulls, raptors, and corvids (Table); another HPAI virus subtype was detected only twice (H5N5 in tufted duck and mute swan).
None of the positive corvids from the hunting bags had clinical signs, whereas 5 of 9 birds admitted to the veterinary clinic showed apathy, lameness, injuries, or fractures, which may not be associated with mycoplasmal infections.
Consistent with previous observational studies of magnetic alignment in free-roaming vertebrates, first- and second-order analyses show that corvids exhibit robust axial alignment corresponding with the north-south magnetic axis.
This consultation concerns the execution of mechanical removal of benefits caterpillar cocoons and removal and destruction of nests corvids for the city of Clermont-Ferrand.
He explains their sensory and perceptual processes, learning, spatial cognition and behavior, timing, numerical cognition, emotions, communication, and complex cognition about planning, social learning, and cognition about the minds of others, then provides case studies of honeybees, jumping spiders, cephalopods, corvids, parrots, dolphins, dogs, and great apes.
Genetic divergences and intraspecific variation in corvids of the genus Corvus (Aves: Passeriformes: Corvidae) - a first survey based on museum specimens.
From killing wildlife - including foxes, stoats, corvids and even protected birds of prey - to torching the precious peat uplands to encourage heather growth, shoot operators' every act is aimed at maximising the number of grouse to be shot.

The observations reported here, paired with those of Hoffmeister and Downes (1964), suggest that this opportunistic behavior could be exhibited by corvids in general.
During the early signs of spring here, you'll see swans pairing up on Bosherston Lakes, corvids building their nests - they're particularly fond of Stackpole Quay - and sap rising in woodland trees like sycamore and elder.
As each year's crop of spring lambs emerges, the temptation can be too much for cunning crows and clever corvids that, for the rest of the year, prefer the easy option of carrion and grain.
Corvids are large-brained birds, whereby the capacity for developing various social strategies (Emery and Clayton, 2004), exploiting a wide variety of food resources (Goodwin, 1986), and burying food, even during times of abundance (De Kort et al.
