    CROWS:-Most crows are adaptable but often shy where persecuted; in towns, some become tame and may visit gardens. They all have strong, scaly feet, and stout (or downcurved) bills, mostly with a small patch of bristly feathers covering the nostrils. Northern populations of some species are migratory or nomadic, others are entirely resident.

    RAVEN:-The raven is a big black bird, a member of the crow family. It is massive, bigger than a buzzard. It is all black with a large bill, and long wings. In flight, it shows a diamond-shaped tail.

    ROOK:-Bare, greyish-white face, thinner beak and peaked head make it distinguishable from the carrion crow. Rooks are very sociable birds, and you're not likely to see one on its own

    Magpies seem to be jacks of all trades - scavengers, predators and pest-destroyers, their challenging, almost arrogant attitude has won them few friends

    Crows, rooks, and ravens are all perching birds (passerines) in the corvid family (family - Corvidae, subfamily - Corvinae, tribe - Corvini). The other members of this tribe are the jays, ground jays, magpies, treepies, jackdaws, and choughs.

    Crows and ravens are members of the subgenus Corvus. Madge and Burn list 45 species. Crows are smaller, sleeker, more omnivorous, and tend to have rectangular-shaped tails. Ravens have wedge-shaped tails, heavier builds, highly carnivorous diets, and more prominent throat hackles (long, thin feathers on the throat, raised in display). Many are locally common, but a few island species, like the Hawaiian crow or Alala, are highly endangered.

    Ravens are the largest perching birds, with the thick-billed raven of Ethiopia reaching 64 cm and 1500 g.

    Rooks are a species of crow (Corvus frugilegus) widely distributed in Europe and Asia. They're distinguished from other crows by a pale, bare patch at the base of the bill and front of the face. Adults run about run around 47 cm and have weighed in at 337 to 531 g. For comparison, a Eurasian crow (Corvus corone) runs around 48-56 cm and 399 to 602 g, while the American crow (Corvus brachyrhynchos) runs 39-49 cm and an average of 438 to 458 g.

    Rook: Around the size of trhe crow, if not a little smaller, they are similar to the crow in shape and behavior, but you can tell that it is a rook if the beak is more pointed, and white, distinguishing from the black, unlike the common reaven or the american crow

    Raven: well, there are a few kinds, but the one you are probably thinking about is the common raven. They are bigger, and they have a pointed tail. Also, they will glide, flap, then glide, like a halk, unlike an american crow

    Crow: They are smaller then the Raven, And they have a fanned tail. Tey are much more nonchelant in flight, but have a continuuos flap, sometimes with exeption when they are near their winter roos

    Crows are definately smallest. Many many many people have trouble in telling the difference between these birds in the wild. Ravens are the largest. I'm a birdwatcher in New England and am not that knowledgable on Rooks, but on Crows and Ravens, I know a few things.

    Ravens are large, all black and make a deep gutteral Grrrawwwk noise. Crows are smaller, not always with orange feet and beaks as some think, and make the classic Caw! noise. You're more likely to find huge flocks of crows with about 20 birds. Ravens live in family groups of about 2-6 birds.
