Corvids are large to very large [[passerine]]s with a robust build and strong legs; all species, except the [[pinyon jay]], have [[nostril]]s covered by bristle-like feathers.<ref name = Perrins/> Many corvids of temperate zones have mainly black or blue coloured [[plumage]]; however, some are pied black and white, some have a blue-purple iridescence, and many tropical species are brightly coloured. The sexes are very similar in color and size. Corvids have strong, stout bills and large wingspans. The family includes the largest members of the [[passerine]] order.

The smallest corvid is the [[dwarf jay]] (''Cyanolyca nanus''), at {{convert|41|g|oz|abbr=on}} and {{convert|21.5|cm|in|abbr=on}}. The largest corvids are the [[common raven]] (''Corvus corax'') and the [[thick-billed raven]] (''Corvus crassirostris''), both of which regularly exceed {{convert|1400|g|lb|abbr=off}} and {{convert|65|cm|in|abbr=on}}.

Species can be identified based on size, shape, and geography; however, some, especially the [[Australian crow]]s, are best identified by their raucous calls.<ref name = robertson2000 />
