The caveat of these stars are that they are catalogued on this site. If you know of a star that is nearer or further then do let me know in the comments and I'll add it to the site. The stars mentioned are from the Hipparcos catalogue or have been added because of their special status.
Corvus was the crow of Apollo. Apollo wanted fresh water for a sacrifice to Zeus but the crow did not return in time. Corvus used a Crater to fetch the water in. The crow stopped to wait for some figs to ripen before he could eat. Corvus, fearing for his life, made up an alibi story with Hydra but Apollo didn't accept it. Corvus was punished that his throat would become sore when figs were ripening. It was turned to black from white as punishment and a warning to others. It was placed in the sky.
There are 3 Meteor Showers that occur during the year within this constellation based on information gathered from Adam Mickiewicz University (Poland). The ones listed as the ones I've been able to find a date range for. For others if you have the time, you can visit the AMU site, obtains the SL value then use IMO tables to calculate the date. A lot of the Meteor Showers are weak and you need to do a lot of stargazing to spot them.
