Calonectris diomedea

The Cory's shearwater is a seabird of the eastern Atlantic Ocean. 
In Aristophanes' Birds the first part has two characters holding birds. In the English version, these are a crow and a jay. However, the word used in the original Greek seems to include multiple birds. κορώνη (koroni) may apply to the carrion crow, which carries today in its scientific name, Corvus corone. But the source suggests that it can be applied to the chough, a bird with a red bill and legs. That would be the red-billed chough, which also lives in Greece. The idea here seems to be that the red-billed chough is actually called a "sea crow", perhaps some people just called it crow for short? Additionally the website Perseus translates it from these sources and applies the word specifically to "Puffinus Kuhlii",http://www.perseus.tufts.edu/hopper/morph?l=korw%2Fnh%7C&la=greek&can=korw%2Fnh%7C0&prior=e)me\&d=Perseus:text:1999.01.0025:card=1&i=1 which seems to be an outdated name for the Cory's shearwater.https://marinespecies.org/aphia.php?p=taxdetails&id=1459991 Thus it's possible that the bird held in his hand in question isn't a crow, but rather a shearwater. It's a little big and it has webbed feet, but it can fit onto a hand or shoulder if it tried.https://www.youtube.com/watch?v=hcwGCRtqWtU Wiktionary thinks it applies to the Cory's shearwater and crow, but also applies it to nightingales.https://en.wiktionary.org/wiki/%CE%BA%CE%BF%CF%81%CF%8E%CE%BD%CE%B7 However, the proper name for nightingale in Ancient Greek is ἀηδών (aedon).https://en.wiktionary.org/wiki/%E1%BC%80%CE%B7%CE%B4%CF%8E%CE%BD#Ancient_Greek Whether it is actually supposed to be a carrion crow, a red-billed chough, or a Cory's shearwater is not known to me.
