Common Raven

Corvus corax

Summary ⁷

The Common Raven (Corvus corax), also known as the Northern Raven, is a large, all-black passerine bird. Found across the Northern Hemisphere, it is the most widely distributed of all corvids. There are at least eight subspecies with little variation in appearance—although recent research has demonstrated significant genetic differences among populations from various regions. It is one of the two largest corvids, alongside the Thick-billed Raven, and is possibly the heaviest passerine bird; at maturity, the...

Description of corvus corax ⁸

Raven 62 cm. De grootste kraai. Heeft zeer krachtige snavel, geheel zwart, glanzend verenkleed en verlengde keelveren, die ruig uiterlijk veroorzaken. Juveniel heeft bruinig, niet glanzend, zwart verenkleed. Altijd te onderscheiden van Zwarte Kraai door groot formaat, enorme snavel, \'ruige\' keel, wigvormige staart en geluid. Heeft krachtige vlucht met langzame vleugelslagen; zweeft vaak langdurig (andere kraaien niet) en haalt in de lucht acrobatische toeren uit, met name tijdens broedseizoen.

Justification

This species has an extremely large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence <20,000 km2 combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). The population trend appears to be increasing, and hence the species does not approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations). The population size is extremely large, and hence does not approach the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern.

One species at a time podcast: ravens ¹¹

We humans learn some of our earliest life lessons from our brothers and sisters, watching what toys our siblings play with and what treatsthey stash away for later. In this Halloween season podcast, Ari Daniel Shapiro journeys to Austria to learn how such social learning happens in a spooky bird—the raven.
