Ravens do not hibernate during winter months in the traditional manner.  

This is a really complicated question to answer. Firstly, they’re good at remembering human faces. Studies show that if you treat them well, they’re more likely to trust humans. They’re also very intelligent, so it’ll be easier to gain their trust than other animals.

Ravens are often found to form groups. These bird flocks do come together for some very specific reasons, though. Raven groups are most common in the winter when these birds hunt together. Ravens form groups for a variety of other purposes as well, including protecting their area and their young ones.

Crows and ravens are not the same. The primary characteristics that distinguish these birds are their size and weight. For example, a common raven is about 60-68 centimeters long and weighs 1.2 kilograms, whereas an American crow can grow to be 40 to 50 centimeters long and weigh 300 to 600 gm.

You must first learn its basic characteristics. So, here is a list of all the characteristics of the raven, a fascinating all-black bird.

In the wild, ravens prefer to live in open spaces. Even so, if we had to name their habitat, it would be safe to say that ravens can be found in the wild in the following locations.
Mountains
Open forest
Coastal areas
Grasslands
Islands
Deserts 
Scrubby woodlands 
Open riverbanks
