Common Raven Corvus corax
Common Raven Corvus corax belongs to the largest songbirds in our region – at maturity, Common Ravens averages 50 cm in length and weighs about 1,5 kg. There were many of them during the medieval times but it fully disappeared in the 19th century. It reappeared as late as in 1968 when one pair of ravens nested in the ruins of Hukvaldy Castle and gradually began to spread again. The Common raven lives alone in permanent relationships for many years. It comes back to the nesting places at the end of February and begins to build or rebuild the old nest. Its nests are usually found in tall trees or inaccessible rocks. It nests in old vegetation around the Olza river and belongs to endangered species protected by law.
