The Northern Kites Project was responsible for the re-introduction of 94 young red kites in the Lower Derwent Valley between 2004 and 2009. In 2006 red kites began to breed in the region for the first time after an absence of over 170 years. Fifteen years later, the red kites are faring well in the core area but threats, like persecution, are preventing them from expanding their range. As mainly scavengers, the red kites are no risk to anyone or anything. However, since 2010, seven red kites have been found poisoned or shot near the Derwent Gorge and surrounding area. Sadly, there will have been many more undetected casualties.
