I would imagine that most of these sightings relate to birds from the continent as there have always been March/April records in Essex.

Thanks Phil - I'm sure that you're right about the continental origin of these birds. Looking back in the Essex Bird Reports for Red Kites reports in April/May (which tend to be the months with the greatest totals) there were: 26 in 2008; 24 in 2007, 29 in 2006; 23 in 2005; 15 in 2004; and 9 in 2003. Before that there were only: 12 for the whole year of 2002; 11 for the whole of 2001; and 7 for the whole year of 2000. An apparent trend here, though I don't have the 1980s records (that you refer to) to hand.
If, as we assume, these spring birds are migrants from the continent, it raises questions for me about this upward trend. We know the reasons for the upward trend of 'resident' birds - reintroduction and decline in persecution - but what would explain the apparent increase in migratory birds? Is it because there is a similar swell in numbers on the continent feeding the migration, or are these birds returning 'British' birds from the swelled numbers just referred to? There may be records from tagged birds which help answer this question. Any knowledge out there on the forum?
