The Early Bird?




The recent RSPB report on the State of UK Birds Survey (http://www.rspb.org.uk/ourwork/science/sotukb/index.asp) apparently suggests that birds ,such as the Chaffinch (Fringilla coelebs) and the European robin (Erithacus rubecula), are laying eggs about a week earlier than in the 1960s is intriguing. Similar patterns are said to be evident in Blue (Cyanistes caeruleus) and Great (Parus major) tits. Again, it may be a bit of a leap to relate this to climate change but locally it is said by CCW that Pied flycatcher young in Welsh oak woodlands are emerging in spring before the necessary insect food (caterpillars) is available. It has also been reported that migratory birds are having to travel further in find appropriate conditions.
