First real migrant?

A Blackcap in subsong in the Blackthorn near the benches at Lavell's, is the first of the year, 98 for the park, 95 for me. The second earliest record, but no real way of knowing if it is a summer migrant, or a winter bird moving thru. Oh well I'll take it anyway. 2 Oystercatcher on Tern scrape, Redshank here and on LFGP, 1 Little Egret & 4 Goldeneye there too. Darn cold again this morning.
