Has spring sprung?

Prescot reservoirs,
A chiffchaff was singing and showing well this morning in yates wood. Possibly a spring migrant or possibly a wintering bird enjoying the morning sunshine. Green woodpecker seen and heard today and 2 stonechats on the north fence. A harris hawk with jessies flew over the meadow mid morning. 3 woodcock also. Pretty quiet on the gull front with lesser black backed numbers building up.
